Cold coffee without sugar (1 piece)

Choose plain cold brew or iced coffee with water and ice; avoid flavored syrups, sweetened creamers, condensed milk, and toppings.

Use an unsweetened milk option such as unsweetened almond milk or unsweetened soy milk, and check the label for added sugars.

Have the coffee alongside a small protein- and fat-containing snack, such as a boiled egg, plain Greek yogurt, or a small handful of almonds, rather than on an empty stomach.

Consider a half-caffeinated or decaffeinated version if you notice caffeine itself raises your glucose.

Drink it after a balanced meal instead of first thing in the morning or after a long fast.

Take a 10–15 minute easy walk after drinking it to help blunt the rise.
