Abstract
INTRODUCTION Dietary self-monitoring in behavioral weight loss programmes traditionally involves keeping track of all foods and beverages to achieve a calorie deficit. While effective, adherence declines over time. WW™ (formerly Weight Watchers), a widely available commercial weight management programme, sought to pilot an approach that permitted participants to consume over 200 foods without monitoring them. METHODS The current study used a pre-post evaluation design with anthropometric, psychosocial and physical health assessments at baseline, 3 and 6 months. RESULTS Participants (N = 152) were, on average, 48.4 (±12.3) years old, with body mass index (BMI) of 32.8 (±4.8) m/kg2 and 94% female. Mean weight loss was 6.97 + 5.55 kg or 7.9 ± 6.1% of initial body weight (ps < .0001) at 6 months. One third (32.6%) of the sample lost 10% or more of initial body weight. Significant improvements in hunger, cravings, happiness, sleep, quality of life, aerobic stamina, flexibility and blood pressure were observed. Attendance at group meetings, as well as decreases in hunger, and fast food cravings from baseline to 3 months were associated with achieving 10% weight loss at 6 months (p < .01). CONCLUSIONS Using an approach that does not require self-monitoring of all foods and beverages produced significant weight losses and other physical and psychosocial improvements.

Bourke S, Morton JM, Williams P. Effect of JumpstartMD, a Commercial Low-Calorie Low-Carbohydrate Physician-Supervised Weight Loss Program, on 22,407 Adults. J Obes 2020; 2020:8026016. [PMID: 32318289 PMCID: PMC7157789 DOI: 10.1155/2020/8026016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2019] [Revised: 09/10/2019] [Accepted: 11/14/2019] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Commercial weight loss programs provide valuable consumer options for those desiring support. Several commercial programs are reported to produce ≥3-fold greater weight loss than self-directed dieting. The effectiveness of JumpstartMD, a commercial pay-as-you-go program that emphasizes a low-to-very-low-carbohydrate real-food diet and optional pharmacologic treatment without prepackaged meals or meal replacement, has not previously been described. METHODS Completer and last observation carried forward (LOCF) of clinic-measured weight loss (kg) in 18,769 female and 3638 male JumpstartMD participants. RESULTS Completers lost (mean ± SE) 8.7 ± 0.04 kg, 9.5 ± 0.04% with 44.5 ± 0.5% achieving ≥10% weight loss at 3 months (mo, N = 14,999 completers); 11.8 ± 0.1 kg, 12.6 ± 0.1% with 66.4 ± 0.6% achieving ≥10% weight loss at 6 mo (N = 11,805); and 11.5 ± 0.2 kg, 12.0 ± 0.2% with 57.6 ± 0.9% achieving ≥10% weight loss at 12 mo (N = 8514). LOCF estimates were -6.5 ± 0.03 kg, -7.2 ± 0.03% with 27.1 ± 0.3% achieving ≥10% weight loss at 3 mo; -7.7 ± 0.04 kg, -8.5 ± 0.04% with 36.3 ± 0.3% achieving ≥10% weight loss at 6 mo; and -7.7 ± 0.1 kg, -8.4 ± 0.1% with 34.6 ± 0.3% achieving ≥10% weight loss after 12 mo. Frequent health coach meetings was a major determinant of weight loss, with women and men attending ≥75% of their weekly appointments losing 8.8 ± 0.04 and 11.9 ± 0.1 kg, respectively, after 3 mo, 13.1 ± 0.1 and 16.5 ± 0.3 kg after 6 mo, and 16.5 ± 0.3 and 19.4 ± 0.8 kg after 12 mo. Phentermine and phendimetrazine had a minor effect in women only at 1 (6.1% greater weight loss than untreated), 2 (4.1%), and 3 mo (1.2%), but treated patients showed longer enrollment than nontreated during the first 3 (females: +0.4 ± 0.01; males: +0.3 ± 0.04 mo), 6 (females: +1.1 ± 0.04; males: +1.0 ± 0.1 mo), and 12 mo (females: +2.7 ± 0.1; males: +2.4 ± 0.2 mo). JumpstartMD produced generally greater weight loss than published reports for other real-food and prepackaged-meal commercial programs and somewhat greater or comparable losses to meal replacement diets. CONCLUSION A one-on-one medically supervised program that emphasized real low-carbohydrate foods produced effective weight loss, particularly in those attending ≥75% of their weekly appointments.

Abstract
OBJECTIVE To evaluate a commercially available, structured short-term weight management program designed for adolescents with obesity delivered by nonhealth professionals. STUDY DESIGN A multisite parallel-group randomized controlled trial was conducted to evaluate a commercial 12-week lifestyle behavioral program in commercial weight management centers in Australia. Eligible participants (13-17 years, body mass index (BMI) z score ?1.282 with no presenting morbidities) were randomized (n?=?88) to intervention or wait-list, and the program was delivered by consultants at participating weight management centers. The primary outcome was change in BMI z score. Secondary outcomes included the psychometric variables quality of life, body-esteem, and self-esteem. Data was analyzed according to intention-to-treat principles. RESULTS Of 74 participants who consented to enter the study, 66 provided baseline anthropometric data and 12-week data were available for 55 individuals (74%). A significantly greater decrease in BMI z score in the intervention group (n?=?32) was observed when compared with the wait-list control group, mean difference (MD)?=??0.27?kg/m2; 95% CI, ?0.37,?0.17; P?<?.001). Participants allocated to receive the lifestyle intervention reported a greater improvement in body esteem (MD = 1.7, 95% CI, 0.3, 3.1; P?=?.02) and quality of life (MD?=?5.9, 95% CI, 0.9, 10.9; P?=?.02) compared with the wait-list control group. CONCLUSIONS A structured lifestyle intervention delivered by a commercial provider in an adolescent population can result in clinically relevant weight loss and improvements in psychosocial outcomes in the short term. Further research is required to evaluate long-term outcomes. TRIAL REGISTRATION International Clinical Trials Registry: ISRCTN13602313.

