Most people ask themselves, “How much should I weigh”? You might be having problems with your weight especially if a person your age is obviously thinner. Hence, you might be asking yourself If you’re starting to acquire more weight than necessary. Don’t panic yet. It’s not just your age that’s used as a basis for weight. It depends on different factors which include a person’s frame, height, lean muscles mass and body fat mass. Hence, if you are the same height and age with a person, that doesn’t mean that your weight should also be the same. Still, a body mass index is available if you want to get an exact number.
