Hi M.Sten. Yes diet intake is around a strict 1650-1850 calories, 28,000 steps = around a burn of 1600 calories and my body functions takes care of the rest, making my intake on average minus 200-400 calories per day = weight loss. Try walking for 75 minutes see how many steps you make in that time, then push yourself a bit more each time. 10,000 steps can be done in that time. Good luck hope this info helps. Ps. My age is 48 yrs old and feeling fantastic. Cheers Steve.
