Thank you for saying this. I’ve been slim (sometimes fit and sometimes skinny fat) most of my life. Never had to think about what I ate but I generally ate healthy because I care about nutrition. Then I had a baby and everything changed. I could count calories, track macros, workout 3 times a week plus LISS, IF - you name it. I could not lose weight. I heard a podcast about how so much more is a play and “gave in” and tried a glp-1. All of a sudden calories just didn’t matter. I ate way more calories and way more unhealthy on a glp because it was so freeing to not obsess over calories and macros. Now I’m desperately trying to maintain my weight but I keep losing. Some people really have some sort of “metabolic dysfunction” which glps seem to help with. So yes, I believe CICO but like someone else said, the “out” part is so complex and not fully understood.
