In this video, we’re going to talk about fasting and sleep cycles.

Inside your brain, you have a circadian clock. This is a timing mechanism. The name of this clock is called the suprachiasmatic nucleus. This clock is located in the brain and is highly influenced by eating, temperature, stress, light, and darkness.

This means that when the temperature is cold, you get hungry. When you’re stressed, or there’s too much light, you won’t be able to sleep. When it’s dark, you get a spike in melatonin, and you might be more tired.

When you’re not sleeping, your appetite goes up. Eating, in general, creates stimulation of your organs, which will keep you from sleeping. Diabetics also have a risk of sleep apnea. This is because of high levels of insulin. Frequent eating and too many carbs trigger insulin.

This is why the worst time to eat is right before bed.

Frequent eating confuses your brain because you’re creating constant stimulation to your brain. But, intermittent fasting gives your organs and brain, including your circadian clock, a chance to rest and heal. This is why intermittent fasting may improve your sleep cycle. When you do fasting consistently, you actually require less sleep.
