Calories in -> calories out is flawed (or, rather, not useful) because metabolism is a feedback loop, not a one-way serial process. The types of foods you eat, how they're prepared, and when you eat them have complex influence for how hungry you feel and how much energy you have to exercise or resist impulses, as well as ramifications for the state of your physiology, per nutrient intake.
CICO helps explain weight management issues retrospectively, but it's inadequate with regard to planning, and for maintaining quality of life while working towards a weight management goal.

- 3vidence 2y agoTo parents point your metabolism will drastically change over those 3 months and the rate at which you lose weight will change. Additionally the distribution of your muscles and fat will also change.
- wrfrmers 2y agoI don't know the mechanics, but my understanding is that such a water fast also permanently alters your digestion and metabolism. A (logical extreme) example I was thinking of counterig with: if you eat 500,000 calories in 24 hours on the first of the year, and nothing else for the rest of it, you'll achieve a 1,350 calorie/day average, certainly enough to lose a significant amount of weight. And you will! Because your stomach will have ruptured and you'll be dead by the 2nd. Rotting is one way to burn calories. (I mention this to illustrate how focusing solely on the numbers, to the detriment of the actual lived quality of life during the weight management process, misses the forest for the trees.)
