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.

Risks Of Calorie Restriction

Patients who practice calorie restriction diets may wish to do so under medical supervision, and calorie restriction is not usually recommended for individuals over fifty years old or for those who have chronic health conditions that require medication. Some of the potential risks of calorie restriction include heart rhythm abnormalities, nutrient deficiencies, liver or kidney damage, and weakening of the bones. Studies of patients who were heavily involved in sports such as gymnastics or taekwondo while following calorie restriction plans concluded that such patients had decreased immune system function and an increased risk of infection. The rapid weight loss that often results from calorie restriction could elevate an individual's risk of developing gallstones. Patients who experience pain in the upper right part of the abdomen while on a calorie restriction program should see a doctor as soon as possible.
