OBJECTIVEdImpaired insulin sensitivity increases the risk of cardiovascular disease. Although calorie restriction and weight loss increase insulin sensitivity, the effects of modifying macronutrient composition on insulin sensitivity are uncertain. The purpose of this study is to determine the effects on insulin sensitivity of a carbohydrate-rich diet (CARB; similar to the Dietary Approaches to...

A 33 year old man presented with biliary colic and transient obstructive jaundice. In the 4 weeks preceding admission he had been taking a very low calorie diet (the Cambridge Diet) and celebrated achieving his target weight with a fatty meal on the morning of admission. An ultrasound of the gallbladder suggested biliary sludge. We suggest that he developed the biliary sludge as a consequence o...

Maintenance of weight loss remains an obstacle in successful treatment of obese individuals. The long term impact of calorie restriction on adipose tissue biology is poorly characterized. Molecular and lipid markers of these processes may provide wider understanding in the mechanisms underlying weight control. We aimed at identifying relevant relationship between clinical traits, clusters of ge...

We report the effects of a Mediterranean-style diet, with or without calorie restriction, on biomarkers of aging and oxidative stress in overweight men. 192 men were randomly assigned to either a Mediterranean-style diet or a conventional diet. The intervention program was based on implementation of a Mediterranean dietary pattern in the overweight group (MED diet group), associated with calori...

Calorie restriction has been the subject of research and studies for years. Although calorie is a broad definition; way, time, amount situations are very important. While restricting, carbohydrate, fat protein balances should be well evaluated. However, this shows various positive effects when done under suitable conditions without causing malnutrition. With restriction, production free radical...

Introduction: Fasting, like Islamic Ramadan Fasting, has been associated with health benefits. Islamic Ramadan fasting, a form of caloric restriction (CR) or alternate day fasting that. Studies suggest a comparable effect of ADF and caloric restriction. Despite the fact that fasting can be considered as a form of dietary restriction, fasters tend to have difficulty to reduce their food intake d...

The effects of calorie restriction without malnutrition seem to possess many beneficial effects in numerous disease states. Recently, studies related to calorie restriction mimetics that biochemically mimic the effects of calorie restriction are also becoming increasingly popular. Both calorie restriction and calorie restriction mimetics trigger an adaptive response reminiscent of mild-stress o...

Aging is associated with protein damage and imbalance in redox status in a variety of cells and tissues, yet little is known about the extent of age-related oxidative stress in the peripheral nervous system. Previously, we showed a drastic decline in the expression of glial and neuronal proteins in myelinated peripheral nerves with age, which is significantly ameliorated by lifelong calorie res...
