And don't lie down after eating! No eating, no watching TV and so on.
In short, just eat 7 points full ~ don't eat hard and watch delicious food ~! Accumulate a full meal
Go to bed early, don't stay up late! Eat at 5-6 pm on time, and then go out for a walk between 1-2 hours and 1 hour! Or do some light sports, such as skipping rope, badminton and so on!
The most important thing is "don't be lazy"
