The study claims 10 per cent more people are overweight or obese than previously believed, putting them at risk of suffering serious health problems such as diabetes and heart disease.
It says that although they may have a normal Body Mass Index, the calculation usually used to determine obesity, this does not distinguish between lean mass and body fat and so they may still weigh too much.
Yes, we know that the BMI does not distinguish between lean mass and body fat. That\’s actually one of the complaints we have about it. For just about every professional sportsman would be described as (at least) overweight, if not obese, because they, umm, have a lot of lean mass.
So while it may well be true that there are those who are light but still fat, we can\’t just add 10% to our estimates. We also need to adjust for those who are heavy but not fat….
