I knew it was going to work because my sister in law lost 20 lbs in 2 months doing it and this was with drinking beer. It is the only "plan" that I felt great doing and with each loss of pounds and inches it gave me more incentive to stay LC. This is why I will always be LCing...maybe not as intensely as now during wieght-loss but definitely I will never go back to eating high-carb again!
