In terms of diet, you can eat some beef and eggs, because protein is the source of energy for muscles and proper fat, mainly carbohydrates such as rice, pasta, bread, some French fries, ice cream, peanuts and bananas. It won't be the same as usual when eating. You should eat more rice. Now, you have to eat two bowls. I'll get used to it at night, and add a little banana snack, which has more calories and is suitable for dessert. If you want to eat protein powder, you'd better add some honey at night, which can protect your kidneys and have a high-protein diet.
