Just thought I would chip in here.

I have lost approx 11% bodyfat over 2 half months eating between 1700 & 1900 cals a day and lost about 4 pounds - I was aiming to stay as close to 12 stone as possible (my bodyfat is now roughly 12%), this gives me enough to train between 1 to 2 hors a day 6 days a week - I take one random day off a week and vary my calories as Thursday and Sunday I get a sleep in so eat slightly less (i.e 1700 cals) - this seems to shock my body a bit and keeps the fat loss going (and my body from getting used to the eating times and going stale) - for the record it took about 6 weeks for my body to react and I would suggest from my experience and from my mates who are personal trainers and professional cage fighters that they all say that if you start a "diet/new eating habits" give it 6 weeks - it was very weird but I saw almost no change and then around the 6 week mark bang, I lost loadsa fat over the next couple of weeks and I am now at a steady rate and think the extra 4 % I am gunning for will happen the same - just my opinion tho .
.....it seemed that my bodyfat was deep ab fat and it took a while for this inner fat to go even tho my diet and exercise got ramped up roughly 6 weeks earlier.
