If you’re extra focused on hitting your macros, Peter Rahal has more to do with it than most other people. He’s the co-founder of RXBAR and, more recently, David Protein. 
With David, Rahal and his team have figured out how to capture attention for something as commonplace as a protein bar while using minimal advertising and sleek, simple packaging. It appears David has struck gold again with their newest product, ice cream. The $15 pints sold out in less than a half hour. 
On this episode, Liz and guest host Grace Snelling go deep with Rahal on how he built yet another protein empire and the design choices that went into it.
