This balance can track six data: - Weight (the base) - The IMC (easy to calculate because the balance has asked us our size) - The percentage of body fat (which must fall if we want to lose weight) -the percentage of skeletal muscle (which should increase) - Resting metabolic rate (the number of calories that must be met to provide the energy required) - The visceral fat index (if the index is too high, it is quite possible that fat leads to medical complications) The balance can store the last set of measurements of four. The data seem reliable and consistent. We weighed barefoot, one catches the dial that takes arms extended vertically and wait a few seconds without moving for the measure. The manual is to keep as it includes all the tables that will enable us to set goals. If we take only our weight possible just as well. This balance is very useful to accompany a consequence regime. Increasing muscle mass is increase his energetic needs and thus lose weight without even changing his diet. In the flats, I still cite the use of the on / off button which I find quite tedious (and it lacks an automatic stop) and also the lazy / geek that I appreciate Bluetooth connectivity to monitor progress (or not progress)
