I haven't heard of it. Diet pills are deceptive. They feel that eating them is not to lose weight, as if they are fasting. I don't want to eat anything after eating, but I can lose weight without eating. That's what diet pills do. It is a lie. 1. Strictly observe and develop the eating habit of "eat well early, eat well at noon and eat less at night". 2. Keep walking for more than half an hour after dinner. 3, do not eat sweets 4, chew slowly. You can lose weight. I wish you success in losing weight.
