Has anyone hit a goal weight in the 19-25 BMI range after large (75lb+) weight loss?

Though I've never had bariatric surgery, I've followed the literature on it, mostly because it is a wonderful source for studies of populations that lose large amounts of weight and keep it off for a period of years. For example, one important result is that losing weight does seem to have large health benefits that people always suspected it would. We all knew that being normal-weight all our lives is healthier, but it didn't necessarily follow that losing weight to get there would give the same results. Happily, it turns out that losing weight is good for you!

However, one disappointing result of these studies is that maximum weight loss seems to be limited for bariatric surgery patients. For example, see Weight Loss Prediction after Metabolic and Bariatric Surgery. The easiest equation to use there is Minimum BMI = Initial-BMI * 0.43 + 11. It also links a calculator that can be used to get predictions.

With GLP1s, I notice many more people writing about losing weight than are talking about maintenance. There are different explanations for why that might be. But it does make me wonder if Maximum Expected Weight Loss with glp1s is likely similar to that Initial-BMI * 0.43 + 11 equation for different starting BMIs (calulcated in the following table). If this is true, I would expect to see people getting somewhat close to their predicted BMI and then plateauing, even on large doses of GLP1 drugs.

Starting BMI	Predicted minimum BMI
50	32.5
45	30.5
40	28
35	26

I went from a BMI of 46 to 21/22 after bariatric surgery (-156 lbs). Drifted up to BMI 24ish after ~5 years and used tirz to get down to my current 18.5/19. Not sure if I could have lost that much on tirz alone.

I was able to hit a high 26 BMI from a starting BMI of 54 or 444.8lbs > 209.8lbs. I think I'd be 200 or so with skin removal on my stomach. I'm super motivated and have been almost the entire 700 days on, but at the same time I feel a bit lucky, because my wife and mom weren't able to continue losing down to their goal weights and have actually rebounded a bit from their low weights - about 20lbs each, despite still taking their shots.

With current medications and weight loss surgeries, people generally lose more from surgery. I suspect as medications continue to improve, there will be less need for surgeries.
