Best wishes with it. The BEST thing for those of us starting at over 300 lbs is that the weight falls off so much quicker! :8855:
You can see from my sig below I've lost two stone in two weeks + it's not just all water -- real fat has gone. My measurements are about 3" less and my old size 30 / 32 trousers fell off yesterday (LOL!).
The calorie deficit that the LL programme induces works *sooooo* much to our favour because a body that weighs over 300 lbs actually requires more than 3,000 cals a day to keep it that size -- therefore we can lose (easily) one pound a day for the first few weeks !!!
