Tighten your stomach with a belt, will it get smaller?
The landlord is very funny. No. If your trousers are too big, the belt is used to adjust the size. Just tightening your stomach is a waste of belts! Also, how can military training starve to death? Unless you don't eat or are picky about food, after all, you can't eat well at home, but you still have to eat to fill your stomach!
