It’s a disease with different causes for different people.
For some it’s a result of mental illness and disordered eating. I’ve noticed anecdotally that it’s also linked to neurodiversity - I am autistic and never feel full, even on a GLP1, it’s like I have a highly dulled sense of satiety.
There’s growing evidence that a lot of people have an unusually high drive to eat, maybe genetic, but the cause not identified fully yet.
I’ve also seen some obesity drs suggest that one day for some it’ll be found that’s it’s a manifestation of chronic illness, in a similar way to CFS.
Then there are those who are on prescription drugs that trigger obesity. A friend at 18 was put on an antidepressant, she put on 12 stone in 18 months as a result. She’s now in her 40s and cannot shift any weight.
Once someone is obese the way bodies work changes, likely for life. This has been known for some time now but is conveniently ignored because apparently it’s so much fun berating fat people
I've been on mounjaro for the last year, within a week of taking it, even before any real weight loss, i stopped having constant pain and I lost a whole layer of inflammation that I’ve had since I was a small child. I know others have experienced this as well. To me this points towards GLP1s treating something that has been ignored for decades, because it’s far easier to assume that fat people are simply lazy and stupid, when in reality that applies to very few of us.
