Diet Coca-Cola (Coca-Cola) (1 Serving)

Check whether the rise happens with Diet Coca-Cola alone or when it is consumed alongside a meal; the meal, snack, or timing may be the main driver.

Try a caffeine-free Diet Coca-Cola or switch to sparkling water, since caffeine can raise glucose for some people through stress-hormone effects.

Avoid drinking it on an empty stomach if you notice a repeatable rise; have it with or after a balanced meal containing protein, non-starchy vegetables, and healthy fats.

Keep the portion smaller and sip it slowly rather than drinking a large serving quickly.

Take a gentle 10–15 minute walk after drinking it, if this is safe for you, to help your muscles use circulating glucose.

Repeat the test on a different day under similar conditions and verify your meter or sensor readings; discuss consistent unexpected spikes with your clinician.