Abstract
Using the Guidelines for the Management of Overweight and Obesity in Adults as a framework, this article reviews intensive lifestyle interventions for weight loss. The Guidelines recommend a minimum of 6 months of high-intensity, comprehensive lifestyle intervention, consisting of a reduced-calorie diet, increased physical activity, and behavior therapy. Persons with obesity typically lose approximately 8 kg (approximately 8% of initial weight) with this approach, accompanied by improvements in health and quality of life. To prevent weight regain, the Guidelines recommend a 1-year weight loss maintenance program that includes at least monthly counseling with a trained interventionist. Lifestyle interventions usually are delivered in-person; however, treatment increasingly is being disseminated through community- and commercial-based programs, as well as delivered by telephone, Internet, and smartphone platforms. These latter modalities expand treatment reach but usually produce smaller weight losses than in-person interventions. The review concludes with an examination of challenges in weight management.

Abstract
OBJECTIVE We examined the glycemic benefits of commercial weight loss programmes as compared with control/education or counselling among overweight and obese adults with and without type 2 diabetes mellitus (T2DM). METHODS We searched MEDLINE, Cochrane Database of Systematic Reviews, and references cited by individual programmes. We included randomized controlled trials of ≥12 weeks duration. Two reviewers extracted information on study design, population characteristics, interventions, and mean changes in haemoglobin A1c and glucose. RESULTS We included 18 randomized controlled trials. Few trials occurred among individuals with T2DM. In this population, Jenny Craig reduced A1c at least 0.4% more than counselling at 12 months, Nutrisystem significantly reduced A1c 0.3% more than counselling at 6 months, and OPTIFAST reduced A1c 0.3% more than counselling at 6 months. Among individuals without T2DM, few studies evaluated glycemic outcomes, and when reported, most did not show substantial reductions. DISCUSSION Few trials have examined whether commercial weight loss programmes result in glycemic benefits for their participants, particularly among overweight and obese individuals without T2DM. Jenny Craig, Nutrisystem and OPTIFAST show promising glycemic lowering benefits for patients with T2DM, although additional studies are needed to confirm these conclusions. © 2016 World Obesity.

Abstract
PURPOSE To quantify the impact of a commercial weight management program on weight change in obese patients with coronary heart disease. METHODS An observational, single-center pilot study in the Netherlands. Forty-five patients diagnosed with a recent acute coronary syndrome and a body mass index of >30 kg/m2 were recruited. The commercial weight management intervention (Weight Watchers) promotes a hypoenergetic and balanced diet, increased physical activity, and group support. The program included weekly 30-minute in-hospital meetings with an experienced coach. The program was offered in parallel with a cardiac rehabilitation program. RESULTS Thirty-five patients completed the program. Of these patients, 32 patients (91%) decreased body weight. Mean weight change was -5.8 kg (range: +0.6 kg to -15.4 kg), and 20 patients (57%) achieved the target of 5% weight loss of their initial weight. Twenty-seven patients continued the commercial weight loss program after 14 weeks, the mean followup of these patients was 34 weeks and their mean weight change was -9.1 kg (range: 0.0-23.0 kg). CONCLUSIONS Obese patients, discharged after an acute coronary syndrome, who were referred to a commercial weight management program, achieved significant weight loss. Although this is a nonrandomized pilot study with patients who were selected by motivation and by the ability to participate in the program, the proportion of weight loss is significant and promising.

Abstract
AbstractObjectiveTo examine the weight-loss success associated with distinct dietary patterns and to determine changes of these dietary patterns during participation in a web-based weight-reduction programme.DesignFactor analysis was used to identify the dietary patterns of twenty-two food groups that were administered in 14 d dietary protocols at baseline and after 3 months. Successful weight loss (≥5 % of initial weight) and BMI were calculated. Logistic regression analyses were used to assess the rates of weight-loss success from each dietary pattern and changing or remaining in the initial dietary pattern. A generalised linear mixed model was used to estimate the effects of changing or staying in a dietary pattern on change in BMI.SubjectsAdults (n 1635) aged 18–81 years.SettingUsers of a web-based weight-reduction programme (2006–2012).ResultsParticipants who aligned to a healthful dietary pattern at baseline (OR=1·8; 95 % CI 1·5, 2·3) and after 3 months (OR=1·5; 95 % CI 1·2, 1·9) had a greater chance of successfully losing weight. After adjusting for age, sex, initial dietary pattern and BMI, participants who started with or changed to the healthful dietary pattern had a greater chance of being successful (OR=1·4; 95 % CI 1·1, 1·7) and a higher BMI reduction of 0·30 (95 % CI 0·2, 0·5) kg/m2 compared with those who started with or changed to the energy-dense or high-carbohydrate dietary pattern.ConclusionsA favourable healthful dietary pattern at the beginning and after 3 months was positively associated with anthropometry. However, successful weight loss was feasible in each dietary pattern.

Abstract
The objective was to develop a set of "best practices" for use as a primer for those interested in entering the clinical trials field for lifestyle diet and/or exercise interventions in osteoarthritis (OA), and as a set of recommendations for experienced clinical trials investigators. A subcommittee of the non-pharmacologic therapies committee of the OARSI Clinical Trials Working Group was selected by the Steering Committee to develop a set of recommended principles for non-pharmacologic diet/exercise OA randomized clinical trials. Topics were identified for inclusion by co-authors and reviewed by the subcommittee. Resources included authors' expert opinions, traditional search methods including MEDLINE (via PubMed), and previously published guidelines. Suggested steps and considerations for study methods (e.g., recruitment and enrollment of participants, study design, intervention and assessment methods) were recommended. The recommendations set forth in this paper provide a guide from which a research group can design a lifestyle diet/exercise randomized clinical trial in patients with OA.

