Black coffee has hardly any calories and zero carbohydrates, so it shouldn’t have an effect on blood glucose. Research is still ongoing to study its actual effects. But there is a proven issue with coffee and diabetes — the fact that most people rarely drink their coffee black. And once you start adding cream or sugar, coffee can quickly go from no carbs to carb overload.

If you take milk or sugar in your coffee, keep track of how much you put in, and factor those carbs into your meal. And when it comes to those $5 cream-topped “coffee” drinks sweetened with syrups, factor the carb counts into your meal plan and you’re likely to find they’re more like dessert.

Quick tip: If you’re used to sweetening your coffee, try adding a little bit less sugar each day — your taste buds will adjust and you’ll save yourself carbs.
