I'm thinking about starting a very low dose when the pills come out in Europe. That gives an extra year for more data.
For me it's purely about health (well, about 90% about healthj). I'm a marginal case weight-wise, but the overall health impact profile looks spectacular. If a pill seems likely to add a number of healthy years to my lifespan, yes please. But the more data the better.
One thing that held me back was, I'm very averse to addiction, to anything that might have withdrawal symptoms. People report being ravenous and needing to eat all the time when they quit. BUT - the data shows that after one year, people still retain about 25% of their weight loss, and at two years they're about baseline (some above baseline, some below - the "above" people may be due to sarcopenic obesity, in that you put fat back on faster than muscle, and so your metabolism is lower until the muscle comes back). This is very different from when you diet to lose weight and then stop dieting - you're not ravenous at all, you finally have satiation.
But given the weight regain stats, and the general way these work, what I think is going on is: when you lose weight, you've been training yourself for months on how to ignore or alleve your hunger pangs, so when you stop, you're well trained to it. Whereas GLP-1 agonists are just the opposite: you don't even need to think about resisting the temptation to eat, it just comes naturally; you can get pleasure from something, such as a tasty dessert, without feeling the need to eat everything on your plate; pleasure and craving get separated. So people who just suddenly cut off from GLP-1 agonists are "mentally unarmed" for the reversal. The weight-regain stats however suggest that it doesn't leave you long-term disabled in this regard; that you're just back to your old self once you readjust, whatever that old self may have been.
