1. Drink yogurt in the morning and drink less soy products.
Don't eat pork, eat more fish, beef, mutton and so on.
3. Drink less water at night
4. Eat less and eat more vegetables when eating.
If you don't eat at night, eat apples on an empty stomach.
These points are actually very simple, just pay attention in daily life, but they are also personal. Being as fat as me is really great.
