actually being overweight and obese are different, you can be a muscle man and be overweight yet not obese, or a muscle women, you can be lean and yet be overweight, overweight is just being over the numbers they say you should be obesity is being over fat (fat to muscle ratio) that equals 20 percent or higher than you should be for good health,
of course those charts may say otherwise, but they list lean people as obese because they are large, but they are large not due to fat so the numbers are misleading, take the charts figures of what you should weight with a grain of salt.
