Aging, Calorie Restriction and Calorie Restriction Mimetics

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...

The Benefits of Calorie Restriction and Calorie Restriction Mimetics as Related to the Eye.

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...

Calorie Restriction, Longevity and Cognitive Function

Calorie restriction and aging in nonhuman primates.

In the 75 years since the seminal observation of Clive McCay that restriction of calorie intake extends the lifespan of rats, a great deal has been learned about the effects of calorie restriction (CR; reduced intake of a nutritious diet) on aging in various short-lived animal models. Studies have demonstrated many beneficial effects of CR on health, the rate of aging, and longevity. Two prospe...

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...
