Some people experience changes in their sleep patterns when beginning to fast. We've seen with clients that it can be a roadblock, even causing people to quit the fasting method altogether. For that reason, we've come up with a solution that works for nearly everyone.

How to Get a Good Night's Rest While Fasting

Fasting can alter sleep patterns due to its effects on hormones and blood sugar levels. Here's how to manage it.

  • Step 1: Ensure you're getting electrolytes, which help regulate nerve and muscle function, hydration, and blood pH, which can impact your sleep during fasting. To find out what your needs are check out our personalised electrolyte calculator.

  • Step 2: As caffeine is a stimulant it is important to reduce your intake by at least 12 pm to not disturb your sleep.

  • Step 3: Take 250mg of L-theanine 20 minutes and 3g of glycine one hour before bed for improved sleep.

  • Step 4: If you have trouble sleeping you can move your feeding window to 6-7 pm. But be sure these calories don't come from MCT oil. C8 MCT oil can be used to extend the benefits of fasting without breaking it. But from work with clients, we have found that some people find it causes sleep issues. So be sure, if using the oil, to take it at least three hours away from bedtime.

How Hormones Affect Your Sleep

Fasting can have an effect on hormones such as cortisol, adrenalin and melatonin. These hormones have an impact on sleep and sleep quality.

This is why supplementing with L-theanine and glycine and knowing your electrolyte needs are important as they help you to stay balanced while fasting for fat loss.

How to Stabilise Blood Sugar Levels for Sleep

Low blood sugar levels can also cause sleep disturbances. Shifting your feeding window to the evening helps combat these disturbances.

For example, eating a balanced meal between six and seven, focusing on lean proteins, healthy fats, and vegetables will help keep your blood sugar steady.

This will allow you to continue to enjoy the benefits of fasting while optimising your sleep.

Actionable Takeaways

  • Use the electrolyte calculator and get your electrolyte needs met

  • Quit caffeine for the afternoon and evening

  • Supplement with L-theanine and glycine

  • Eat between six and seven

  • Don't use C8 MCT oil three hours before bedtime
