Hello, if the elderly want to lose weight, they should first go to a regular hospital for a general examination. On the advice of the doctor, they are making a decision. Because the health of the elderly is more important, I personally think it is better to gain weight. If obesity really affects health, such as "three highs", I suggest you exercise more. If you have nothing to do, you might as well go for a walk and exercise in the park. If the elderly like drinking tea, it is also a way to lose weight. You can choose to drink a cup of slimming tea after a meal to eliminate greasy body.
