Of course if you eat less and less, at some moment you stop gaining weight. The question is what else also happens to you.

Before physiological harm, such as losing your muscles and ultimately your heart muscles, there will be psychological harm, when your hunger prevents you from thinking clearly, so you may become e.g. unable to hold your job.

I am saying this because sometimes "just eat less" is a technically correct answer to losing weight, and yet...

(And the pill breaks the link between the amount of food and how the person feels about it.)

Oh I 100% agree. I think people may be making a mistake taking an appetite suppressant and watching pounds drop thinking it means they're healthy.

The question rarely asked in modern medicine is why a symptom is present. Doctors and patients almost entirely focus on how to get rid of the symptom, in this case dropping lbs without first understanding why the weight is there.

I equate GLP-1s to simply eating less because my understanding of the mechanism is that is all it does, make a person uninterested, and even in some cases unable, to eat more.
