8. Calculate your BMR An easy way to find out your approximate BMR is to add a 0 to your body weight. EX) If you weigh 135 pounds…your BMR would be 1,350.

9. How many calories do you need? BMR + how active you are The more active you are, the more energy your body uses. The amount of energy needed for an activity also increases as body weight increases.