Abstract
BACKGROUND Commercial and proprietary weight-loss programs are popular obesity treatment options, but their efficacy is unclear. PURPOSE To compare weight loss, adherence, and harms of commercial or proprietary weight-loss programs versus control/education (no intervention, printed materials only, health education curriculum, or <3 sessions with a provider) or behavioral counseling among overweight and obese adults. DATA SOURCES MEDLINE and the Cochrane Database of Systematic Reviews from inception to November 2014; references identified by program staff. STUDY SELECTION Randomized, controlled trials (RCTs) of at least 12 weeks' duration; prospective case series of at least 12 months' duration (harms only). DATA EXTRACTION Two reviewers extracted information on study design, population characteristics, interventions, and mean percentage of weight change and assessed risk of bias. DATA SYNTHESIS We included 45 studies, 39 of which were RCTs. At 12 months, Weight Watchers participants achieved at least 2.6% greater weight loss than those assigned to control/education. Jenny Craig resulted in at least 4.9% greater weight loss at 12 months than control/education and counseling. Nutrisystem resulted in at least 3.8% greater weight loss at 3 months than control/education and counseling. Very-low-calorie programs (Health Management Resources, Medifast, and OPTIFAST) resulted in at least 4.0% greater short-term weight loss than counseling, but some attenuation of effect occurred beyond 6 months when reported. Atkins resulted in 0.1% to 2.9% greater weight loss at 12 months than counseling. Results for SlimFast were mixed. We found limited evidence to evaluate adherence or harms for all programs and weight outcomes for other commercial programs. LIMITATION Many trials were short (<12 months), had high attrition, and lacked blinding. CONCLUSION Clinicians could consider referring overweight or obese patients to Weight Watchers or Jenny Craig. Other popular programs, such as Nutrisystem, show promising weight-loss results; however, additional studies evaluating long-term outcomes are needed. PRIMARY FUNDING SOURCE None.

Abstract
BACKGROUND The US Preventive Services Task Force (USPSTF) recommends that clinicians refer obese adults for intensive, multicomponent behavioral counseling, yet most obese Americans choose a self-help approach to lose weight. The current study examined weight loss between a community-based, intensive behavioral counseling program (Weight Watchers program) and a self-help condition. METHODS A total of 292 participants were randomized to either a Weight Watchers condition (WW) (n = 147) or a self-help condition (n = 145). Participants in the WW condition were provided with 3 ways to access the treatment: weekly meetings; WW mobile application; and WW online tools. Weights were measured at baseline and at 3 and 6 months. Additionally, self-report use of access modes was collected at 3 and 6 months. RESULTS Participants in the WW condition significantly decreased their body mass index at 6 months (F = 36.7, P <.001) and were 8.0 and 8.8 times more likely to achieve a 5% and 10% reduction in weight, respectively, compared with those in the self-help condition. In a secondary analysis, high usage of all 3 access modes resulted in the greatest weight loss (P <.001). CONCLUSION Use of the WW program yielded significantly greater weight loss than a self-help approach, suggesting it is a viable community-based provider of weight loss treatment, as recommended by the USPSTF. Further, high usage of 3 access modes was associated with greater weight loss results.

Abstract
Objective: To compare the efficacy of a popular commercial program with that of a clinic-based intervention for weight loss. Methods: Randomized clinical trial conducted at an internal medicine clinic affiliated with a city hospital in Denver, Colorado. Participant (n = 46) had a body mass index ≥ 30 kg/m2 and no life-threatening medical conditions. They either were provided a voucher to attend Weight Watchers for 17 weeks (n = 23), or they were assigned to the clinic group (n = 23), which provided 12 visits over 17 weeks and the option to augment weight loss using either meal replacements or weight loss medication. The primary study outcome was weight change. Results: Participants assigned to the clinic arm lost 4.0 ± 1.2 kg, compared to 0.4 ± 1.1 for those assigned to the commercial program ( P = .04 for difference). Weight losses in the clinic arm were 3.2 kg for meal replacements (n = 10) and 5.0 kg for phentermine (n = 13). Conclusions: In this single-site trial, a clinic-based intervention was more effective than a popular commercial program for weight loss. Primary care providers in the United States are under increasing pressure to combat the epidemic of obesity. This trial, although small, begins to address how the primary care setting might play that role.

Abstract
OBJECTIVE To assess the accuracy of body composition measurements by air displacement plethysmography and bioelectrical impedance analysis (BIA) compared with DXA during weight loss. RESEARCH METHODS AND PROCEDURES Fifty-six healthy but overweight participants, 34 women and 22 men (age, 52 +/- 8.6 years; weight, 92.2 +/- 11.6 kg; BMI, 33.3 +/- 2.9 kg/m(2)) were studied in an outpatient setting before and after 6 months of weight loss (weight loss, 5.6 +/- 5.5 kg). Subjects were excluded if they had initiated a new drug therapy within 30 days of randomization, were in a weight loss program, or took a weight loss drug within 90 days of randomization. Subjects were randomly assigned either to a self-help program, consisting of two 20-minute sessions with a nutritionist and provision of printed materials and other self-help resources, or to attendance at meetings of a commercial program (Weight Watchers). Body composition was examined by each of the methods before and after weight loss. RESULTS BIA (42.4 +/- 5.8%) underestimated percentage fat, whereas the BodPod (Siri = 51.7 +/- 6.9%; Brozek = 48.5 +/- 6.5%) overestimated percentage fat compared with DXA (46.1 +/- 7.9%) before weight loss. Correlation coefficients for detecting changes in body composition between DXA and the other methods were relatively high, with Brozek Deltafat mass (FM; r(2) = 0.63), Siri FM (r(2) = 0.65), tetrapolar BIA percentage fat (r(2) = 0.57), and Tanita FM (r(2) = 0.61) being the highest. DISCUSSION In conclusion, all of the methods were relatively accurate for assessing body composition compared with DXA, although there were biases. Furthermore, each of the methods was sensitive enough to detect changes with weight loss.

