Personally I lost a ton of weight doing full-on keto (I specify, because some people just kinda cut out carbs) and then kept it off for over 2 years. But I put the weight back on after that, albeit slowly (over the course of maybe 7 years).
I've also done Mounjaro, and I can keep it off a while after I go off it, but not that long.
YES, you have to change your habits, maybe lifestyle, maybe deal with other issues in order to keep it off. But I think, not only is that difficult, it's not a "you did it and you're done" deal. It's easy to slip backwards, and I won't make any claims about you personally, but for anyone who's kept it off for less than a year, I think the good money would be on it coming back within another year. I doubt someone is "out of the woods" even two years on.
I don't know what my secret is, I lost 100lb and have kept it off for a good 5 years now. But it is a bit of an uphill battle. If I wanted to, I could easily just give in to temptation and slip right back but it hasn't happened yet.
I've had pretty good hb1ac's when my blood sugar's were all over the place and in no way healthy.
I've known many, many, people to lose weight via extreme diets such as keto. Such diets are unsustainable for almost everyone. It will work for a year or two, but inevitably, they will falter. Often it only takes a very small amount of stress - maybe a hard project at work.
I have never met anyone who uses something like keto successfully. It has always failed, with everyone I've talked to. That doesn't your diet is as extreme as keto. But, it does mean you're not out of the woods, and your perspective on this isn't exactly trustworthy.
In order for me to gain all that weight back, I would have to eat a ton of calories per day and completely stop moving/exercise.
It’s been nearly a year since I started losing all that weight and I haven’t slide back on my diet. It does take discipline
Yes, this is what usually happens. You've spent far, far more time with those calories than without.
> It’s been nearly a year
Okay, that's not a very long time is my point. It's much too early to think it's over.
I'm not saying that it's not possible to get off GLP-1s and maintain a good lifestyle. I'm saying that I don't think it's a moral failing or a lack of... sigh... "discipline" if people need to be on these drugs for life. Frankly, I think it's very rich that a baby skinny person is lecturing us on discipline. You've been doing this for less than a year. Discipline means sticking to habits for a long period of time, even when times are tough. I would not classify less than a year as that.
