Can you drink coffee while fasting? Drinking coffee while doing any type of fasting will not affect you in a negative way. There is this myth that drinking coffee will suppress your appetite but there is no scientific evidence that validates that claim. Drinking water is a much better appetite suppressant than coffee.

Some of the benefits to coffee drinking and fasting is the reduction of inflammation in the body. There is scientific research that suggests drinking coffee and fasting will reduce inflammation. There is also research that links drinking coffee with a decreased risk of Type 2 diabetes. And there is research that shows that drinking up to 3 cups of coffee per day shows a 19% reduced risk of death from heart disease.

One of the more popular methods of intermittent fasting is fasting for 16 hours and eating during an 8-hour window.  Intermittent fasting has become extremely popular because of the positive neurological effects to brain health. And the protection against age related diseases. There are some research studies that shows that regular coffee consumption and intermittent fasting is associated with a reduced risk of Alzheimer’s disease and Parkinson’s disease. Some studies say it can reduce the risk of mental aging decline.

If you add stuff like cream or sugar or any type of sweeteners to your coffee which adds calories that can negate the benefits of your fasting. Drinking black coffee by itself while you are fasting will not hurt you nor will it suppress your appetite. If you drink moderate amounts of coffee during that fasting state, you are perfectly fine. But as I said earlier if you really want to do something that will heighten your appetite suppressant effects while fasting your best bet is to drink water.

The Bottom Line is drinking coffee during your fasting period will help with reducing inflammation and improving brain function. But there is no major benefit from a weight loss perspective to drinking coffee while fasting. It won’t hurt nor will it help you.
