Life in the Fasting Lane: The Essential Guide to Making Intermittent Fasting Simple, Sustainable, and Enjoyable

by Jason Fung

Fasting allows my body to focus its efforts on using energy instead of storing energy.

There are three distinct ghrelin peaks, corresponding to lunch, dinner, and the next day’s breakfast, suggesting that hunger can be a learned response. We are used to eating three meals per day, so we begin to get hungry just because it is “time to eat.” But if you don’t eat at those times, ghrelin does not continually increase. After the initial wave of hunger, it recedes, and it spontaneously decreases after approximately two hours without food. So, studies suggest that if you ignore your hunger, it will disappear.

Eat only at the table. No eating at your desk. No eating in the car. No eating on the couch. No eating in bed. No eating during class. No eating at the movies or at a sporting event.

begin eating only dinner two days per week but not on consecutive days.

Remember: snacking is not your friend.
