If you want to eat well and be nutritious, you can read some cookbooks or small videos and learn slowly.
Don't rush for success, learn to make some simple snacks first, because midnight snack is not suitable for big fish and big meat, and any greasy and high-sugar food is not suitable for eating at night.
You can learn from friends around you and make some digestible porridge with simple snacks.
Because there are few activities in the evening, friends who are prone to gain weight need to be careful not to eat high-calorie, high-sugar and high-fat foods.
In short, if you want to learn to cook, you can find some cooking videos on Huadong Menu Network, learn to cook with friends around you, and also have cooking training classes.
