Heavy Cream (1 Tbsp) and Coffee (1 Mug (8 Fl Oz))

Try decaffeinated coffee or half-caffeinated coffee; caffeine can raise glucose in some people even when the drink contains little carbohydrate.

Use a smaller serving of coffee and heavy cream, and avoid drinking it on an empty stomach.

Choose plain heavy cream with no added sugar, flavored syrups, sweetened creamers, or carbohydrate-based thickeners.

Have the coffee with a balanced meal or snack containing protein and fiber, such as eggs with avocado or plain Greek yogurt with chia seeds.

Test different timing: many people see a smaller response when coffee is consumed after breakfast rather than first thing in the morning.

If the rise is frequent or substantial despite these changes, review your readings and medications with a clinician or diabetes educator.
