Replacing two cups of boiled water with a cup of honey water or a banana (eat these before breakfast) can moisten the intestines.
Lunch, eat less, you can eat more vegetables and less meat.
Dinner, it is best not to eat staple food, because there is little exercise at night, eating staple food is easy to get fat, and don't eat too much at dinner, just eat 7 or 8 minutes full. Then you can eat some fruit properly.
If you don't like sports, I suggest you go out for a walk after dinner every day. This is a good way to exercise.
Stay away from desserts, fried foods and some high-fat fast food.
And I think it's best not to fast and eat diet products, which is bad for your health.
I hope my answer is helpful to you ~
