Keto Coffee (1 Cup)

Use plain, unsweetened coffee and check labels on creamers, powders, collagen blends, and “keto” syrups for added sugars, maltodextrin, or starches.

Reduce the caffeine dose: try half-caf, a smaller serving, or decaf, since caffeine can raise glucose for some people even without carbohydrates.

Avoid drinking keto coffee on an empty stomach; have it with a balanced meal containing protein and fiber, such as eggs with non-starchy vegetables or plain Greek yogurt with chia seeds.

Replace sweetened or flavored add-ins with cinnamon, unsweetened cocoa powder, vanilla extract, or a non-sugar sweetener that you tolerate well.

Test one change at a time and compare your glucose response for several hours; also consider sleep, stress, exercise, and timing, which can amplify caffeine-related rises.

If the rise is frequent, large, or you use glucose-lowering medication, discuss the pattern with your clinician or diabetes educator.
