I'm on day 7, so at the minute my diet needs to be my every thought, but I can appreciate as you go along it gets hard consuming so much time thinking about it. If I stick to this diet for the long haul, then I worry what it will be like returning to normality. The fact they suggest 1500kcals as maintenance, rather than the usual 2000 kcals a day, suggests to me, you never really do return to normal. But then I guess if we were 'normal' then we wouldn't have weight issues.
