Coffee with stevia (1 piece)

Try decaf or half-caf coffee; caffeine can raise glucose for some people even without sugar.

Check the stevia product label for added maltodextrin, dextrose, or flavored creamer ingredients; choose a single-ingredient stevia extract instead.

Have coffee with or after a balanced meal rather than on an empty stomach.

Pair coffee with a small protein-and-fat snack, such as a boiled egg, plain Greek yogurt, or a small handful of almonds.

Avoid sweetened plant milks, flavored creamers, and coffee syrups; use unsweetened milk or a small amount of plain cream if desired.

Track the timing and amount of coffee, stevia, and any add-ins for several days to identify whether caffeine dose or a specific product is driving the spike.
