How tall are these <150lbs people? How old? Are they men or women? Do their doctors think they show signs of possibly getting diabetes in the future? Obviously if there's a 5'10" 25 year old male with negligible risk of diabetes, they should keep their current weight or even increase it slightly by changing their body composition from majority fat to majority muscle by doing exercise. If someone's short, old, can't exercise for some reason, and might get diabetes at some point, there could be a role for a drug there.
How many? Enough to make this comment anything other than a meaningless anecdote?
I'm over 375lbs and nobody will prescribe it for me.
There's my counter-anecdote.
There are online providers that are effectively just pill mills for these drugs if you're actually interested. They're' expensive though... https://joinnextmed.com/weight_loss
