Getting fat after maturity is basically the reason for the decline in physical fitness. When the body's metabolism slows down, fat begins to accumulate, so adults are generally fatter than when they were young.

I suggest that the best way for lazy people to lose weight is to eat as little or no dinner as possible, and only eat fruits or vegetables on an empty stomach when they are not working on weekends. After a long time, you may lose weight. The fundamental way is to exercise regularly, maintain the body and strengthen the physique. If the human body has a fast metabolism, it won't get fat.
