Coffee (made from Ground) (1 Mug (8 Fl Oz))

Drink coffee plain or use unsweetened milk alternatives; avoid sugar, syrups, sweetened creamers, and flavored powders.

Try a smaller serving, a weaker brew, or half-caffeinated/decaffeinated coffee, since caffeine can raise glucose in some people.

Have coffee with a balanced meal or snack rather than on an empty stomach—for example eggs, plain Greek yogurt, nuts, or chia seeds.

Add protein and fiber to the meal around coffee, such as an omelet with vegetables or plain yogurt with berries and nuts.

Avoid pairing coffee with pastries, sweet breakfast cereals, or sweetened coffee drinks, which can amplify the rise.

Compare your response to regular versus decaffeinated coffee on separate days while keeping the meal and timing similar.
