“Sara, will I be hungry if I fast daily for 16–20 consecutive hours?”

The answer is no. Most of your fast happens when you are sleeping at night. And contrary to popular belief, the fasting phase has a suppressive effect on hunger.

Oftentimes you may think you are hungry, but in actual fact, you are just thirsty. Both hunger and thirst are controlled by the hypothalamus. That explains why you often misinterpret thirst for hunger. So when you feel hungry, drink a glass of water. You can drink as much calorie-free liquid as you want during your fasting phase.

 Remember these three things:

  • Simmer down, Pot Roast! You can eat again in 16–20 hours. And it will be awesome and worth the wait. Think of the fast as a major accomplishment. Give yourself a pat on the back for completing it and then enjoy your feast.
  • Stay busy. If you sit around thinking about food, you will want to eat. Work. Read. Go for a walk. Exercise. Have a nap. Run errands. Never sit around doing nothing when you have a craving. Distraction is key! So stay busy and your hunger won’t even be a blip on your radar.
  • Have some bloody discipline! There. I said it. Conventional dieting with its horrid food restrictions is difficult, but waiting for your next feeding window is not so hard.
