I have done WW in the past (repeatedly) but gave up my attempts a while back as it always ended up with me binging big time after weigh in, spending the rest of the week cutting back and exercising like crazy, it was awful.
Anyway back to the point of your thread (excuse the pun!), I have been calorie counting recently and find it very hard not to tot up the calories in a meal whilst I'm eating it on SW, so I guess that's a similar thing. I'm trying to ignore this and am hoping it will wear off soon. It'll help if I lose a good amount at my first week weigh in because then I'll trust the diet a bit more.
You're not alone, but don't pay any attention to the points. Your body does treat different types of calories differently, and there was an article in New Scientist recently about how anything up to 20-40% of calories in high fibre things like fruit, wholegrains and pulses get eliminated as waste rather than utilised by the body. Whilst I don't know how accurate this is, it does go to show how little we actually know about all this and that are bodies are not calculators, so it really is trial and error to find what works for an individual.
Sorry for the waffle and hope it helps...
