Jumpstarting Health With a 15-Day Whole-Food Plant-Based Program

One Month Whole Food Plant-Based Nutrition Educational Program Lowers LDL, A1C, and Decreases Inflammatory Markers

Lifestyle-related chronic disease increases in the United States have led to the need for innovative programs targeting dietary choices. Based on growing evidence supporting whole food plant-based (WFPB) nutrition to improve overall health, we devised a one-month WFPB intervention program, Jumpstart Your Health! (JYH), to introduce and encourage adoption of the WFPB dietary lifestyle. This paper investigates its effects on various health indicators associated with cardiovascular and metabolic diseases. Among the total of 150 participants, before and after physical measurements and blood chemistries demonstrate significant (p< 0.05) decreases in weight (-4.2 pounds), cholesterol (-25.3 mg/dl), LDL (-19.0 mg/dl), HDL (-5.6 mg/dl), hemoglobin A1c (-0.2%), and hsCRP (-1.9 mg/L). Among the high-risk participants, we found significant decreases in systolic blood pressure (-10 mmHg), diastolic blood pressure (-8.7 mmHg), weight (-4.3 pounds), cholesterol (-38.8 mg/dl), LDL (-22.7 mg/dl), HDL (-2.8 mg/dl), hemoglobin A1c (-0.2 %), and hsCRP (-2.3 mg/L). We demonstrate that a simple WFPB intervention implemented over one month resulted in significant reductions in physical measurements and blood chemistries that could translate to lowered risk or improvement for obesity, cardiovascular disease, and type-2 diabetes.

Recipe for Heart Health: A Randomized Crossover Trial on Cardiometabolic Effects of Extra Virgin Olive Oil Within a Whole-Food Plant-Based Vegan Diet

BACKGROUND

Whole-food, plant-based vegan diets, low in oils, and Mediterranean diets, rich in extra virgin olive oil (EVOO), reduce cardiovascular disease risk factors. Optimal quantity of dietary fat, particularly EVOO, is unclear.

METHODS AND RESULTS

In a randomized crossover trial with weekly cooking classes, adults with ≥5% cardiovascular disease risk followed a high (4 tablespoons/day) to low (<1 teaspoon/day) or low to high EVOO whole-food, plant-based diet for 4 weeks each, separated by a 1-week washout. The primary outcome was difference in low-density lipoprotein cholesterol (LDL-C) from baseline. Secondary measures were changes in additional cardiometabolic markers. Linear mixed models assessed changes from baseline between phases, with age, sex, and body weight change as covariates. In 40 participants, fat intake comprised 48% and 32% of energy during high and low EVOO phases, respectively. Both diets resulted in comparable reductions in LDL-C, total cholesterol, apolipoprotein B, high-density lipoprotein cholesterol, glucose, and high-sensitivity C-reactive protein (all P<0.05). With diet-sequence interactions for LDL-C, differences were detected between diets by diet order (mean±SEM high to low: Δ-12.7[5.9] mg/dL, P=0.04 versus low to high: Δ+15.8[6.8] mg/dL, P=0.02). Similarly, low to high order led to increased glucose, total cholesterol, and high-density lipoprotein cholesterol (all P<0.05). Over period 1, LDL-C reductions were -25.5(5.1) post-low versus -16.7(4.2) mg/dL post-high EVOO, P=0.162, which diminished over period 2.

CONCLUSIONS

Both plant-based diet patterns improved cardiometabolic risk profiles compared with baseline diets, with more pronounced decreases in LDL-C after the low EVOO diet. Addition of EVOO after following a low intake pattern may impede further lipid reductions.

A Review of Plant-Based Diets for Obesity Management

OBJECTIVE

Obesity is the most prevalent chronic disease in the United States with over 70% of the American population suffering from overweight/obesity. Recently, the popularity of plant-based diets (PBDs) has grown, with individuals adopting these diets for ethical, health and environmental reasons. Our aim is to evaluate the effect of a PBD on weight loss among patients who are overweight or obese.

