Black cofee (1 piece)

Have black coffee after or alongside a balanced meal rather than on an empty stomach, especially if you notice a consistent rise.

Choose a smaller serving or dilute it with hot water; less caffeine may produce a smaller glucose response.

Try half-caffeinated or decaffeinated coffee for several days to see whether caffeine is the trigger.

Avoid adding sugar, flavored syrups, sweetened creamers, or high-sugar milk alternatives.

Pair coffee with a protein- and fiber-rich option such as plain Greek yogurt, eggs, almonds, or chia pudding made without added sugar.

Take a 10–15 minute easy walk after coffee, and track your response to identify the dose and timing that work best for you.