Abstract
Intensive obesity treatment is mandated by federal health care reform but is costly. A partial subsidy for obesity treatment could lower the cost of treatment, without reducing its efficacy. This study sought to test whether a partial subsidy for obesity treatment would be feasible, as compared to a fully subsidized intervention. The study was a pilot randomized trial. Participants (n = 50) were primary care patients with obesity and at least one comorbid condition (diabetes, hypertension, dyslipidemia, or obstructive sleep apnea). Each participant received eight weight loss counseling visits as well as portion-controlled foods for weight loss. Participants were randomized to full subsidy or partial subsidy (2 vs. 1 meal per day provided). The primary outcome was weight change after 4 months. Secondary outcomes included changes in blood pressure, waist circumference, and health-related quality of life. Participants in the full and partial subsidy groups lost 5.9 and 5.3 kg, equivalent to 5.3% and 5.1% of initial weight, respectively (P = 0.71). Changes in secondary outcomes were similar in the two groups. A partial subsidy was feasible and induced a clinically similar amount of weight loss, compared to a full subsidy. Large-scale testing of economic incentives for weight control is merited given the federal mandate to offer weight loss counseling to obese patients.

Abstract
OBJECTIVE The purpose of this study was to report preliminary data on the effects of tea and high-protein meal replacement shakes on weight loss, waist-to-hip ratios, and lipid profiles in healthy subjects. Secondary analyses of urine samples assessed pre-post changes in cellular biochemistry, neurochemistry, and microbial metabolism. METHODS This study used a pre-post intervention design without a control group. Thirty healthy subjects (20-60 years of age; 23 women and 7 men) participated in a 28-day diet intervention program consisting of a cleansing day and 6 restricted diet days per week. On cleansing days, the subjects drank 4 oz of tea 4 times per day with a recommendation to drink at least 64 oz of filtered water. On the restricted diet days, the subjects drank 2 high-protein meal replacement shakes, consumed one 400- to 600-cal (1674.3-2511.5 joules) meal consisting of low-glycemic index foods, and drank at least 64 oz of filtered water. RESULTS Multiple paired t tests detected reductions in weight (6.4 lb), waist (1.9 in), and hip (1.1 in) measurements and in total cholesterol (13.3 mg/dL) and low-density lipoprotein cholesterol (11.4 mg/dL) (P < .05). Multiple paired t tests detected significant increases in energy metabolism from carbohydrates and amino acids and concomitant increases in oxidative stress (P < .05). CONCLUSION The data support the concept that a low-glycemic load diet intervention incorporating tea and high-protein meal replacement shakes may cause weight loss and improve lipid profiles. The significant physiologic changes from the urine samples did not reflect meaningful metabolic effects.

Abstract
Social networks are increasingly recognized as important determinants of many chronic diseases, yet little data exist regarding the influence of social networks on diabetes. We surveyed diabetic patients to determine how social networks affect their overall level of concern regarding diabetes and its complications. We adapted a previously published instrument and surveyed 240 diabetic patients at two primary care practices. Patients recorded the number of family and friends who had diabetes and rated their level of concern about diabetes on a scale of 0% (no concern) to 100% (extremely concerned). Our primary outcome variable was patients' level of concern (<75% or ≥75%). We developed logistic regression models to determine the effect of disease burden in patients' social networks on expressed level of concern about diabetes. We received 154 surveys (64% response rate). We found that for each additional family member with diabetes, patients expressed a greater level of concern about diabetes (AOR 1.5; 95% CI 1.2-2.0) and its potential complications (AOR 1.4; 95% CI 1.1-1.7). Similarly, patients with an increased number of friends with diabetes expressed greater concern about diabetes (AOR 1.5; 95% CI 1.2-1.9) and its complications (AOR 1.3; 95% CI 1.1-1.7). Patients with a higher prevalence of diabetes within their social networks expressed greater concern about diabetes and diabetic complications. Determining disease burden within patients' social networks may allow physicians to better understand patients' perspectives on their disease and ultimately help them achieve meaningful behavioral change.

Abstract
This review has shown that behavioral treatment is effective in inducing a 10% weight loss, which is sufficient to significantly improve health. Weight loss maintenance is challenging for most patients. Long-term outcomes have the potential to be improved through various methods including prolonging contact between patients and providers (either in the clinic or via Internet or telephone), facilitating high amounts of physical activity, or combining lifestyle modification with pharmacotherapy. Innovative programs also are being developed to disseminate behavioral approaches beyond traditional academic settings.

Abstract
BACKGROUND The Internet provides a widely accessible platform for weight loss interventions. Automated tools can allow self-guided monitoring of food intake and other target behaviours that are established correlates of weight change. Many programmes also offer social support from the virtual community. The aim of this research was to assess associations between engagement with self-monitoring tools and social support, and weight loss in an online weight-control programme. METHODS This paper describes a retrospective analysis of weight change among 3621 subscribers to a commercial Internet-based weight loss programme. Participants were all subscribers (2979 women; 642 men) joining the programme between July 2005 and November 2008 with two or more recorded weights spanning at least 28 days of participation in the programme. Engagement was indexed with frequency of using online diet and exercise diaries and with use of the social support forums. RESULTS Programme engagement was associated with weight loss in both men and women after controlling for initial BMI and duration of participation. The three engagement variables accounted for 13% of variance in percentage weight loss in women (p < .001) and 19% in men (p < .001). In analyses including all the engagement variables, exercise diary use was an independent predictor of weight loss among men, but non-significant in women. In contrast, use of the online forums was associated with weight loss in women but not in men. Among participants who were overweight or obese, those in the highest tertile of engagement with food diaries (vs the lowest) were more likely to achieve clinically significant (> 5%) weight loss (men: OR = 3.45 p < .001; women: OR = 5.05 p < .001). Being in the highest tertile of engagement with exercise diaries was associated with clinically significant weight loss in men (OR = 3.48 p < .001) and, less strongly, in women (OR = 1.46 p < .05). CONCLUSIONS Use of self-monitoring tools and participation in online support are predictive of weight loss in the context of a commercial, online weight control programme.

