Calorie Restriction, Longevity and Cognitive Function

Calorie Restriction

Calorie restriction, or caloric restriction (CR), is a dietary regimen thought to improve health and slow the aging process in some animals and fungi by limiting dietary energy intake below the average needs. CR is the only dietary intervention which has been documented to increase both the median and maximum lifespan in a variety of species, among them rodents, yeast, fishes and dogs. The life...

Calorie restriction and sirtuins revisited.

Calorie or dietary restriction (CR) has attracted attention because it is the oldest and most robust way to extend rodent life span. The idea that the nutrient sensors, termed sirtuins, might mediate effects of CR was proposed 13 years ago and has been challenged in the intervening years. This review addresses these challenges and draws from a great body of new data in the sirtuin field that sh...

Calorie restriction and cancer prevention: a mechanistic perspective

Calorie restriction (CR) is one of the most potent broadly acting dietary interventions for inducing weight loss and for inhibiting cancer in experimental models. Translation of the mechanistic lessons learned from research on CR to cancer prevention strategies in human beings is important given the high prevalence of excess energy intake, obesity, and metabolic syndrome in many parts of the wo...

Aging, adiposity, and calorie restriction.

CONTEXT Excessive calorie intake and subsequent obesity increases the risk of developing chronic disease and decreases life expectancy. In rodent models, calorie restriction with adequate nutrient intake decreases the risk of developing chronic disease and extends maximum life span. OBJECTIVE To evaluate the physiological and clinical implications of calorie restriction with adequate nutrient...
