Giving up coffee in any shape or form isn't an ideal situation for many people. But where does caffeine stand when it comes to the keto diet [1] in particular? The low-carb, high-fat diet has a laundry list of restrictions [2] — mostly comprised of sugar, grains, and carbs — but coffee isn't one of them, thankfully. However, there is a keto-friendly way to order your next cup of joe.
Since the diet highly encourages the consumption of fats, adding one to two tablespoons of heavy cream [3] (note: this is different from half-and-half) to black coffee is the way to go. If you need to sweeten, feel free to add a sugar-free alternative, like Stevia. Bulletproof Coffee [4] is another keto-approved choice as it contains a fatty "Brain Octane" MCT oil. But you could also make a version at home by adding coconut oil and butter (recipe here [5]) to your coffee.
Another good rule of thumb is to avoid "light" and "skinny" drinks [6] because they're usually prepared with sugar and nonfat milk.