Abstract
Objective. To assess the effectiveness of a commercial nutrition program in improving weight, blood lipids, and health-related quality of life (HRQOL). Methods. Prospective observational study with followup after 1, 3, 6, and 12 months with data from questionnaires and blood samples. Subjects. After 12 months, we had data from 524 subjects (= 60.6% of the initial samples). 84.1% of the subjects were women. The average BMI at baseline was 30.3 (SD = 5.7). Results. After 12 months, the average weight loss was 6.8 kg (SD = 7.1 kg). Program adherence declined over time but was still high after 12 months and showed a positive linear correlation with weight loss. Relevant blood parameters as well as HRQOL improved significantly. Conclusion. After 12 months, nearly two thirds of the samples had achieved >5% reduction of their initial weights. The high degree of program adherence is probably due to personal counseling and individually designed nutrition plans provided by the program.

Abstract
The prevalence of obesity in the developed world is increasing. Approximately 23% of adult Canadians (5.5 million people) are obese. Obesity is associated with an increased risk of developing several comorbid diseases, ranging from cardiovascular diseases to cholelithiasis and nonalcoholic fatty liver disease. The etiology of obesity is multifactorial, involving a complex interaction among genetics, hormones and the environment. The available evidence and recommendations for nonpharmacological management of obesity, including dietary therapy, physical activity and behavioural therapy, in addition to pharmacotherapy are discussed. A brief discussion on endoscopic and surgical procedures is undertaken. Several antiobesity treatment options are available and may be indicated in appropriate situations. Selecting obesity therapy may be guided by body mass index measurements, comorbid illnesses and patient preference.

Abstract
OBJECTIVES To assess participation in a costed Slimming on Referral service and identify factors associated with success. STUDY DESIGN Simple intervention offering participation in a new service to 100 eligible patients. The setting was two Derby general practices, one inner city and one suburban. PARTICIPANTS One hundred and seven patients (mean age 50 years) attending general practice for non-obesity reasons. INCLUSION CRITERIA BMI > or = 30, age > or = 18 years, not pregnant, no recent commercial weight management group membership, willingness to attempt weight loss. METHODS Patients were offered free attendance at a local Slimming World group for 12 consecutive weeks. Body weight and height were measured at baseline, and questionnaires established perceived health, motivation to lose weight, employment, concerns, responsibilities and well-being. Weight was measured at each group visit. The main outcome measures were: (1) changes in body weight at 12 and 24 weeks, (2) social and demographic factors associated with barriers to enrolment, continued attendance and successful weight loss. RESULTS Ninety-one (85%) patients attended a group, with 62 completing 12 weeks. Average weight loss in participants was 5.4 kg (6.4% baseline weight). Forty-seven then chose to self-fund, with 34 (37% original group) completing a further 12 weeks. Average weight loss over the total 24 weeks was 11.1 kg (11.3% baseline weight). Regular attendance was affected by income, financial concerns (independent of actual income), age, perceived importance of weight loss and initial weight loss success. Well-being of patients significantly improved between baseline and both 12 and 24 weeks. CONCLUSIONS Collaboration with an appropriate commercial weight management organization offers a feasible weight management option that is either similar to, or better than, other options in terms of attrition, efficacy and cost.

Abstract
Obesity and its associated disorders are a growing epidemic across the world. Many genetic, physiological, and behavioral factors play a role in the etiology of obesity. Diet and exercise are known to play a valuable role in the treatment and prevention of obesity and associated disorders such as hypertension, heart disease, and diabetes. Therefore, the purpose of this review is to examine the prevalence, etiology, consequences, and treatment of obesity.

Abstract
The early stages of dieting to lose weight have been associated with neuro-psychological impairments. Previous work has not elucidated whether these impairments are a function solely of unsupported or supported dieting. Raised cortico-steroid levels have been implicated as a possible causal mechanism. Healthy, overweight, pre-menopausal women were randomised to one of three conditions in which they dieted either as part of a commercially available weight loss group, dieted without any group support or acted as non-dieting controls for 8 weeks. Testing occurred at baseline and at 1, 4 and 8 weeks post baseline. During each session, participants completed measures of simple reaction time, motor speed, vigilance, immediate verbal recall, visuo-spatial processing and (at Week 1 only) executive function. Cortisol levels were gathered at the beginning and 30 min into each test session, via saliva samples. Also, food intake was self-recorded prior to each session and fasting body weight and percentage body fat were measured at each session. Participants in the unsupported diet condition displayed poorer vigilance performance (p = 0.001) and impaired executive planning function (p = 0.013) (along with a marginally significant trend for poorer visual recall (p = 0.089)) after 1 week of dieting. No such impairments were observed in the other two groups. In addition, the unsupported dieters experienced a significant rise in salivary cortisol levels after 1 week of dieting (p < 0.001). Both dieting groups lost roughly the same amount of body mass (p = 0.011) over the course of the 8 weeks of dieting, although only the unsupported dieters experienced a significant drop in percentage body fat over the course of dieting (p = 0.016). The precise causal nature of the relationship between stress, cortisol, unsupported dieting and cognitive function is, however, uncertain and should be the focus of further research.

