Tag: Does black coffee break a fast

According to Johns Hopkins neuroscientist Mark Mattson, our bodies evolved to survive and thrive for long periods without food. The good news for intermittent fasters is that this does not mean you have to endure your fasting window completely without fluids; you can have liquids while intermittent fasting, as long as they are carefully selected to avoid breaking your fast.

According to a 2020 study, drinking black coffee after a short fast does not significantly impact glucose or triglyceride levels. This brings into focus the popular question: what can I put in my coffee while fasting without disrupting its core benefits? The answer depends on your fasting goals, as some low-calorie additions may be suitable for weight loss but not for a 'clean' fast.
