In my opinion, CICO works when you start from a high point but tapers off afterwards. Like when I weighed 235 (which is high for my 5 foot 2 inch frame) I had breakfast, lunch and I could, literally, eat two burgers and some fries and a soda for dinner and still lose weight cause I ate no snacks in between but after I got down to 200 lbs CICO had little bearing on anything I did. Now I really had to watch the quality of the food I ate in addition to the amount of calories. (i.e. simply eating less wasn't good enough). Also, it bears mentioning that alcohol was not a thing for me. I barely drink (i.e I have like the equivalent of a beer for every 2 months). So it wasn't an option to give it up because it really wasn't a part of my diet anyways. But it's not hard to see why those who give alcohol up have a positive response.
