This adds to my point, it does not subtract to my point.
Not only is the fat digestion process inefficient, but on top the fat absorbtion process consumes more energy to make happen ( that heat )
We'd have to see where in the large 5-15% ranges various items stand.
Sugar dissolving in water... I'd be amazed if that released 15% of the energy. I'm still amazed it would be as high as 5%, so thanks for that info
EDIT: spatular set me straight with a detailed process for sugar absorbtion
- spatular 10y agoWell, fat digestion seems to be effective even comparing to hydrocarbons. I think longer hydrocarbons including sugar have to be broken into fructose and glucose during digestion. Fructose cannot be immidiately consumed by cells, so it's converted into glucose in liver. On top of that, there are about 5g of glucose total in bloodstream at any given moment, so exess have to be accumulated by liver/muscle cells that have to store it in a long-chain hydrocarbon form (glycogen). Each conversion requires some energy, so 5-15% isn't that much...
