It is possible. Which is what Ghoul said. See that apostrophe? Are you looking for a reason to be mad, or is it just poor reading comprehension?
It certainly is possible for a type 2 diabetic to come off insulin.
Or even, if they expended every ounce of time and bandwidth to control each morsel they put in their mouths, to control blood glucose "manually" and never go on it. After all, type two diabetics had to that prior to insulin being developed. Of course that's a huge imposition and makes it difficult to deal with the rest of life's challenges, and so with the miracle of science, they can be freed from that burden and live a reasonably normal life.
Hypogonadism can often be improved by weight loss, exercise, changes in diet, resolving sleep apnea, addressing unresolved thyroid issues, etc, all, collectively raising Testosterone levels, But not all of these things can be readily fixed, like certain causes of sleep apnea, or finding sufficient time to exersize while still making a living, but again, either in the interim or long term, science provides an immediate fix.
My point was the lingering, archaic belief that all weight issues are simply a lack of willpower, and that after just "learning how to control yourself" after using the "diet cheat" of a GLP, everyone can drop that hormone and not revert to baseline weight as 95% do.
They seem to find the idea almost offensive, that something more rooted in a biology could be at play, like GLP-1 insufficiency, which will not be "learned" out of.
What, I wonder, do they think would be the symptoms of someone not producing enough GLP-1? Excessive appetite, beyond energy needs, and the intrusive, all encompassing thoughts that accompany it perhaps? Or is that hormone, uniquely, not subject to deficiency?
That's not to say personal choices and responsibility don't come into play. They certainly do, as manifested by muscle loss from failing to eat sufficient protein or exercising.
A funny thing though, once "food noise" is silenced. In the main, the food business is seeing a shift to not only less consumption, but rising demand for healthier, more protein dense foods from GLP users.
It's as if when given the chance to make conscious choices absent the pressure of malfunctioning biology, many of these weak people, who lack willpower, are choosing wisely.
