I have never tried it myself. But many people who have used this machine complain that it can't see the effect and will rebound more. Buy carefully. After all, passive weight loss will not have a good effect. I am fat, too. Eat normally, but really eat less. The amount of exercise every day should be guaranteed. It lasted nearly two months. Now I'm back to normal diet, and I don't have time to exercise or anything. I'm lazy. Never gain weight again. Just eat less and exercise more. Stick to it, and you can do it.
