Ever asked yourself “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. The fact is that your correct weight is not determined through age. It basically concerns a number of factors like body fat mass, body frame, lean muscle mass and height. 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.
