If I don't eat breakfast, I often get gallstones. I hope to get rid of this bad habit. I can eat less, but I can't help eating. Exercise for more than half an hour before you start to consume fat. Jogging for an hour and drinking a little black coffee half an hour before running will help burn fat. You can have a cup of yogurt for dinner. Don't eat snacks every day, fruit doesn't count. It takes more than half a year, preferably one year, to lose weight, because cells have memories, and it is easy to bounce back to their original appearance in a short time.
