RESEARCH DESIGN AND METHODS—Twenty-two obese women followed a dietary intervention program composed of an energy restriction phase with a 4-week very-low-calorie diet and a weight stabilization period composed of a 2-month low-calorie diet followed by 3–4 months of a weight maintenance diet. At each time point, a euglycemic-hyperinsulinemic clamp and subcutaneous adipose tissue biopsies were pe...

Easy access to high-energy food has been linked to high rates of obesity in the world. Understanding the way that access to palatable (high fat or high calorie) food can lead to overconsumption is essential for both preventing and treating obesity. Although the body of studies focused on the effects of high energy diets is growing, our understanding of how different factors contribute to food c...

Calorie restriction is a common strategy for weight loss and management. Consumption of food and nutrients stimulates diet-induced thermogenesis (DIT), as well as pancreatic and gastrointestinal hormone secretion that may regulate energy metabolism. Yet, little is known about the impact of hypocaloric diets on energy metabolism-related parameters. In this study, we assessed the effects of hypoc...

This study was designed to determine the genotoxicity of a supraphysiological dose of triiodothyronine (T3) in both obese and calorie-restricted obese animals. Fifty male Wistar rats were randomly assigned to one of the two following groups: control (C; n = 10) and obese (OB; n = 40). The C group received standard food, whereas the OB group was fed a hypercaloric diet for 20 weeks. After this p...

background: overweight and obesity increasing world wide because of changing life style and dietary habits. diet therapy plays an important role to prevent obesity outcomes. the aim of this study was determining the effects of diet therapy on weight reduction and fitness. methods: a clinical trial study was conducted using convenient sampling method and 216 subjects (190 female and 26 male) wer...

The growth and development of 32 cebus monkeys were studied during a period of insult in nutritional or rearing conditions and after rehabilitation. Eight experimental groups of four animals each were subjected to one of four diets--control, protein restricted, calorie restricted, and protein-calorie restricted, and one of two rearing conditions-partial isolation or a comparatively enriched con...

This study was conducted to evaluate whether the composition of carbohydrate or fat diet affects insulin resistance by measuring the muscle glucose transport rate. Both high-sucrose and high-starch diet with or without high-fat decreased insulin-stimulated glucose transport, but there were no significant differences among groups. Calorie intake in both high-sucrose and high-starch diet groups w...

BACKGROUND Nonpharmacological interventions have been efficacious to control blood pressure (BP) in clinical trials, but their long-term effectiveness in clinical practice was still not documented. METHODS This is a prospective cohort study of 825 patients who received repeated nonpharmacological recommendations to treat hypertension. The outcomes were BP change and rate of BP control by patt...

AIM To investigate the synergistic hepato-protective properties of curcumin and vitamin E in an Hfe-/- high calorie diet model of steatohepatitis. METHODS Hfe-/- C57BL/6J mice were fed either a high calorie diet or a high calorie diet with 1 mg/g curcumin; 1.5 mg/g vitamin E; or combination of 1 mg/g curcumin + 1.5 mg/g vitamin E for 20 wk. Serum and liver tissue were collected at the complet...
