Eating fitness meals will really make you thin, because fitness meals are well matched. If you want to lose weight, diet conditioning is very important. Eat a balanced diet for three meals, eat more digestible and light fruits and vegetables, especially for dinner, and be sure to eat less. You can eat some crude fiber and low-fat food, but try not to eat any food after nine o'clock, which is not easy to digest and will also cause gastrointestinal discomfort.
