Kcal = 1000 calories
calorie = amount of energy required to heat 1g of H2O 1 degree Celsius
This is defined in chemistry 101.
This entire thread sort of makes me want to face palm.
- pharrington 11y agoUse chemistry to explain to me how a human body converts a walnut into energy. Hey downvoters, if Im wrong in thinking that the chemical processes involved in digestion are too complex to be coherently applied to a high level model of a human diet, then explain how Im wrong. Or am I just dumb for feeding the troll?
- et2o 11y agoI'm not sure if this is me misreading your comment, but this has been extensively worked out. We have really excellent knowledge of how metabolism works compared to a lot of other processes in biology. You learn this as the major, significant component of any introductory biochemistry class. I don't even know where to start here. It's quite a jump to label me as a troll.
- SilasX 11y agoIn the context of their post, the parent (as I read it) meant the operational, nutritional definition of a calorie, not the thermodynamic one. That is, when it's claimed on a label, does it mean "this is what you get from burning it in a lab" or "this is how much usable energy as ATP it becomes" or "this is the ignition delta between mouth and feces"? The thermodynamic definition doesn't tell us that.
- iopq 11y agohttps://en.wikipedia.org/wiki/Atwater_system https://en.wikipedia.org/wiki/Atwater_system protein is counted as 4 because it's harder to digest, even though it's more than 5 calories when burned carbs and fats are easy to digest so they're counted as-is
