Just an aside that struck me. The phrase "laws of thermodynamics" when applied to diet has always felt a bit off and I think I put my finger on why. The laws of thermodynamics is used in physics while diet is in the realm of biology or biochemistry. While of course chemistry and biology aren't in opposition to the physics, there's a reason it's useful to treat them separately. Anyway, none of this is meant as criticism or argument. Perhaps not much more than a personal insight into phrasing.
