Hello, generally speaking, it's exactly what you said. The main reason is that the older you get, the slower your metabolism and the faster you grow with your children, regardless of your height and weight, while the weight of the elderly is very stable. If you don't get sick, there won't be much change. But that doesn't mean you can't lose weight when you are old. Old people need to persevere in losing weight. They can't eat a fat man in one bite. They should do it bit by bit through their usual living habits, such as controlling the intake of sugar and fat every day, doing a certain amount of exercise every day, and even walking. Stick to it for a few years and you will definitely get something.
