BMR Health Calculator 1.0

Basal Metabolic Rate is the minimal caloric requirement needed to sustain life in a resting individual. Therefore your Basal Metabolic Rate is the number of calories youd burn if you slept all day.

Activity Multiplier

Sedentary = BMR X 1.2 (little or no exercise, desk job)
Lightly active = BMR X 1.375 (light exercise/sports 1-3 days/wk)
Mod. active = BMR X 1.55 (moderate exercise/sports 3-5 days/wk)
Very active = BMR X 1.725 (hard exercise/sports 6-7 days/wk)
Extr. active = BMR X 1.9 (hard daily exercise/sports & physical job or 2X day training, i.e marathon, contest etc.)
Now that you know your BMR and TDEE, should you decide to lose, gain or maintain your current weight, you just have to adjust your calorie intake accordingly.