Abstract
Although commonly addressed in magazines, across airwaves, and within gyms nationwide, health care providers must now face the growing epidemic of obesity in their daily practice. With the graying of America, it is all the more important to realize that weight increases the risk for disease and mortality in the elderly. Despite overwhelming evidence that weight loss can reduce health risks, many patients who are overweight never receive needed advice from their primary care physicians. This article addresses the barriers to physician intervention, methods to assess obesity risk, and readiness to change. Effective approaches for assisting in successful weight loss and maintenance are discussed.

Abstract
A obesidade é a forma mais comum de má-nutrição e sua prevalência vem aumentando muito, inclusive no Brasil. A internet, apesar de ainda pouco explorada, pode ser útil no tratamento da obesidade como ferramenta na utilização de técnicas comportamentais. O objetivo deste trabalho foi avaliar o uso da internet no tratamento da obesidade em uma amostra de adultos da cidade de Lagoa dos três Cantos, RS, onde 58,6% dos habitantes tinha IMC acima de 25kg/m². Os indivíduos com excesso de peso (n= 532) foram submetidos a um programa de emagrecimento via internet com dieta hipocalórica e auxílio de técnicas comportamentais. Foi observada diminuição do peso médio em relação ao inicial aos 2º, 5º, 8º e 13º meses, respectivamente: 354 indivíduos (66,6%) perderam mais do que 5%, sendo que 106 (20%) perderam mais do que 10% do peso inicial. Estes resultados demonstram que o acompanhamento pela internet pode ser útil no combate ao excesso de peso e obesidade.

Abstract
The increasing prevalence of obesity has been mirrored by a parallel increase in the number of commercial weight loss programmes. Research evaluating these programmes is meagre, however, compared to the numbers treated. Reluctance of commercial weight loss programmes to meaningfully evaluate their weight loss efficacy may arise from fear that competitors will use the results against them. Evaluation of commercial weight loss programmes usually progresses from testimonials, often by famous people who were successful, to uncontrolled studies of past participants evaluated either by the programme itself or by an outside entity. The gold standard, however, is a scientifically rigorous, controlled study of the programme conducted by an independent entity. Such a study, published in a peer-reviewed journal, can gain credibility for a programme, as it did with Slim Fast, if the results are positive, or herald the end of the programme, as it was with Simeons human chorionic gonadotropin injection clinics. This review of the evolution of the evaluation process of commercial weight loss programmes leads us to conclude that consumers are likely to demand greater scientific rigour in the future, a change that will favour informed choice and discourage the practice of unrealistic advertising that raises false hopes.

Abstract
OBJECTIVE To determine if home-centered monitoring through telemedicine has an impact on clinical characteristics, metabolic profile and quality of life in overweight and obese patients. DESIGN Randomized controlled trial, 6-month duration. SETTING Tertiary care academic hospital. SUBJECTS A total of 122 patients were eligible to participate as they met the inclusion criteria of increased body mass index (BMI>25 kg/m(2)), age>18 and <70 y and ability to operate electronic microdevices. INTERVENTIONS All patients in the control group (n=77) received standard hospital care. Patients in the intervention group (n=45), additionally, measured three times a week, for 6 months, their blood pressure and body weight and transmitted them to an automated call center. These values were not shared with the patients' physician or dietician. MAIN OUTCOME MEASURES Clinical (body weight, BMI, blood pressure), laboratory (fasting plasma glucose, triglycerides, HDL-cholesterol, total cholesterol) and quality of life parameters (SF-36((R)), Visual Analog Scale of European Quality-5 Dimensions, Obesity Assessment Survey). Data were analyzed in an intention-to-treat-way (last observation carried forward). RESULTS Drop-out rate was similar in the control and intervention groups: 12 vs 11 percent, respectively, P=NS. There were no significant differences at baseline between intervention and control groups in all main outcome parameters. There were significant decreases for patients in the intervention group in body weight (from 101.6+/-22.4 to 89.2+/-14.7 kg, P=0.002, P=0.05 vs controls at 6 months), total cholesterol (from 247.6+/-42.0 to 220.7+/-42.6 mg/dl, P=0.002, P=0.05 vs controls at 6 months) and triglycerides (from 148.4+/-35.0 to 122.3+/-31.4 mg/dl, P=0.001, P=0.01 vs controls at 6 months). Intervention group patients made a total of 1997 phone contacts. The number of phone contacts was correlated positively with Social Functioning (SF), Vitality (VT) and Mental Health (MH) scores of SF-36((R)) at baseline (r=0.48, r=0.41, r=0.41, respectively, P=0.05) but not with weight loss. CONCLUSIONS Home-centered, intense treatment through the use of telemedicine can be effective in improving short-term obesity outcomes.

