Recommend muscle-building powder because you are relatively thin. Protein powder can also be used
But creatine is not suitable for you
If it refers to diet, the first step is to change to small meals with frequent meals
Of course, dinner can be three meals
But you can have a late-night snack in the evening. It’s OK to boil two eggs in the afternoon to supplement your nutrition.
At least 4 meals a day
