It's best to eat some lean meat for lunch, such as chicken breast, beef, fish and shrimp, add some fresh vegetables and fruits, or eat some stir-fry properly, but don't put too much oil. After all, you have eaten nuts for breakfast, and basically the body's daily fat needs have reached the standard.
So at noon, eat less fat, eat more fruits and vegetables, and eat some staple foods, such as rice, noodles and steamed bread.
