I am doing a research on energy intake and expenditure of athletes. How accurate is this calculator for this purpose?

Jay - I don't know what it was. Probably just a precision problem with with the mouseclick ;-)
You have to hit the button right in the center.
Anyway, the advanced calculator is considered more accurate.

Me again. It was just the classic version that didn't work, but after many tries with reloading and such it suddenly worked. Cured!

The chart won't let me be female. I've tried the other one, same thing.

Chrissy - If your total energy expenditure is 4167 kcal, you need to have an intake that is below this in order to lose weight.
Let's say you want to lose 2 lbs per week. 2 lbs of body fat is about 7.000 kcal and therefore your intake should be around 3100 kcal per day.

You could try the advanced calculator for a more precise estimate of your energy expenditure:
