Alarcon et al. (1) recently demonstrated that b-cell insulin secretory dysfunction is rapidly restored by exposure of islets to low-normal glucose ex vivo in db/db mice. The authors allude to the potential clinical relevance for “transient b-cell rest” in type 2 diabetes (T2D). Could transient b-cell rest be accomplished by manipulating diet? Lim et al. (2) have shown that a very low-calorie di...

Background & Aims: Nonalcoholic steatohepatitis (NASH) is part of nonalcoholic fatty liver disease (NAFLD). No special medical treatment is known for this disease, and lifestyle modification is the best known method of treatment. We aimed to compare the effect of diet and aerobic exercise with that of diet alone on the quality of life of patients with NASH. Methods: In the present study, 25 pat...

BACKGROUND There have been few long-term follow-up studies of older adults who follow different dietary patterns. METHODS We cluster-analyzed data on dietary fat, fiber, protein, carbohydrate, and calorie consumption from the U.S. Cardiovascular Health Study (mean age=73), and examined the relationship of the dietary clusters to outcomes 10 years later. RESULTS The five clusters were named ...

The expression of the natriuretic peptide clearance receptor is abundant in human and rat adipose tissue, where it is specifically inhibited by fasting. In obese hypertensives, plasma atrial natriuretic peptide (ANP) levels were found to be lower than in obese normotensives. Therefore, the increased adipose mass might influence ANP levels and/or its biological activity. The aim of the present s...

Studies on rats maintained on low-protein-calorie diets during the lactation period show that food intake decreases. This process results in weight loss and a delay in litter development. The purpose of the present study was to determine the alterations in food intake, maternal weight and litter growth during lactation when dams were exposed to diets with different levels of protein and carbohy...

Enhancement of mammary tumor formation by dietary fat may be mediated via increased caloric intake. Three experiments were performed to study this relationship in 7,12-dimethyl-benz(a)anthracene (DMBA)-treated female Sprague-Dawley rats: (a) high- or low-fat isocaloric diets were fed in a crossover design; (b) low-fat, high-calorie and high-fat, low-calorie diets were fed in a crossover design;...

Objective: The present study aimed to determine the effects of diet of negative calorie foods (NCF) on weight, atherogenic lipids, and atherogenic ratio and compare its efficiency with diet of low calorie foods (LCF). Materials and Methods: In this randomized clinical trial, the participants were randomly selected from inactive overweight females (age 45-75 years) by parallel assignment were d...

BACKGROUND Studies of weight-control diets that are high in protein or low in glycemic index have reached varied conclusions, probably owing to the fact that the studies had insufficient power. METHODS We enrolled overweight adults from eight European countries who had lost at least 8% of their initial body weight with a 3.3-MJ (800-kcal) low-calorie diet. Participants were randomly assigned,...

BACKGROUND High-fat, low-carbohydrate diets are widely used for weight reduction, but they may also have detrimental effects via increased circulating free fatty acid concentrations. OBJECTIVE We tested whether raising plasma free fatty acids by using a high-fat, low-carbohydrate diet results in alterations in heart and brain in healthy subjects. DESIGN Men (n = 16) aged 22 ± 1 y (mean ± SE...

Background: The increase of calorie intake can the risk obesity and diabetes mellitus. One efforts to reduce is doing physical exercise. Types exercise that affect system female reproduction are not clearly defined. Purpose: To analyse effect moderate intensity continuous on FSH levels in rats exposed a high-calorie diet. Methods: Laboratory experimental was research with Randomized Post test o...
