Really no weight loss effect! It will only make you feel tight, eat less and look thin. All this is an illusion! Tightening will only reduce the space of your internal organs. After a long time, your internal organs will be uncomfortable. It may still cause harm! If you want to lose weight, you should eat less and exercise more, so the consumption is greater than the intake, in order to consume the body fat and really lose weight! I wish you health and happiness!
