I have seen some yo-yoing on here to be fair, but it tends to be either people who couldn’t afford it in the first place, or those whose heads weren’t really in it to get to a healthy weight, more drop a stone, and regain and start again.
most people are not in that bracket, it’s a tiny minority who are, and most can accurately assess their own finances short and long term and make a decision before starting in terms of if it works, this is my plan. So I don’t think there will be a lot of expensive yo yoing, but a small amount. As you’d expect.
I also recognise the mind set of how can anyone afford that. I grew up with skint parents, and they’d probably say something like that. I’m lucky enough as an adult I can afford it, through earnings and then eventually pension, but also recognise before that time price will come down as more drugs enter the market.
the poster also doesn’t know the regulations, which for mounjaro, is if you qualified in the first place, you can be prescribed for life, to avoid regain. So on a healthy weight, However you cannot get it at a healthy weight as a starting point.
I won’t yo yo, and I can see reading threads, most people won’t, but a tiny majority will. However that happens on any diet, look at slimming world, sure it’s cheap, but it’s a 97 percent regain rate.
