Regular Coffee (1 Mug (8 Fl Oz))

Drink the coffee plain or replace sugar, syrups, sweetened creamers, and flavored milks with unsweetened options.

Have coffee with or after a protein- and fiber-rich meal, such as eggs with non-starchy vegetables or plain Greek yogurt with nuts, rather than on an empty stomach.

Try a smaller serving, a slower intake, or half-caffeinated coffee; caffeine can raise glucose for some people even without added sugar.

Compare regular coffee with decaffeinated coffee on separate, otherwise similar days to see whether caffeine is the trigger.

Avoid pairing coffee with pastries, sweet breakfast foods, or sweetened coffee drinks; choose nuts, cheese, or an egg if you want a snack alongside it.

Review the pattern with your clinician if spikes are frequent or substantial, especially if you use glucose-lowering medication.
