>Just read the wikipedia article on calorie. It being outside of the SI, it appears to be unregulated, so there's now the small and large calorie, so what we learn in physics as definition of kcal, is actually cal in the US. And the fine distinction, just three orders of magnitude, is lost on the casual reader of, say, dietary recommendations.

Oh! Esoterica! Check out how they guess the energy for dietary recommendations. They started with an idiotic approach, and after they learned it's excrement, they stuck to the model fiddling on it. The whole branch of science is fantasy. Nothing with a real proof. Most of the experiments are guess work, to say it nice.

I need to prepare diner. CU