Abstract
OBJECTIVE To compare the long-term compliance and effects of two low-fat diets differing in carbohydrate to protein ratio on body composition and biomarkers of cardiovascular disease risk in obese subjects with hyperinsulinemia. DESIGN Outpatient, parallel, clinical intervention study of two groups of subjects randomly assigned to either a standard protein (SP; 15% protein, 55% carbohydrate) or high-protein (HP; 30% protein, 40% carbohydrate) diet, during 12 weeks of energy restriction (approximately 6.5 MJ/day) and 4 weeks of energy balance (approximately 8.3 MJ/day). Subsequently, subjects were asked to maintain the same dietary pattern for the succeeding 52 weeks with minimal professional support. SUBJECTS A total of 58 obese, nondietetic subjects with hyperinsulinemia (13 males/45 females, mean age 50.2 y, mean body mass index (BMI) 34.0 kg/m2, mean fasting insulin 17.8 mU/l) participated in the study. MEASUREMENTS : Body composition, blood pressure, blood lipids, fasting glucose, insulin, CRP and sICAM-1 were measured at baseline and at weeks 16 and 68. Urinary urea/creatinine ratio was measured at baseline, week 16 and at 3 monthly intervals thereafter. RESULTS In total, 43 subjects completed the study with similar dropouts in each group (P=0.76). At week 68, there was net weight loss (SP -2.9+/-3.6%, HP -4.1+/-5.8%; P<0.44) due entirely to fat loss (P<0.001) with no diet effect [corrected]. Both diets significantly increased HDL cholesterol concentrations (P<0.001) and decreased fasting insulin, insulin resistance, sICAM-1 and CRP levels (P<0.05). Protein intake was significantly greater in HP during the initial 16 weeks (P<0.001), but decreased in HP and increased in SP during 52-week follow-up, with no difference between groups at week 68, indicating poor long-term dietary adherence behaviour to both dietary patterns. CONCLUSION Without active ongoing dietary advice, adherence to dietary intervention is poor. Nonetheless, both dietary patterns achieved net weight loss and improvements in cardiovascular risk factors.

Abstract
Obesity is increasing in epidemic proportions globally while current therapies continue to be suboptimal. In this investigation, weight loss in obese individuals after 24 weeks with different nutrition interventions was compared. The impact of intervention intensity was assessed. Inclusion criteria were established and a comprehensive literature review was performed. These nutrition interventions were identified and analyzable: meal replacements (MRs); energy-restricted (>1500 kcal/d) diets (ERDs); low-energy (800-1500 kcal/d) diets (LEDs); soy very low energy (<800 kcal/d) diets (VLEDs) referred to as SOYs; and VLEDs. Intensity was assessed using the following parameters: physician visits, clinic visits, and hours of class over 24 weeks; an intensity score represents an adjusted sum of the values. Weight losses at 24 weeks as percentage of baseline weights (95%, confidence intervals) were as follows: MRs, 9.1% (5.7-12.5); ERDs, 8.5% (4.9-12.1); LEDs, 11.4% (8.9-13.1); SOYs, 16.5% (13.9-19.1); and VLEDs, 21.3% (20.1-22.5). Weight loss with SOYs was significantly greater than with MRs and ERDs; weight loss with VLEDs was significantly greater than with any other diet. Energy intake was the most significant (P<.0001) regression variable related to weight loss; however, the intensity of intervention (P=.0003) was significantly stronger than initial body weight or duration of treatment. Medically supervised VLEDs are the most effective intervention for facilitating substantial weight loss over 24 weeks. SOY may promote more rapid weight loss over the first 8 weeks than other interventions. MRs appear to be equally effective with ERDs and LEDs with lower levels of intervention intensity.

Abstract
OBJECTIVES To evaluate weight loss maintenance after 4 years of nonpharmacological, nonsurgical obesity treatment, including a very low calorie diet (VLCD), diet and behavioural support. Furthermore, to assess weight development amongst completers and noncompleters beyond the active 4-year treatment period. DESIGN Clinical trial. SETTING Two Swedish county hospitals. SUBJECTS A total of 113 patients were randomized to a 2-year treatment programme with or without an initial VLCD period. The 87 patients who completed the 2-year programme were offered the chance to continue a support programme for another 2 years. A total of 55 patients completed the entire 4-year programme. INTERVENTIONS All the patients took part in a comprehensive support programme, including a hypocaloric diet and behavioural support, either as single treatment (non-VLCD group) or following the VLCD period (VLCD group). RESULTS Significant 4-year weight losses were found in both groups, 7.6 +/- 12.2 kg (VLCD group) and 6.3 +/- 8.5 kg (non-VLCD group), (P < 0.01, n.s. between groups). The completers (n = 55) had maintained a weight loss of 3.3 +/- 10.7 kg (P < 0.05) 8 years after randomization. After 6 years, the noncompleters (n = 58) had gained 3.2 +/- 9.7 kg compared with baseline (P < 0.05). The difference in weight change between completers and non-completers was highly significant (P < 0.01). CONCLUSIONS Highly significant weight losses can be maintained after a 4-year comprehensive treatment programme, including a hypocaloric diet and behavioural support. An initial VLCD period did not significantly affect the long-term weight loss. The posttreatment long-term weight loss was larger amongst completers than amongst patients who did not complete the treatment.

Abstract
OBJECTIVE In 1999, the Partnership for Healthy Weight Management recommended that providers of commercial weight-loss programs (and products) voluntarily disclose information concerning the safety, costs, and central components of their programs, as well as the credentials of program staff. These guidelines were drafted without the benefit of data from consumers concerning the specific information they desired. The present study provides such data. RESEARCH METHODS AND PROCEDURES Participants were 90 women with a mean age of 44.02 +/- 9.17 years and body mass index of 36.11 +/- 4.82 kg/m(2) who were participants in one of two randomized weight-control trials. Before treatment, respondents were asked to imagine that they were "looking for a weight-loss plan" and to rate how important each of 16 factors would be in helping them select a plan. Ratings were made using 5-point scales, anchored by "not at all important" and "extremely important," (scored 1 and 5, respectively). Participants also identified the five factors that they thought were the most important, as well as the single most important. RESULTS The mean rating for the importance of safety (4.57 +/- 0.60) was significantly greater than that for each of the 15 other variables (all p values < 0.05). In addition, significantly more respondents (27.8%) selected safety as the single most important factor than any other variable (all p values < 0.05). Other factors that were consistently judged as very important included information about diet (4.38 +/- 0.68), behavior modification (4.32 +/- 0.76), cost (4.19 +/- 0.92), and maintenance of weight loss (4.15 +/- 0.91). Staff credentials (3.88 +/- 0.83) were among the lowest rated items. DISCUSSION The results generally support the disclosure guidelines proposed by the Partnership for Health Weight Management. Consumers, however, seem to desire information about weight loss, in addition to that concerning safety, cost, and central program components.

