Lol - Thanks! And furthermore - it's not so much about being "right" or "wrong" about some measurement basis for food, it's about understanding what's actually happening in our bodies. That is my focus. I take it everyone else on www.myfitnesspal.com should find that info relevant and informative (if not, enough to make…

Sorry - another note. Reported calorie estimates are NOT a *representative* of biological usage. Not a true one, at least. There is an error rate that varies of up to about 20% (sources, sources, sources)! However, they are in fact BASED on biological usage (what was the purpose of estimating energy intake from food in the…

Sorry - another note. Report calorie estimates are NOT a true representative of biological usage. However, they are in fact based on biological usage (what was the purpose of estimating energy intake from food in the first place, then?). The usage of the bomb calorimeter (plus some further experimental steps) is an…

My intention was to explain concepts in the processes of caloric intake in biological systems - and not specifically how it is done experimentally to yield the caloric values you would see on nutritional labels. To restate, I meant to emphasize that differences in mass of a single food item (let's say a piece of meat) due…

Mass has nothing to do with calorie estimates, nor does water. In order to understand how calories are measured in food, you must understand how the calories are translated to energy requirements and usage by your cells how it relates to food breakdown in your body (metabolism). It would be good to have some understanding…

The calorie difference comes from the fact that when you consume food, the compounds that make up X (food in question, i.e., meat, vegetables, whatever it might be) require your body's digestive system to "do work" in order to break down the single units of X (the units need to be converted to ATP - energy for your cells)…
