As someone on semaglutide therapy, I can share that a large calorie deficit hits you in the wills to live. At some point even just eating feels like a stop at the gas station to fuel up, and it hardly matters whether it's 87 or 95 octane. Hell, rancid fry oil would even work. At some point, you stop caring whether you eat because it feels like another chore.

Eventually your metabolism syncs up again with your energy demand and you start getting interested in food, except you're way more selective about how you're (edit: ~~spending~~) acquiring those calories. I almost can't abide by junk food, fast food, or breaded fried crap anymore. But neither do I want salad or vegetables because they're "fluffy." Too much volume, not enough calories. I want about 6 or 10 forks full of food, and then that's it. And it'd best taste good, or I can't be bothered. Restaurants easily stop looking like a good deal.

Anyway that's a digest of my diary for the last 22 months. Do with the info as you will.
