Americano Coffee (1 Mug (8 Fl Oz))

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

Drink the Americano with or after a balanced meal rather than on an empty stomach.

Avoid sugar, flavored syrups, honey, sweetened creamers, and sweetened plant milks; choose it black or with a small amount of unsweetened milk.

Pair coffee with protein and fiber, such as eggs with avocado, plain Greek yogurt with nuts, or a small handful of almonds.

Reduce the serving size or dilute the Americano with additional hot water, then compare your glucose response over several days.

Track timing, caffeine dose, sleep, stress, and the rest of the meal to identify whether the response is specifically caffeine-related.
