I have gone from 19 1/2 stone in January 2009 to 14st 11lbs today, November 2009. Almost 5 stone. Just by using a reduced carbohydrate, low fat, low salt, low sugar and low GI/GL methods.
BMI gone from 38.1 (obese) to 28.9 (over weight). A little more to go, but so much more vitality, fitter, livelier. So much difference in such a short space of time.
