Do we know how efficient our bodies are converting food into energy or that excess energy into stored fat?
Any time one form of energy is converted to another there is a loss of some kind, like generating electricity from an IC petrol engine, only ~30% of the energy gets converted.
Are the joules from food the amount of joules our body see's? or is it the amount of energy that is stored in that food?
our body uses enzymes - shit that puts chemists to shame.
In some of the cycling forums, I have read food calories to work calories is 15-25 percent efficiency. I am in mobile....Check Google.

thanks
didn't know what i was searching for
>"calorie energy change" "food to energy" all that kinda shit returned mom science on me
So supposedly 40% of the calories in glucose actually go into the usable calories in ATP, the other 60% is wasted as heat
Does that mean if i ate 100 kcal of glucose, my body would only really see 40kcal?
Where does the storage of said energy come into play?
Or are calories, when linked with food, already taking that into account and 100kcal is what my body would see AFTER the 60% is lost?

If I cut out 1kg of fat from my stomach and eat it, how much fat will I loose/gain in the process?

Depends on how much fat your intestine can absorb at once, wether or not you have a healthy gallbladder and a proper bilirrubin synthesis, and on your nutritional state.

Try using a proper search engine like PubMed if you're interested on human metabolism for instance, or universities

> wasted as heat
As opposed to freezing to death?
