What percentage of males in the US with a BMI over 30 (obese) have a body fat percentage less than 25? My guess is less than 3%, but I don't have data to back it up. When studying populations you can ignore these outliers. It's well known that BMI works well for populations but can fail when looking at individual health.

Checking in - MBI over 30. Body Fat Percentage less than 10. It's not rare in my circles

  And your circles account for how much of the population would you guess?

  Really, 10% body fat with 30+ BMI? Without steroids, that sounds completely bonkers to me.. Can you link me a picture of a natural body that looks like yours, i'm pretty intrigued.

  The point is that individuals with high BMI and low body fat are rare in the general population, and can be ignored as statistical noise in most broad scientific studies. Your circles would only be relevant for studies specifically targeting body builders.

    They're not though, what? I want to see you back up this claim with evidence before passing it off as fact. Edit: It is fairly easy to be < 25% body fat with normal musculature that accompanies normal weight lifting and cardio routines 4 times a week. That will get you to a BMI +30 at 5"10 +

    What's the concentration of high-BMI-with-low-body fat in the general population ? Armed with that, I'll choose a p value myself, as to whether it's rare. Anecdotally, I agree, but I can't be sure that I am in contact with a represeentative sample.

Care to back it up I dispute that this is in fact rare. Edit:I counter with anyone who lifts and play sports and is 5" 10'+ will hit < 25% body fat and a bmi +30. You only need to be 225 pounds and at 6" 1' to be bmi +30 at 5" 10' that's only 210. I saw that fairly regularly (or at least I did precovid) at the gym.

  > I saw that fairly regularly (or at least I did precovid) at the gym. Yeah, I saw (pre-covid) it all the time at the gym, at amateur sports leagues, and at health food stores. It's also worth noting that my zipcode also has a significantly lower obesity rate than the national average. If I were to go to an Alabama Walmart the fit & muscular people people would be much more uncommon. https://www.cdc.gov/obesity/data/prevalence-maps.html https://www.cdc.gov/obesity/data/prevalence-maps.html
