Americano Coffee (1 Mug (8 Fl Oz)) and Egg Omelet (1 Large)

Drink the Americano unsweetened; avoid sugar, flavored syrups, sweetened creamers, and milk-based add-ins.

Try decaf or half-caf Americano, especially if you notice caffeine raises your readings even without added sugar.

Add non-starchy vegetables to the omelet, such as spinach, mushrooms, peppers, tomatoes, or zucchini, for more fiber and volume.

Include avocado or a small portion of nuts or seeds with the omelet to slow digestion and improve fullness.

Skip common breakfast sides that can raise glucose more quickly, such as toast, pastries, hash browns, and sweetened yogurt.

Take a 10–15 minute easy walk after eating, and compare your response on days you have coffee before versus with or after the omelet.
