This fat should mean strong body. First of all, don't be picky about food. But it doesn't mean you have to eat everything. Whole grains are indispensable. Eat more lean meat and ribs. Secondly, the diet should be regular. Four meals a day, good morning, full in the afternoon and less in the evening. It's also good to eat some supper properly. Early to bed and early to rise. Finally, we must strengthen our exercise. It is best to exercise for at least 40 minutes every morning. The above is for reference only.
