There are a few criteria for Class III Obesity
- BMI above 40
- Over 100 pounds above normal weight
- BMI above 35 with health complications from obesity.
For my height, a BMI of 40 represents a weight of 263 pounds. I've lost 12 since starting fasting at the end of January (assuredly some of that is water weight), and am currently at 317 pounds. That is about 54 pounds away from being out of the Class III category.
One of the things I don't understand -- and this may be just a case of body eumorphia (the opposite of dysmorphia) -- is why some people have class III obesity and look it, and some people are built differently. Certainly I have a background in athletics, which might just mean I'm used to liking what I see in the mirror.
Edit:
One thing I left out here is that many many people cite BMI as a "U-shaped" curve. On Peter Attia's podcast with David Allison I also heard the idea that the curve shifts to the right as we age. 30 might be a perfectly reasonable BMI for a man in his 60s.
