Good morning Marvellous - I have been wondering about the calorie counts, am reasonably convinced that 20-50 calories here or there is not going to make a significant difference, even Dr M reckons that people will have high & low days so taking that into account, some marginal variation is not going to be a deal breaker, after all a body can't actually count calories.
Our age, hormones, activity levels, time of month, sleep patterns etc etc will also have an impact on our use of energy, I have had days when I have strayed mightily, (wine..) only to find no difference on the scales, other times I have eaten marginally under 800 calories for 5 days & put on a lb!
I grill or pan-frying fish, chicken, the occasional chop etc & eat lots of above the ground veggies, slapping on some spice paste for flavour if I can't be bothered to follow a recipe from the book; I am in this for the long-term though & do appreciate that my objectives are possibly different from other people's.
10.2lbs sounds pretty darned good to me though, am well impressed with your results!
