well, first off metabolism is only about 40% efficient which is around the same number for a coal burning power plant, so the body is no more efficient than other methods. Second, converting anything to heat is ~100% efficient. Converting fat to heat is really really easy, i take a match and light the fat on fire. Although, this clearly cannot be even a remotely serious question since a pound of fat is only a tiny amount of energy compared to what a house normally uses in a day. Maybe if you were 100 lbs overweight and you removed all that fat and burned it you could get one free day of heating for your house, but thats about it. The thought is just completely ludicrous. I'm not sure if this is a parody thread or not, but either way it jsut doesn't make sense.

EDIT: so i did like 10 seconds of research and went to a site that said you need to burn 4,000,000 calories to lose a pound of fat, that converts to 4.65kWh. Thats what, like 30 cents of electricity?

Well your research is wrong because 3500 calories=1LB of fat FYI.

Calories in food are really kilocalories.

1 Calorie = 1000 calories

Nice. Goku, have you even seen a chemistry book?

An active person requires 3500 calories per day to stay fit, which relates to roughly 4000 watts in 24 hours (1 food calorie = 1.16 watt-hour).

5 seconds of Google FTW

Are you trying to compliment me in a weird sort of way?? 3500 calories = 1LB of fat. Most people refer to kilocalories with out realizing it, nothing wrong with speaking about it in the simplified form. Nonetheless 4,000,000 is wrong.
Ye

You can't be this stupid...

It would be 3,500,000 calories = 3500 Kilocalories = 3500 Calories == Energy content of 1lbs of fat. If anything, Browntown was slightly overestimating the energy of a pound of fat. Either way, it's still obvious that you are only going to get 4 KWh per pound, which only took me 5 seconds to find out. 4KW are not going to be worthwhile for heating a home. Portable electric heaters are 1KW.

4000kw != 3500kw!
