As a general rule, when fasting, you’re only able to indulge noncaloric beverages. To fast, after all, means to abstain. This means that, for the most part, food is something that needs to be set aside in the hours that you’re fasting. However, you can enjoy several drinks during your fast, including the following:
Black coffee
Black tea
Green tea
Herbal teas, such as peppermint, chamomile, or rooibos
Homemade light broths
Sparkling water
Unsweetened coconut water
Water
Don’t underestimate the power of water. The human body consists of about 75 percent water. In fact, water is vital in the performance of bodily and cognitive functions. However, the typical American only drinks 2.5 glasses of water a day, far short of the recommended eight glasses. Staying hydrated while fasting can help ensure optimization of the fast, including allowing fat and toxins to be transported out of the body.
