What is Bulletproof Coffee?

Have you heard about the latest trend of adding butter to your morning coffee? Proponents are claiming that this odd combination provides lasting energy and fuels weight loss. But what’s the science behind this latest fad? Is this a healthy idea or just another hyped-up diet gimmick?.


I asked Ryanne Gallagher to help me research this topic. Lots of you have already met Ryanne on the Nutrition Diva Facebook page, but for those of you who haven’t, Ryanne is a nutrition intern at the Cleveland Clinic and she’s working with me this month as part of her training to become a Registered Dietitian this fall.

What is Bulletproof Coffee?

Nutrition Diva: So, Ryanne, what exactly do people mean by “bulletproof coffee” and where does the name come from?

Ryanne Gallagher: Bulletproof Coffee is the invention of Dave Asprey, an entrepreneur and health blogger. It fits into his Bulletproof Diet concept, which he describes as “Upgraded Paleo.” Monica, you’ve talked about the pros and cons of the Paleo Diet in a recent Nutrition Diva podcast. If any listeners missed that, they can find it in the show archives.
