It's interesting that overall spending doesn't decrease that much in the end, although shifting from snacks to fruit is the kind of change health advocates have always wanted?
Don’t get me wrong, there are some people using these drugs to get out of a pit of inertia with weight and sedentary lifestyles. But it’s small. GLP-1 drugs will have most users hooked for life because they don’t have the discipline and motivation to maintain the weight loss without it. Cha-Ching!
That argument has been tried for years and yet it fails nearly 100% of the time. Should we be trying something different than claiming it's a moral issue? Or is that too scientific?
Besides, the logical consequence of the portion of my comment you highlighted is that the majority of GLP-1 patients will need to be on these drugs forever to maintain these benefits long-term. We have precisely one trial of 5+ years of patients taking liraglutide, and ~2 years for semaglutide. Some side effects and long-term consequences could be entirely unknown.
Anyway, it's fairly obvious that discipline is not a solution to weight loss, because weight gains a) happened in lab and pet animals on the same timescales they happened to humans and b) are reversed by moving to higher altitudes.
So to be productive, you should be telling people to move to Colorado.
