Here are a few health and nutrition calculators to help you make sense of your body composition, what you should weigh, how much you should eat, and other delightful facts and figures applicable to your fat or fit body. Try try some or all of them to see how each one differs from the next. Some take more variables into consideration than others. I like that.
Good Luck!
