Richard David Feinman sanoo suoraan, ettei pitäisi lähteä käräjöimään asiasta, joka on jo oikeudessa ratkaistu. Termodynaamiikan lainalaisuuksista seuraa, että se miten paljon kalori kerryttää painoa riippuu ruokavaliosta. Vain kemiasta mitään ymmärtämättömät ravitsemus"tieteilijät" saattavat moisesta selvästä asiasta kinata.
“A Calorie is a calorie,” uncoupling and collateral estoppel.
Lainaa:
have taught nutrition and metabolism for many years but I got into nutrition research because the laws of thermodynamics were, and still are, invoked frequently in the discussion. Whereas, like most chemist, I wouldn’t claim to be a real expert, I like the subject and I could see that nobody in nutrition knew what they were talking about. I tried to show that that, the application of thermodynamics, if done correctly, more or less predicts that different diets will have different efficiencies (from the standpoint of storage, weight gained per calorie consumed).
But you don’t really need thermodynamics to see this. Wendy Pogozelski pointed out that if you think about oxidative metabolic uncouplers that is all you need to know. “Coupling” refers to the sequence of reactions by which the energy from the oxidation of food is converted to ATP, that is, useful biologic energy. The problem in energy metabolism is that the fuel, as in many combustion engines, proceeds by oxidation. The output is a phosphorylation reaction — generation of ATP from ADP, its low energy form. It turns out that the mitochondrial membrane couples the two process (oxidative phosphorylation). Uncouplers are small molecules or proteins that disengage the oxidation of substrate (food) from ATP synthesis, allowing energy to be wasted or channeled into other mechanisms, generation of reactive oxygen species, for example.
Ketogeenisen ruokavalion metabolinen etu on todellinen, eikä se ole ei ole ristiriidassa termodynamiikan lain kanssa, vaan seurausta siitä. Case closed. Piste. Hajaantukaa, täällä ei ole mitään nähtävää!
