Quoting Sweet lullaby:" Did you gain anything back after you stopped?"
When I did it I was about 120, dropped to 115 by the end of the week (Maybe too much info for you but I smurf a lot) and a few weeks later with limited gym time settled into about 118.
I figure I'll do it again in a few weeks (so about 2 months after the first one). If I loose more weight, cool. If I don't, no biggie. If I gain any, then I just up my time at the gym.
Weight isn't super important to me - I'm usually any where between 110 and 125 during the year (summer vs. winter time). My goal is just to maintain a healthy body and that means putting healthy things into them.
I could just "cut dairy and wheats" out of my diet for a few days and eat the veggies and have it be "not a fad", but when I say I juice them I get dirty looks. There's not really a difference to me, it's what I normally eat any way. It's just a different way of getting more of the good and less of the smurf into me for a few days, then going back to how I normally eat when I'm done.