Abstract
To determine the effect of a 6-month very low carbohydrate diet program on body weight and other metabolic parameters.Fifty-one overweight or obese healthy volunteers who wanted to lose weight were placed on a very low carbohydrate diet (<25 g/d), with no limit on caloric intake. They also received nutritional supplementation and recommendations about exercise, and attended group meetings at a research clinic. The outcomes were body weight, body mass index, percentage of body fat (estimated by skinfold thickness), serum chemistry and lipid values, 24-hour urine measurements, and subjective adverse effects.Forty-one (80%) of the 51 subjects attended visits through 6 months. In these subjects, the mean (+/- SD) body weight decreased 10.3% +/- 5.9% (P <0.001) from baseline to 6 months (body weight reduction of 9.0 +/- 5.3 kg and body mass index reduction of 3.2 +/- 1.9 kg/m(2)). The mean percentage of body weight that was fat decreased 2.9% +/- 3.2% from baseline to 6 months (P <0.001). The mean serum bicarbonate level decreased 2 +/- 2.4 mmol/L (P <0.001) and blood urea nitrogen level increased 2 +/- 4 mg/dL (P <0.001). Serum total cholesterol level decreased 11 +/- 26 mg/dL (P = 0.006), low-density lipoprotein cholesterol level decreased 10 +/- 25 mg/dL (P = 0.01), triglyceride level decreased 56 +/- 45 mg/dL (P <0.001), high-density lipoprotein (HDL) cholesterol level increased 10 +/- 8 mg/dL (P <0.001), and the cholesterol/HDL cholesterol ratio decreased 0.9 +/- 0.6 units (P <0.001). There were no serious adverse effects, but the possibility of adverse effects in the 10 subjects who did not adhere to the program cannot be eliminated.A very low carbohydrate diet program led to sustained weight loss during a 6-month period. Further controlled research is warranted.

Abstract
OBJECTIVE The objective was to develop effective weight-loss methods for women who have had breast cancer, because obesity may result in an adverse prognosis. RESEARCH METHODS AND PROCEDURES This randomized pilot study tested an individualized approach toward weight loss in obese women who have had a diagnosis of breast cancer. An individualized approach was applied either alone or combined with the commercial Weight Watchers program. Forty-eight women (body mass index of 30 to 44 kg/m(2)) were enrolled. RESULTS Weight change after 12 months of intervention was as follows (mean +/- SD): 0.85 +/- 6.0 kg in the control group, -2.6 +/- 5.9 kg in the Weight Watchers group, -8.0 +/- 5.5 kg in the individualized group, and -9.4 +/- 8.6 kg in the comprehensive group that used both individualized counseling and Weight Watchers. Weight loss relative to control was statistically significant in the comprehensive group 3, 6, and 12 months after randomization, whereas weight loss in the individualized group was significant only at 12 months. Weight loss of 10% or more of initial body weight was observed in 6 of 10 women in the comprehensive group at 12 months. In the comprehensive and Weight Watchers-only groups, weight loss was significantly related to frequency of attendance at Weight Watchers meetings, and attendance was more frequent in the comprehensive group. DISCUSSION These data indicate that the most weight loss was achieved when the counseling approach combined both Weight Watchers and individualized contacts. This was effective even though most of the individualized contacts were by telephone.

Abstract
Obesity has reached epidemic proportions in the United States and other developed nations. In the United States, 27% of adults are obese and an additional 34% are overweight. Research in the past decade has shown that genetic influences clearly predispose some individuals to obesity. The marked increase in prevalence, however, appears to be attributable to a toxic environment that implicitly discourages physical activity while explicitly encouraging the consumption of supersized portions of high-fat, high-sugar foods. Management of the obesity epidemic will require a two-pronged approach. First, better treatments, including behavioral, pharmacologic, and surgical interventions, are needed for individuals who are already obese. The second and potentially more promising approach is to prevent the development of obesity by tackling the toxic environment. This will require bold public policy initiatives such as regulating food advertising directed at children. The authors call not for the adoption of a specific policy initiative, but instead propose that policy research, based on viewing obesity as a public health problem, become a central focus of research.

Abstract
OBJECTIVE This review is designed to quantitate the effects of obesity and weight gain on risk for coronary heart disease (CHD) and to review the effects of weight loss on CHD risk factors. RESEARCH METHODS AND PROCEDURES After a comprehensive review of the literature related to body weight and weight gain on CHD risk, the relative risks (RRs) were tabulated. Values were averaged and meta-analysis techniques were used to estimate the variance-adjusted RR. RESULTS Young persons with higher body mass index values have a significantly higher risk for CHD than do slender young people. For every 1% above a desirable body mass index, the risk for CHD increases by 3.3% for women and by 3.6% for men. Every kilogram of weight gain after high school increases risk for CHD by 5.7% for women and 3.1% for men. Weight loss significantly decreases major CHD risk factors. For every kilogram of weight loss the following favorable changes occur: fasting serum cholesterol, -1.0%; low-density lipoprotein cholesterol, -0.7%; triglycerides, -1.9%; high-density lipoprotein cholesterol, +0.2%; systolic blood pressure, -0.5%; diastolic blood pressure, -0.4%; and blood glucose, -0.2 mM. DISCUSSION Obesity and/or weight gain are associated with major risk for CHD. Weight loss significantly improves serum lipid parameters, blood pressure, and fasting blood glucose values. Effective treatment approaches are available for most overweight or obese individuals but a major challenge is to enable these individuals to engage in these programs. Professional and consumer education is essential for advancing effective intervention strategies for overweight individuals.
