Anecdotal, but I think this tracks with what you’re asking. I have never been obese, but due to family history of both connective tissue disorders and diabetes it has always been extremely important to me that I keep my weight in a normal range. It took an intense amount of mental effort on my part, religious food tracking and extensive exercise for decades.

When I started on a GLP-1 (due to a weird health situation that’s not really relevant), the amount of mental energy I needed to expend to maintain my weight was suddenly gone. I don’t feel sugar cravings like I used to, so I don’t need to stay so vigilant about my diet. I don’t spend my days monitoring my intake, planning out a rigorous fasting schedule, working out more than I’m naturally inclined to just to counteract that brownie I couldn’t stop myself from eating. It’s both a literal and emotional weight off. I am taking a very low dose but even so I honestly can’t believe the difference. I am one of the ones who was will-powering through calories in/calories out and it was miserable. Now it’s just…not.
