Longer fasting results in better sleep and less disease risk. The study showed that each two-hour increase in fasting time made for longer nights of sleep. This is important not only because it helps people feel better, but also because it points to a healthier sleep-wake cycle, or circadian rhythm. An imbalanced circadian rhythm increases cancer risk, along with numerous other chronic diseases. Each two-hour increase in fasting time also reduced blood sugar and systemic inflammation, hence lowering the risk of diabetes and other diseases.
Got low blood sugar or adrenal fatigue? Then a bedtime snack may be appropriate.
While the new research makes a strong case for extended nighttime fasting, long fasts may be detrimental to those with low blood sugar or adrenal fatigue.
In these cases, allowing blood sugar to drop too low through fasting can cause a series of negative hormonal consequences that result in insomnia, mood issues, fatigue, and poor brain function.
If you wake up anxious at 3 or 4 a.m., you may be a victim of low blood sugar and need to eat a little protein to fall back asleep. Eating a little bit before bed can also help prevent those all-too-early wakeup calls.
As always, please consult your doctor.
