Coffee (1 Mug (8 Fl Oz))

Try coffee without sugar, syrups, sweetened creamers, or sweetened plant milks; these additions are often the main driver of the rise.

Reduce the serving size, choose a less concentrated drink, or split one coffee into two smaller servings to see whether the caffeine dose is the trigger.

Test decaffeinated coffee or half-caf for several days under otherwise similar conditions; caffeine can raise glucose for some people.

Avoid drinking coffee on an empty stomach. Have it with a protein- and fiber-containing option such as eggs, plain unsweetened Greek yogurt, or a small handful of nuts.

Choose unsweetened milk or an unsweetened fortified soy milk instead of flavored or sweetened coffee add-ins, and measure the amount you use.

Use your glucose responses to compare coffee types, timing, and add-ins one variable at a time; if spikes are frequent or substantial, discuss them with a clinician.
