Generally speaking, what we want to advocate is exercise to lose weight. As long as this method persists, it doesn't need to cost too much. We always believe in advertisements such as drugs to lose weight, but most of them are not credible, and spending money does not have much effect. Maybe we will get some strange diseases. We also don't advocate diet control to lose weight, which is easy to hurt the body and will get fatter and fatter. Therefore, I strongly recommend that the landlord use exercise to lose weight, so as long as he persists, he will certainly succeed and will not spend too much money.
