No, I didn't; that was another poster. However, if you think that is claiming that thermodynamics is wrong, you're misreading it. Instead, it's claiming that the usual argument people make, when they're referencing thermodynamics, is non-scientific. (The real objection here is that chickens are not spherical. Or, less flippantly: that human bodies do not typically operate at a set efficiency with regard to thermodynamically available energy in food. The efficiency of extraction varies widely. In some cases the specific reasons are well known, and in some they are not, but assuming a set efficiency for turning food into energy (and fat) is like the physics joke "first, let's assume a spherical chicken...".)
