We must control our diet. Even people who don't exercise should control their diet to some extent. I used to be a lucky man. I am a very thin person, no matter what I eat, I won't get fat. In order to make myself look stronger, I began to exercise and gain weight with my diet, but my diet was not indiscriminate. I can't eat a lot of junk food or greasy food. It's not good for your health either. Generally, I will supplement my nutrition by eating some protein powder and the like. Therefore, you can't eat and drink casually in fitness. Nutrition collocation is the most important.
