A person must exercise and eat the right kinds of food to lose weight. This is common sense. People who don’t want to exercise think that dieting is an alternative and the dieting industries only confirm this wrong belief. Diet industries only want to make money. This is obvious. And what will they do to make money. Anything. This includes blatant lies about dieting itself and their products.
With dieting people first go into starvation mode and then depression mode. Dieting causes weakness in the body and a person only loses fat to a certain extent. After that they start losing muscle tissue. One other thing is that when people starve themselves they will eat much more than they usually do, because they haven’t eaten for so long.
Exercising and eating the right kinds of food is enough. There is no reason to destroy oneself through dieting.
