Bulletproof coffee is popular among people following the keto diet as it is richer than regular coffee. According to Medical News Today, the Food and Drug Administration (FDA) has not assessed the benefits of bulletproof coffee yet, but people who drink it have said that it keeps them energetic all morning, doesn’t make them feel hungry, and improves their ability to focus. Since caffeine already gives you energy, adding butter (which has calories) can help make you feel fuller for longer than if you were drinking plain coffee. This coffee might benefit people on a low-carbohydrate or keto diet for health reasons as long as they drink it in moderation.
You probably wouldn’t think it, but butter coffee can help you lose weight as well if you’re following a keto diet (via Greatist). Make sure to choose grass-fed butter as it has more omega-3 and vitamin K than normal butter, making this latte-looking coffee more nutritious.
According to Ayurveda, consuming a spoonful of ghee (clarified butter) on an empty stomach helps “lubricate the gastrointestinal track, all tissues and remove toxins” from the body and slows down the body’s ability to absorb nutrients too quickly keeping you fuller for longer, per Aithein Healing. Since drinking butter on its own may not appeal to most, one can wonder if mixing it with coffee was inspired by this idea.
