I really hope you don't mind me saying this But PLEASE try not to be obsessive about the precise calories in everything.
You haven't offended me at all jan, if anything, you've really helped. I know I can be very obsessive with weight, the fear of gaining weight again is so strong and it's going to take me a while to feel comfortable.
I remember being obsessive. In fact, I was for quite a long time. Never went to 2 decimal points, or even 1 come to that, but only because the software I used didn't compute that way...or I probably would have
I was very strict with my calories going up the plans though, and continued to count well after the 'diet'. Like you Yasmine, I was frightened of going wrong. I knew I couldn't diet again, so I had to get it right. And besides, I had relaxed too much in the past and it hadn't worked. Could take the risk this time.
Having said that, there is a fine line, especially when it comes to weight. You need to be logical.
With cambridge, the plans are pretty much set out..gradually increasing both cals and carbs over a period of about 10 weeks until you come off the diet. Eat this or that for breakfast, this or that for lunch. etc. Idiot proof
Of course, me being me, still mananged to fall a couple of times, but I have a sort of guideline.
Regardless of what the scales say, cheat on a plan and you stay on that one without moving up for another week. Do the plan 100% and you move up regardless of what the scales say.
But, there is no one size fits all.
Just remember that it takes approx 3,500 cals over maintenance cals to put on a pound of fat and you wont go far wrong.
