Information on Yo-Yo Dieting

This is something I see in many people... Sigh... Hopefully by posting information here, people would be aware about it.

Yo-yo dieting, also known as weight cycling, is a repeated loss and gain of body weight due to excessive dieting. The term "yo-yo dieting" was coined by Kelly D. Brownell, Ph.D., at Yale University, in reference to the cyclical up-down motion of a yo-yo. In this process, the dieter is initially successful in the pursuit of weight loss but is unsuccessful in maintaining the loss long-term and begins to gain the weight back. The dieter then seeks to lose the regained weight, and the cycle begins again.
The reasons for yo-yo dieting are varied but often include embarking upon a diet that was initially too extreme. At first the dieter may experience elation at the thought of loss and pride of their rejection of food. Over time, however, the limits imposed by such extreme diets cause effects such as depression or fatigue that make the diet impossible to sustain. The dieter reverts to their old eating habits, and with the added emotional effects begins to rapidly regain weight.
This kind of diet is associated with extreme food deprivation as a substitute for good diet and exercise techniques. As a result, the dieter may experience loss of both muscle and body fat during the initial weight-loss phase (weight-bearing exercise is required to maintain muscle). After completing the diet, the dieter is likely to experience the body's famine response, leading to rapid weight gain of only fat. This is a dangerous fat-cycle that changes the body's fat to muscle ratio, one of the more important factors in health. -

Will yo-yo dieting have damaged my metabolism permanently?
Fortunately not! The idea that yo-yo dieting permanently lowers your metabolism has been relegated to the archives. However, if you've frequently crash dieted and severely restricted your calorie intake without exercising, it's likely you'll have a lot less muscle now compared with the very first time you dieted. As a consequence, it's likely your metabolism will also be lower so that you need fewer calories to maintain your current weight. This is because when you follow a very low calorie diet, you lose muscle as well as fat (see above). But when the weight goes back on, you usually only regain fat. This means, your metabolic rate is likely to have dropped a little every time you've dieted, making it slightly harder each time for you to lose weight. The good news is you can increase the amount of muscle you have by increasing the amount of exercise you do. This in turn will rev up your metabolism so that you can lose weight one final time on a slightly higher calorie intake than you've perhaps been used to. -

Bump to let more people know
HK, it is still bad in the long run. The healthiest way of losing fats is not dieting, but rather, a proper diet + sufficient exercises/movements
