But you may also calculate your fat-free weight on your own using this formula: fat free weight (FFMI) = (Lean / 2.2) / ((Height in ft x 12.0 + in) x 0.0254)2 x 2.20462. — so that if you repeat meals, you don’t have to repeat all the work of entering it in. However, a percentage of adipose tissue is essential for the proper functioning of our body, since it is precisely here that the reserve energy is stored which the body can draw on in case of need.
