From WHO:

Neat list of OECD countries (with a handful of non-oecd countries tacked on to the bottom too):

Statistically speaking, assuming we all come from OECD countries, 50% of ot.com members are overweight and need to go loose some weight!
I can't seem to see an option to do a POLL on this, but if you want, post whether u are overweight, underweight or neither. BMI calculator here that also does body fat. Remember, u can be fat and not look fat. I know someone at work, he's overweight he goes to weight watchers. Yet he looks like he's not overweight at all.
Mine BMI: 22.8, Body fat percent: 19.8%.
