Fighting the battle of the bulge can range from following a sensible diet to making ill-guided efforts that may include extreme or even downright risky behaviors. Some tactics are unlikely to cause harm because they cannot be sustained long enough to do damage. But others can have serious health consequences.
Michelle May, MD, an Arizona-based weight management doctor, says, “People get so focused on weight loss they are willing to do unproven and potentially dangerous things that can backfire and cause serious health problems.”
Starvation, Fasting, or Very Low-Calorie Diets
Severely slashing calories leads to weight loss, but the lost weight includes precious muscle mass and poses health risks -- and most people end up regaining the weight plus extra pounds.
“Rapid weight loss by critical calorie restriction," May, the author of Eat What You Love and Love What You Eat, says, "causes water, some fat, and muscle loss, which ultimately decreases metabolism so the body needs fewer calories to survive.” It also causes a shift toward a higher percentage of body fat, which increases the risk for metabolic syndrome and type 2 diabetes.
Don’t cut calories below 1,200 per day. Otherwise, you will struggle to meet nutrient needs, fuel your activity, and satisfy your hunger. Keep in mind that when you lose weight quickly, you tend to pack it back on with more fat and less muscle, which lowers your metabolism and calorie needs even more.
