The Science

While many people enjoy their morning coffee without food, consuming it on an empty stomach can lead to increased acidity and digestive discomfort. For some individuals, this may also heighten feelings of anxiety and jitteriness due to the stimulant effects of caffeine. It may also cause a sudden spike in cortisol levels, which is the body's primary stress hormone.

If you find that coffee on an empty stomach causes you any discomfort or anxiety, consider having a small meal or snack before your cup of joe. Listening to your body is key, and it might be beneficial to experiment with your caffeine intake in relation to your eating habits to find a balance that works for you.
