Ozempic works off label for weight loss while you take it, but you have to keep taking it or you will gain it back. People are gaining even more weight once the side effects of Ozempic make them stop taking it.
The frist part is true for essentially all treatments (not just drugs) for chronic diseases. If someone changes their diet for a year, and then stops maintaining this diet, they’ll gain their weight back.
Is there any data for the second part? It sounds plausible to me, but many things are plausible but not actually true.
