What is it?
Fat Free Mass is the total weight of the body minus the weight of any fat measured. This gives an indication of the water, bone, skin and internal organs as a combined weight. Fat-free mass refers to any body tissue that does not contain fat.
Why is it important?
Fat Free Mass has been given significant focus in studies of aging, as it is seen to decrease as early as 25 and almost all cases after 40. Decreases are associated with increased risk of falling and deceased quality of life.
During a weight loss programme aim to maintain fat free mass, meaning that the weight you lose is from Fat Mass.
