Tag: Fasting coffee additives

According to nutrition experts, a clean fast means zero calorie intake, so the short answer is no, you can't put just anything in your coffee when fasting. The acceptability of additives depends heavily on your fasting goals, with some popular choices causing metabolic changes that defeat the purpose of a strict fast.

According to a 2020 study, drinking black coffee after a 10-hour fast did not significantly affect blood sugar or triglyceride levels, suggesting it does not break a fast. However, the real answer to 'can coffee interrupt fasting' depends entirely on what you add to your morning brew and what your specific fasting goals are.
