Actually barring some metabolic disorder, calories in calories out IS correct. Not only is it correct, I find that bodies are quite mechanical in that nature. I wrote about my experience losing weight and gaining abs a couple of years ago (complete with statistical analyses of what matters and what does not): http://blog.chewxy.com/2015/12/02/holy-crap-ive-got-abs/#3500_to_a_Pound http://blog.chewxy.com/2015/12/02/holy-crap-ive-got-abs/#350... I've since maintained (and gained more visible abs :D ) with careful tracking on MyFitnessPal. I also find that if I do not track and weigh the food I eat (I get lazy and just "eyeball" the weight), I very rapidly get out of practice and put on weight. It turns out humans are terrible measuring tools. And the best part is this doesn't only work for me. Everyone I know who has followed me into methodically measuring food (sample size of 6 friends, and a couple has PCOS and one has hypothyroidism but is taking pills) has had their data analysed by me and the results agree with one another - CICO IS true. I should really write up the analyses one fine day.
