Depending on how they measure obesity, this 1B number may be greatly overinflated. One very popular measurement is BMI which only considers height and mass, and does not consider other factors like fat vs. muscle mass, body water, etc.

For example, using BMI I am considered “obese” but I have a very high muscle mass and fairly low fat percentage (17%). So am I one of these billion people?

Very few people have high muscle mass and low fat percentage.

So technically you are counted as obese but very small fraction of people counted as obese are like you.

In my 30+ years, the vast, vast majority of obese people I see don’t look like they are obese due to muscle mass.

[imtringued]

Sure, why not. Since BMI is used at the population level some outliers don't make it wrong.
