Hi everybody this is Monica Reinagle the nutrition diva here with your quick and dirty

tips for eating well and feeling fabulous have you heard about bulletproof coffee? It's a trend where people are adding butter

to their morning coffee. Proponents claim 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 Ryan Gallagher to help me research this topic.

Now lots of you have already met Ryan on the Nutrition Diva Facebook page, but for those

of you who haven't, Ryan is a nutrition

intern at the Cleveland Clinic, and she's been working with me this month as part of

her training to become a registered dietician this fall. Welcome, Ryan.

Hi everyone, thanks for having me, Monica.

So Ryan, what exactly do people mean by Bulletproof Coffee?

And where does this name come from?

It's actually a pretty interesting story. Bulletproof coffee is the invention of

Dave Asprey, an entrepreneur in health blogger. It fits into his bulletproof diet concept,

which he describes as upgraded paleo.

You've recently talked about the pros and cons of the paleo diet in a nutrition diva

podcast. If any listeners miss that, they can find it in the show archives.

Dave Ashbury got the idea for bulletproof coffee

on a hiking trip in Tibet, where he was served traditional Yack butter tea.

Native Tibetans drink this concoction throughout the day to stay hydrated and keep their energy up in the cold upper climates.
