Definition of appestat in English:



  • The region of the hypothalamus of the brain that is believed to control a person's appetite for food.

    • ‘This is because their appestat tells them to keep eating because the food in their diet lacks nutritional value.’
    • ‘Just as a thermostat regulates the temperature in your house, the appestat regulates the appetite control.’
    • ‘The entire regulatory apparatus is sometimes called the ‘appestat’ on the analogy of a thermostat, which regulates temperature.’
    • ‘Your appestat is a control mechanism that has been fine-tuned for hundreds of generations.’
    • ‘It is also thought by some authorities that bottle-fed babies are more likely to develop defective appestats than those that are breast-fed.’
