[ QUOTE ]
One of the most practiced—and accurate—ways to calculate how many calories you metabolize is to use an indirect calorimetry (spirometry). You would relax, and have your oxygen content measured over a certain period of time. However many liters of oxygen you consumed, just times that by the constant 5.047, and you have how many calories you metabolized. 5.047 can be more properly adjusted if you also have your respiratory exchange ratio (RER). You could compare the amount of oxygen consumed before and after the meal.

Now that's really cool.
Looks like you'd have to get a large sample group to account for other variables that would influence O2 combustion in the body.

Would this be done on humans? Or lab rats maybe?

I can't see a person easily taking in one certain type of fat in a large enough quantity to make an adiquate change in O2 consumption.

Now that would be an interesting lab to do.

Thanks for all the replies. Good stuff.

Fat burners of old used to rely on ingredients such as cayenne pepper. I remember they used to heat me up pretty good.
