In chapter 17, Taubes brought up a very interesting point about how our behavior is in response to our physiological needs. He gives the example of how depressed patients are totally inactive, which is their body’s effort to conserve enough energy to maintain a constant internal balance. This made me think about how people react to stress. People’s weight tends to fluctuate when they are really stressed. Some people have no appetite when they are stressed, and as a result they lose weight. Other people eat excessively as a response to stress and gain weight. I wonder what causes these different responses to the same emotion. I would think that the overeating would be a response to needing more energy to maintain a constant internal balance. As a result people have food cravings. Possibly for people who lose weight, it could be a flight-or-fight response, making food unappealing to them.
