BMI is not a accurate way to see if a person is 'underweight' or not. I'm a guy, 1.70m and weight 61kg. My BMI is probably pretty low, but I'm not underweight at all. Just have a rather small frame..LaFlorecita said:Dude calm down. She is underweight. That doesn't mean she's not healthy, that doesn't mean she's about to die, just that she's too light for her height. In her case, she's probably among the 1% that doesn't get health issues at a very low weight. Froome however, because he looked perfectly normal a few year ago, probably isn't.
And yes I expect a marathon runner to have a normal bmi. My dad runs marathons. A friend of mine runs marathons. They're at a normal weight.
As is the majority of the peloton. Including Froome. It's just his transformation that's so remarkable.
So yea I do know what I'm talking about.
To determine is someone is underweight ore not use body-fat percentage.
For example a guy that goes to the gym 3 times a week will have a high BMI, but that's just muscle tissue. BMI is just a ****ty way to determine if someone is underweight, fat, ore 'normal/healthy'.
It's impossible for u to determine someone wife is 'underweight' because she has a low BMI lol
