Losing weight is not by eating, but by eating is unscientific. A reasonable diet and eating less and exercising more are the healthiest ways to lose weight.
Diet control: Have a full breakfast and try to eat sandwiches, bread and the like; Lunch and dinner should be halved; Can't eat supper; If you eat vegetables, don't eat greasy food. Try scalding the vegetables with boiling water. Drink 800 ml of water every day.
