Coffee - Black Coffee, 1 cup (1 serving)

Drink your black coffee with or after a balanced meal rather than on an empty stomach, especially if you notice a consistent rise with morning coffee.

Try a smaller serving, half-caf, or decaffeinated coffee; caffeine can raise glucose in some people even without added sugar.

Avoid adding sugar, syrups, sweetened creamers, or flavored milks; choose unsweetened milk or a small amount of unsweetened Greek yogurt on the side if you want food with it.

Pair coffee with protein and fiber, such as eggs with vegetables, plain Greek yogurt with berries, or a small handful of nuts.

Have water alongside your coffee and avoid drinking it quickly; slower intake may make the response easier to assess.

Test different coffee timing and preparations for several days—such as after breakfast versus before breakfast—to identify the approach that produces the smallest rise for you.
