If you eat pure protein food, you won't gain weight. You can consider drinking protein powder, not milk, not cocoa powder, or you will be fat to death ~ ~

I suggest you eat normally in the morning, eat those low-fat or fat-free foods at noon, and try not to eat at night.

Eat yogurt and green tea powder in the morning. When you are hungry, you will usually eat konjac jelly, but it is more useful to eat less rice normally.
