Calorie Restriction Diet Plans: Are They Healthy?

Claimed Health Benefits

The claimed health benefits of calorie restriction diets extend far beyond weight loss. Proponents of these approaches assert these diets can improve cardiovascular health and even extend lifespan. Although more research is needed, studies in animals suggest engaging in calorie restriction extends lifespan by as much as fifty percent. Research conducted in primates also suggests restriction could reduce a dieter's risk of cancer and age-related memory issues. Studies in humans have shown calorie restriction improves markers of cardiovascular health, providing reductions in cholesterol, blood pressure, waist circumference, and blood sugar. A study of diabetes patients published in 2017 found caloric restriction was effective in reducing blood sugar and blood pressure for this patient population, and the subjects also had reductions in inflammatory markers. Additional research has shown calorie restriction can reduce oxidative stress, and patients who follow this dietary approach for several months have also reported increased mood and reduced feelings of stress and tension.
