Further, these artificial sweeteners can make you hungry and also make you crave sweets!

Additionally, consuming energy drinks during your fast will interfere with the health benefits that fasting provides. One health benefit of fasting is autophagy.

Autophagy is the body’s way of cleaning out damaged cells, in order to regenerate newer, healthier cells, according to Priya Khorana, PhD, in nutrition education from Columbia University.

The basic idea behind autophagy is that in the absence of external sources of food, the body begins to eat itself (auto: self, phage: eat), destroying and recycling its own damaged cell bits and proteins, so that new and healthy versions can be built. Autophagy is believed to be essential for helping protect against diseases like cancer and dementia.

However, when you consume something during your fast, like an energy drink, autophagy cannot occur.
