Chronic Dieters who lost 10% body weight and then gained it back, increased heart risk by 30%. Yo-yo dieting or weight cycling makes it harder to lose weight permanently and is more dangerous to health.
Desire for fatty-foods is actually increased by weight-loss/weight-gain cycle. People, who lost weight rapidly, due to the low calorie diet, always craved for more fat in their diet.
Yo-yo dieters have repeated bouts of weight-loss and weight-gain. And if weight is regained, they usually regain more fat and less muscle.
After weight cycling, body fat is redistributed in the abdomen from the thighs, hips and buttocks.
Your Basal Metabolic Rate (BMR) slows down when you lose weight by cutting down on calories. As a result the body burns fewer calories to conserve energy.
Additional weight-loss thereby becomes almost impossible and rebound weight-gain is inevitable.
As you reduce your calorie intake, the enzyme LPL (Lipoprotein Lipase) makes the body more efficient and convenient to store fat.
The obese women who lost weight through dieting (when compared to the normal weight women) needed fewer calories to maintain their weight.
Female dieters who showed repeated weight loss and weight-gain cycle, increased risk of sudden death from heart attack.
Yo-yo dieting also harms the immune system. Therefore a sensible approach to dieting is incorporating healthy eating habits, combined with a regular exercise program of walking.
