Dr. Eric Berg: On Ramadan Fasting

Dr. Eric Berg discusses the relationship between fasting during Ramadan, and its immune effects.

Ramadan lasts between 29 and 30 days. During Ramadan, you’re required to not eat or drink anything from just before sunrise to just after sunset. This is a dry fast, which means you’re not drinking any water.

What you eat before and after you fast is going to make or break your success. Having junk food or refined carbohydrates before and after your fast could inhibit some of the effects you could achieve from fasting. However, low-carb, keto-friendly foods may be much more beneficial to have during your meals. Ketones are even anti-microbial.
