Calories Calculator

The Calorie Calculator can be used to estimate the number of calories a person needs to consume each day. This calculator can also provide some simple guidelines for gaining or losing weight.

Calorie burn calculator is based on the 2011 Compendium of Phycalculation, thensical Activities, an authoritative list of the calories burned by 821 different activities including not only exercise, but daily activities like housecleaning—even sleeping.

The compendium works by assigning each activity a metabolic equivalent for task (MET) value. This number estimates how much energy the body uses during a specific activity. It varies based on activity, as well as intensity.

For example, a moderate-effort video workout combining cardio and resistance training (4 MET) burns fewer calories than a vigorous-effort video workout like those in FYR: Hannah Eden's 30-Day Fitness Program. The calculation then factors in your weight and the duration of the activity using this formula:

If you lose 500 Kcals a day, you would lose about 1lb of weight a week.

BMI Formula = [Weight (lbs) / Height (inches)²] x 703 or Weight (kg) / Height (m)² or [Weight (lbs) / Height (cm / 2.54)²] x 703
