Coffee

Explanation

A cup of black coffee contains only 4 calories and nearly zero protein, fats, or carbohydrates.

In a 2016 study, people who consumed between 2.5 and 5.0 mg of caffeine per kg of body weight raised their blood ketone levels between 88% and 116%. Caffeine has also been shown to boost metabolism, enhance short-term energy levels, and help with fat loss.

The key to keeping your coffee keto-friendly is to be smart about what you add to the cup. Avoid whole milk, which is high in carbohydrates. Instead, try a tablespoon of heavy cream. Instead of sugar, try keto-friendly alternatives like stevia or erythritol.
