Effect of dietary fat, carbohydrate, and protein on branched-chain amino acid catabolism during caloric restriction.
To assess the effect of each dietary caloric source on the catabolism of branched-chain amino acids, we investigated the rate of leucine oxidation before and after obese volunteers consumed one of the following diets for one week: (a) starvation, (b) 300 or 500 cal of fat/d, (c) 300 or 500 cal of carbohydrate/d, (d) 300 or 500 cal of protein/d, (e) a mixture of carbohydrate (300 cal/d) and fat ...
متن کاملDietary restriction with and without caloric restriction for healthy aging
Caloric restriction is the most effective and reproducible dietary intervention known to regulate aging and increase the healthy lifespan in various model organisms, ranging from the unicellular yeast to worms, flies, rodents, and primates. However, caloric restriction, which in most cases entails a 20-40% reduction of food consumption relative to normal intake, is a severe intervention that re...
متن کاملDietary fat and carbohydrates differentially alter insulin sensitivity during caloric restriction.
BACKGROUND & AIMS We determined the effects of acute and chronic calorie restriction with either a low-fat, high-carbohydrate (HC) diet or a low-carbohydrate (LC) diet on hepatic and skeletal muscle insulin sensitivity. METHODS Twenty-two obese subjects (body mass index, 36.5 +/- 0.8 kg/m2) were randomized to an HC (>180 g/day) or LC (<50 g/day) energy-deficit diet. A euglycemic-hyperinsuline...
متن کاملDietary Protein to Carbohydrate Ratio and Caloric Restriction: Comparing Metabolic Outcomes in Mice.
Both caloric restriction (CR) and low-protein, high-carbohydrate (LPHC) ad-libitum-fed diets increase lifespan and improve metabolic parameters such as insulin, glucose, and blood lipids. Severe CR, however, is unsustainable for most people; therefore, it is important to determine whether manipulating macronutrient ratios in ad-libitum-fed conditions can generate similar health outcomes. We pre...
متن کاملCaloric restriction in humans.
Studies on mice and rats have demonstrated that calorie restriction (CR) slows primary aging, has a protective effect against secondary aging, and markedly decreases the incidence of malignancies. However, the only way to determine whether CR "works" in humans is to conduct studies on people. Such studies are difficult to perform in free-living people. While research on CR in humans is still at...
