Are you fat?

Isn't bmi inaccurate a lot of the time?
It's a just a rough guide I think.
Doesn't let you know if someone has excess body fat.

Very rough guide, mines 27.4, over the last 6 months I've put on weight and look skinnier due to regular cycling (increase in leg and bum muscle).

There's just too many variables from person to person, I'm 6'3 and just under 16 stone which weight wise alone I'm perfectly happy with, I just need to reduce my middle age spread and retain/put that weight back on as muscle and I'm happy.

I think you need to look as muscle to fat ratio AND height vs weight to get a more sensible picture.

To look at just height vs weight (BMI) doesn't make a great deal of sense to me.

It can be inaccurate on a case by case basis so it really shouldn't be used as the sole factor in determining whether someone is healthy or not but as a large scale statistical tool for a moderately active population it works ok. I.e. it's not designed for outliers who are very fit and have a lot of muscle mass but given that outside of the internet most of the population aren't bodybuilders or professional sportspeople it's not a bad starting point. I know there are some people here for whom BMI is irrelevant because they are bodybuilders or otherwise very fit but it's amazing how many people choose to discount it as a tool because it's not suitable for a very specific group they probably don't belong to.

Apparently this chap is overweight, his BMI is almost identical to mine and I can assure you I don't look nearly as fit.

So you might be unhealthy given your build and lifestyle while he, as a professional sportsman, is not unhealthy*. It's contextual and requires some interpretation, solely looking at BMI and nothing else won't necessarily give you a sensible answer but nor necessarily will dismissing BMI out of hand just because it doesn't fit with some sportspeople.

*Or at least no less healthy than most professional sportspeople when you consider that they're often putting their body under enormous strain of various types.
