This is the critical one that leads people to correctly argue CICO is largely useless for attempting to lose weight: the "CO" part of that is highly variable and is not merely a matter of being active. The body has all sorts of mechanisms that it can adjust to achieve the amount of storage vs burning that it wants to do, regardless of the amount of food consumed or the activity level.
- phil21 2y agoThe metabolism slowing down thing is greatly over exaggerated. Everything I’ve read that is evidence based puts it at a nominal difference. Put simply: starvation mode is a myth for everything but outliers that are uninteresting to discuss.
- paulpauper 2y agoyes, this. the body decides to become super-duper efficient like a Prius. this is shown by studies in which acts like walking burn less energy . There is a lower threshold in which weight loss must occur, but this can be way lower than predicted by calculators or naive CICO estimates.
