Of Heating And Eating
After adjusting a thermostat, most of us wait a half hour before adjusting it again because we know it takes time for the heat to come up.
The Half Hour Diet honors the same delay between meal and satiety. It takes perhaps forty minutes for the brain to receive the stomach’s hormonal signals after a meal begins (actually, hormonal signals from the intestines influence the brain’s satiety center in the hypothalamus).
Once you learn to recognize satiety, you can also learn to expect it and to wait for it.
