Book Summary
The End of Overeating: Taking Control of the Insatiable American Appetite by David A. Kessler
Concept
The settling point theory says the body keeps an adult’s weight within a certain range with homeostatic mechanisms, but the range is not predetermined – it’s determined by the drive to eat, the capacity to be satisfied, ability to oxidize fat, motivation, availability, etc. Stimulating the reward centre leads to more pursuit of pleasure regardless of rational need for it.
Sugar, fat, and salt make us eat more sugar, fat, and salt. A variety of readily available palatable food engages the full range of our senses and stimulate appetite. While protein empties from the stomach at 4 calories a minute, sugary foods empty at 10 calories a minute, satisfying hunger for a much shorter time. And while fat empties the stomach at 2 calories a minute, the body is slow to process those signals.
Recommendations
“Food Rehab” treats a chronic problem that can be managed but not completely cured. “We remain vulnerable to the pull of old habits, although with time and the rewards that accompany success, they do lose some of their power … Eventually we can begin to think differently about food, recognizing its value to sustain us and protect us from hunger, and denying it the authority to govern our lives.”
