Gaining lean muscle mass without adding body fat cannot be achieved naturally by throwing loads of calories into a diet plan or consuming every supplement in store without the nutritional knowledge. A person cannot starve themselves and expect to become ripped or lose only fat. There has been many studies over the years with many combinations of total calories and respective protein, carbohydrate and fat ratios. Two of the most effective formulas that give total daily calories are used in the Macronutrient Calculator. The first is used if an exact Body fat percentage is not known, the other more accurate calculates your total daily calories based on a person’s body fat percentage.

The Macronutrient Calculator will accurately calculate individuals different nutrient demands to optimize lean muscle growth. This is an extremely accurate formula calculated off body weight, body fat percentage and activity level.
