If you gain muscle, you can control your weight at 175g, so you can eat less and eat more meals, 5 -6 meals a day. In fact, you can divide the usual three meals into six meals, and you can eat less and add more appropriately. After all, to grow muscles, you must ensure that you get enough protein and carbohydrates. I will give you a secret recipe according to your own situation.

Breakfast: 4 egg whites or a spoonful of protein powder 1 egg white+a small bag of milk (you can add some oats) +3 slices of whole wheat bread+a plate of beef (eat as much egg whites as possible)+a big apple or banana.

Morning meal: milk powder or cereal+fruit

Noon: staple food (mainly rice, steamed bread and coarse grains)+a plate of vegetables (raw cucumbers, tomatoes and miscellaneous vegetables)+stir-fry (try to eat cooked food with less oil)+lean meat (if possible) 80% full.

Lunch: vegetables+fruits (bananas, apples, cucumbers, etc. )

After exercise (protein powder, no condition to drink milk and eat whole wheat bread)

Dinner: a small amount of staple food+vegetables+stir-fry (stew or cooked food, stir-fry without oil)+fruit.

Snack: If you don't eat it, it's just an apple or banana and a small bag of milk.

All right, don't eat too much. Don't fry it.
