The landlord's situation is a bit like my friend. He doesn't want to lose weight at ordinary times, and it's too late to lose weight at critical times. There is no good way to lose weight quickly. As several people upstairs said, exercise is the best way, but visually the landlord is a little lazy and probably doesn't want to move. My suggestion is that you can try to lose weight with bitter gourd and apples. The essence of this method is that you can only eat apples or bitter gourd every day for three days. I wonder if the landlord can stand it!