METHODS

A literature review of PBDs for the treatment of obesity was conducted using PubMed and Scopus. Our search yielded 27 intervention trials (3361 participants) and 6 metanalyses (9168 participants, 61 trials).

RESULTS

Among the intervention trials evaluated, 75% showed a significant increase in weight loss or decrease in weight in the intervention group, on average -5.0 kg (range -1.8 to -12.1 kg). Other outcomes included energy intake (-420 Kcal/d), systolic blood pressure (-3.78 mmHg), fasting plasma glucose (-2.0 mmol/L), hemoglobin A1c (-0.5%, -3.4 mmol/L), total cholesterol (-0.40 mmol/L), low-density lipoprotein (-0.38 mmol/L), triglyceride levels (+0.13 mmol/L), and fiber intake (+10.8 g/d). The 6 meta-analyses showed weight loss (average -2.9 kg, range -2.02 kg to -4.1 kg), body mass index reduction, and improvements in hemoglobin A1c, low-density lipoprotein, and total cholesterol.

CONCLUSION

PBDs result in significant weight loss and improve metabolic outcomes. PBDs offer a sustainable approach to long-term weight loss maintenance. Health care providers should encourage open discussions with their patients regarding their dietary habits to assist them in setting feasible lifestyle goals and consider shared medical appointments to support patients in transitioning to PBDs.

Stronger together than apart: The role of social support in adopting a healthy plant-based eating pattern

The influence of the social environment on health behaviors is well documented. In recent years, there is mounting evidence of the health benefits of a plant-based eating pattern, yet little is known about how the social environment impacts the adoption of a plant-based eating pattern, specifically. In this convergent parallel mixed-methods study, we analyzed quantitative survey data and qualitative focus group data to assess how social support impacted participants of a lifestyle medicine intervention focused on the adoption of a plant-predominant eating pattern. Regression analysis of survey data showed a positive association between positive social support and healthy plant-based eating, while no association was found between negative social support and healthy plant-based eating. Focus groups yielded further insights into how positive aspects of social relationships with family and friends facilitated the adoption of plant-predominant eating among participants. Qualitative findings also showed the ways in which negative social support hindered progress to adopt a plant-predominant eating pattern including not eating the same foods as participants, being judgmental about new dietary behaviors, and encouraging participants to eat non-plant-based foods. Taken together, social support appears to be an important factor for individuals adopting a plant-predominant eating pattern. Future research is needed to explore mechanisms to enhance positive social support while mitigating negative aspects of social relationships for individuals participating in similar lifestyle medicine interventions that emphasize on plant-predominant eating.

A whole-food, plant-based program in an African American faith-based population

Background

The African American (AA) population is disproportionately impacted by chronic disease as well as many of the leading causes of preventable death, including hypertension, obesity, heart disease, stroke, and type 2 diabetes. In the AA community of Kane County, Illinois, the incidence of chronic disease is particularly high. A standardized Zoom-based group program that gives participants the knowledge, skills, and support to adopt a whole-food plant-based diet has been shown to rapidly improve health. The results of a cohort analysis were analyzed to assess the effectiveness of this program within an AA community characterized by a high burden of chronic illnesses.

Methods

Participants were recruited from a network of 12 AA churches in Illinois to participate in Rochester Lifestyle Medicine Institute's "15-Day Whole-Food Plant-Based (WFPB) Jumpstart" program. The medically-facilitated 15-Day Jumpstart program provided WFPB nutrition education, coaching, and cooking demonstrations during seven 1 and 2-h Zoom sessions. Participants underwent pre- and post- metabolic screenings to assess for changes in their weight, vital signs, blood sugar, and cholesterol measurements. Changes in diet, biometrics, and patient-centered outcomes from baseline to the end of the program were assessed via paired t-tests for the normally distributed measures, and a Wilcoxon signed rank test for measures that were not normally distributed.

