Abstract
BACKGROUND & AIMS COVID-19 is a respiratory syndrome caused by SARS-CoV-2. In the absence of effective treatment and vaccines, social distance (SD) is essential to reduce the spread of the virus. However, SD generates several behavioral changes, especially in psychological (i.e., emotions and depressive symptoms) and lifestyle-related parameters (i.e., diet, physical activity, and sleep), and the aged people could be more susceptible to COVID-19 SD-related effects (i.e., loneliness, stress, fear, concerns about life, etc.). As such, we aimed to explore the relationship between lifestyle- (physical exercise practice and sleep quality) and psychological-related factors with the dietary practices derived from the Brazilian National Food Guide of older adult during the COVID-19 SD. METHODS A web-based survey was conducted in São Paulo, Brazil. Data were collected between August and December 2020 (a period of social isolation due to the COVID-19 pandemic). The questions were extracted from validated questionnaires to verify dietary practices (score of adhesion to the food guide for the Brazilian population), sleep quality (by Pittsburgh questionnaire), emotional food-related dimensions (by Three-factor Eating Questionnaire), and depression symptoms (by Beck's questionnaire). RESULTS Results were from 229 aged people (mean age 66.5 ± 6.02 years old; mean BMI 27.5 ± 4.32 kg/m2; mean sleep duration 8.23 ± 1.41 h; Pittsburg sleep quality score 6.55 ± 4.83; dietary practice score 42.5 ± 6.47). In the adjusted-linear regression model, we verified that physical exercise practice at home (β = 2.179; 95% CI: 0.599 to 3.758; p = 0.007) during COVID-19 SD was positively associated with better dietary practices in aged people. In contrast, emotional eating was negatively associated with dietary practices (β = -0.051; 95% CI: -0.092 to - 0.009; p = 0.015). CONCLUSION We conclude that in aged people, physical exercise practice at home during COVID-19 SD was positively associated with better dietary practices, while emotional eating was negatively associated.

Young, healthy males and females present cardiometabolic protection against the detrimental effects of a 7-day high-fat high-calorie diet. Eur J Nutr 2020; 60:1605-1617. [PMID: 32789769 PMCID: PMC7987629 DOI: 10.1007/s00394-020-02357-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Accepted: 08/03/2020] [Indexed: 01/19/2023]
Abstract
PURPOSE High-fat, high-calorie (HFHC) diets have been used as a model to investigate lipid-induced insulin resistance. Short-term HFHC diets reduce insulin sensitivity in young healthy males, but to date, no study has directly compared males and females to elucidate sex-specific differences in the effects of a HFHC diet on functional metabolic and cardiovascular outcomes. METHODS Eleven males (24 ± 4 years; BMI 23 ± 2 kg.m-2; V̇O2 peak 62.3 ± 8.7 ml.min-1.kg-1FFM) were matched to 10 females (25 ± 4 years; BMI 23 ± 2 kg.m-2; V̇O2 peak 58.2 ± 8.2 ml.min-1.kg-1FFM). Insulin sensitivity, measured via oral glucose tolerance test, metabolic flexibility, arterial stiffness, body composition and blood lipids and liver enzymes were measured before and after 7 days of a high-fat (65% energy) high-calorie (+ 50% kcal) diet. RESULTS The HFHC diet did not change measures of insulin sensitivity, metabolic flexibility or arterial stiffness in either sex. There was a trend towards increased total body fat mass (kg) after the HFHC diet (+ 1.8% and + 2.3% for males and females, respectively; P = 0.056). In contrast to females, males had a significant increase in trunk to leg fat mass ratio (+ 5.1%; P = 0.005). CONCLUSION Lean, healthy young males and females appear to be protected from the negative cardio-metabolic effects of a 7-day HFHC diet. Future research should use a prolonged positive energy balance achieved via increased energy intake and reduced energy expenditure to exacerbate negative metabolic and cardiovascular functional outcomes to determine whether sex-specific differences exist under more metabolically challenging conditions.

