Some clients choose to not change caffeine intake while on a fast while others drop it cold turkey*. One of the effects caffeine has on your body is it increases metabolism, or the rate at which your cells consume energy. This is why caffeine is often used as an appetite suppressant and is a common ingredient in diet pills. But as caffeine wears off it can have the opposite effect on the body.
Stimulated by caffeine, your cells burn through much of the sugar in your bloodstream, decreasing your blood sugar level. This can, in turn, make you feel hungry. It also causes you to release sugar from the liver into the blood**. The rapid rise and fall of blood sugars becomes difficult to regulate thereby increasing the desire to eat and makes the fast more difficult. Additionally the fluctuation in blood sugar can increase mood swings, irritability & cause dizziness and/or weakness. Those with pancreatic issues, hypo/hyperglycemia will have more difficulty during the fast and should seek advice from their healthcare provider before embarking on a fast/cleanse.
Dropping coffee ‘cold turkey’ can lead to headaches and cold chills. Should you choose to remove coffee, for a fast or as a dietary goal, do so slowly. Transitioning to green tea can help eliminate headaches that might happen.
