Eat well in the morning, eat well at noon and eat less at night. In addition, you can drink a cup of milk vinegar (200ML milk, a spoonful of vinegar) after meals, then digest it properly and do exercise for 5 to 15 minutes. You can drink 2 cups of milk vinegar at night (try not to eat it at night), and you will get better after dinner. As long as you persist, you will soon see the effect.
