Taubes (usually my hero) makes the argument that Guyenet is ignoring populations that were poor, eating unrewarding food, and still got fat, thus “refuting” the reward theory. Guyenet disagrees and says that their food was not necessarily unrewarding.
Taubes says that in science it is always a good idea to consider all the facts, not just the ones that fit your theory. In fact, please do it before giving a talk on the subject. Then he walks away from the mike.
As the entire audience cringe from the awkwardness of the situation Guyenet answers, with superb coolness, “Thanks for the advice.”
