Calorie restriction means reducing average daily caloric intake below what is typical or habitual, without malnutrition or deprivation of essential nutrients. Calorie restriction has been linked to extended lifespan or delayed aging in models for aging that include yeast, nematodes, and rodents.
Cutting calories needs to include change. These changes can have a big impact on the number of calories take in:
*Skipping high-calorie, low-nutrition items
*Swapping high-calorie foods for lower calorie choices
*Cutting portion sizes
Animal studies have found health benefits in calorie restriction that include improved metabolism, longer life spans, and delayed onset of age-associated diseases. The metabolic regulatory effects of calorie restriction include attenuation of protein translation and improved glucose homeostasis. These metabolic mechanistic effects may underlie the observed increases in calorie restriction -mediated longevity.
Cutting calories too severely can lead to negative side effects like nutrient deficiencies and fatigue. Low calorie diets rarely work for long-term weight loss and can lead to weight cycling, which negatively affects overall health.