Abstract
Increased myocardial partitioning of dietary fatty acids (DFA) and decreased left ventricular (LV) function is associated with insulin resistance in prediabetes. We hypothesized that enhanced myocardial DFA partitioning and reduced LV function might be induced concomitantly with reduced insulin sensitivity upon a 7-day hypercaloric (+50% in caloric intake), high-saturated fat (~11%energy), and simple carbohydrates (~54%energy) diet (HIGHCAL) versus an isocaloric diet (ISOCAL) with a moderate amount of saturated fat (~8%energy) and carbohydrates (~50%energy). Thirteen healthy subjects (7 men/6 women) underwent HIGHCAL versus ISOCAL in a randomized crossover design, with organ-specific DFA partitioning and LV function measured using the oral 14(R,S)-[18F]fluoro-6-thia-heptadecanoic acid and [11C]acetate positron emission tomography methods at the end of both interventions. HIGHCAL induced a decrease in insulin sensitivity indexes with no significant change in body composition. HIGHCAL led to increased subcutaneous abdominal (+4.2 ± 1.6%, P < 0.04) and thigh (+2.4 ± 1.2%, P < 0.08) adipose tissue storage and reduced cardiac (-0.31 ± 0.11 mean standard uptake value [(SUV), P < 0.03] and skeletal muscle (-0.17 ± 0.08 SUV, P < 0.05) DFA partitioning without change in LV function. We conclude that early increase in adipose tissue DFA storage protects the heart and skeletal muscles from potential deleterious effects of DFA.

Abstract
BACKGROUND Diabetic nephropathy (DN) is a potentially fatal complication of diabetes mellitus. While lifestyle changes can reduce diabetes risk, it is unclear whether improved lifestyle can slow or reverse DN progression. This study evaluated whether an intensive lifestyle intervention (IL-I) targeting weight loss and inflammation through increased physical activity and reduced caloric intake can delay DN progression. MATERIAL AND METHODS Patients were randomly divided into 2 groups. Both groups received diet and exercise guidelines, but one (IL-I) received more frequent external support than the other (control). We compared markers of metabolic and cardiovascular health, redox status, inflammation, and renal function between groups at 3 and 6 months. Metabolic and cardiovascular metrics included BMI, blood pressure, blood glycosylated hemoglobin (HbA1c), and serum HDL-cholesterol. Redox status was evaluated by serum superoxide dismutase (SOD) and the lipid oxidation product malondialdehyde (MDA), while inflammation was assessed by serum concentrations of IL-6 and TNF-alpha. Renal function was assessed by urine/serum 8-OHdG, albumin: creatinine ratio (ACR), and the renal fibrosis marker TGF-ß1. RESULTS Both groups demonstrated initial BMI reduction, lower HbA1c, and higher HDL-cholesterol, but changes were significantly larger in the IL-I group at 6 months. Blood pressure at 6 months was reduced only in the IL-I group. The IL-I group also achieved a greater sustained SOD increase and MDA reduction. Finally, only the IL-I group demonstrated significant reductions in urine ACR, serum/urine 8-OHdG, and plasma TGF-ß1. These indicators deteriorated after IL-I was stopped. CONCLUSIONS Lifestyle changes including exercise and diet can delay renal damage and promote improvement from DN.

Abstract
The aim of this review is to discuss the physiology of energy homeostasis (EH), which is a debated concept. Thus, we will see that the set-point theory is highly challenged and that other models integrating an anticipative component, such as energy allostasis, seem more relevant to experimental reports and life preservation. Moreover, the current obesity epidemic suggests that EH is poorly efficient in the modern human dietary environment. Non-homeostatic phenomena linked to hedonism and reward seem to profoundly impair EH. In this review, the apparent failed homeostatic responses to energy challenges such as exercise, cafeteria diet, overfeeding and diet-induced weight loss, as well as their putative determinants, are analyzed to highlight the mechanisms of EH. Then, the hormonal, neuronal, and metabolic factors of energy intake or energy expenditure are briefly presented. Last, this review focuses on the contributions of two of the most pivotal and often overlooked determinants of EH: the availability of endogenous energy and the pattern of energy intake. A glucoadipostatic loop model is finally proposed to link energy stored in adipose tissue to EH through changes in eating behavior via leptin and sympathetic nervous system activity.