Results

Twenty-one AA adults participated. Ten of 16 who provided results had hypertension, 5 had diabetes, 5 had pre-diabetes, and 5 had hyperlipidemia. Participants ate more vegetables (median 2 servings at baseline vs. 3 during the program), greens (1 vs. 3), fruit (2 vs. 3), whole grains (1 vs. 2), and legumes (1 vs. 2). They decreased their consumption of meat, eggs and dairy, added fat, processed foods, and high-fat plant foods (p < 0.05 for each comparison). Participants reported significantly better energy (median 5 at baseline vs. 9 during the program, on a 10-point scale), sleep (7 vs. 8.5), and mood (8 vs. 9). Average weight loss was 5.8 pounds (199.9 to 194.1, p < 0.001), systolic blood pressure dropped from 129.7 to 119.9 (p = 0.02), and total cholesterol dropped from 185.1 to 147.9 (p < 0.001). All participants who provided data reported an intent to continue eating at least a partially WFPB diet following the program.

Conclusion

The 15-Day WFPB Jumpstart program led to significant changes in diet, resulting in improvement in several chronic disease measures in this AA community. This rapid improvement can reinforce behavior change. Further large-scale implementation is needed to confirm these preliminary results and to understand whether behaviors and outcomes are sustained.

Change in cardiometabolic risk factors in a pilot safety-net plant-based lifestyle medicine program

Introduction

Interventions emphasizing healthful lifestyle behaviors are proliferating in traditional health care settings, yet there is a paucity of published clinical outcomes, outside of pay-out-of-pocket or employee health programs.

Methods

We assessed weight, hemoglobin A1c (HbA1c), blood pressure, and cholesterol for 173 patients of the Plant-Based Lifestyle Medicine Program piloted in a New York City safety-net hospital. We used Wilcoxon signed-rank tests to assess changes in means, from baseline to six-months, for the full sample and within baseline diagnoses (i.e., overweight or obesity, type 2 diabetes, prediabetes, hypertension, hyperlipidemia). We calculated the percentage of patients with clinically meaningful changes in outcomes for the full sample and within diagnoses.

Findings

The full sample had statistically significant improvements in weight, HbA1c, and diastolic blood pressure. Patients with prediabetes or overweight or obesity experienced significant improvements in weight and those with type 2 diabetes had significant improvements in weight and HbA1c. Patients with hypertension had significant reductions in diastolic blood pressure and weight. Data did not show differences in non-high-density lipoprotein cholesterol (non-HDL-C), but differences in low-density lipoprotein cholesterol (LDL-C) were approaching significance for the full sample and those with hyperlipidemia. The majority of patients achieved clinically meaningful improvements on all outcomes besides systolic blood pressure.

Conclusion

Our study demonstrates that a lifestyle medicine intervention within a traditional, safety-net clinical setting improved biomarkers of cardiometabolic disease. Our findings are limited by small sample sizes. Additional large-scale, rigorous studies are needed to further establish the effectiveness of lifestyle medicine interventions in similar settings.

Whole-food plant-based Jumpstart for a Deaf and Hard of Hearing cohort

Deaf and Hard of Hearing (DHH) patients are at high risk of developing chronic illness, and when they do, are at higher risk of poor outcomes than in a hearing community. Rochester Lifestyle Medicine Institute adapted its online, Zoom-based, medically-facilitated 15 Day Whole-Food Plant-Based (WFPB) Jumpstart program, to give DHH participants knowledge, skills, and support to make dietary changes to improve their health. Adaptations included having a medical provider present who is fluent in American Sign Language (ASL), is board-certified in Lifestyle Medicine, and has a Master of Science in Deaf Education; spotlighting participants when asking a question during the Q&amp;A session; using ASL interpreters; utilizing closed captioning/automatic transcription during all Zoom meetings; and employing a Success Specialist to provide outreach via text and email throughout the program. Participants had significant positive changes in their eating pattern. They reported improvements in biometric measures as well as in how they were feeling. They all reported that they planned to continue to eat a more WFPB diet than they did prior to Jumpstart. All either agreed or strongly agreed that they learned important information, were confident that they knew the best eating pattern for health, and gained the skills they needed to make changes. Although this was a small pilot program, it suggests that this model can be used to provide education and support for behavior change that will lead to improved health in a DHH community.
