This week I've been talking about that protein or bro-tein, depending upon how you want to pronounce it. What I wanted to do this week is give you a very brief primer on why protein is useful and why people talk about it. In this and the next 4 episodes, we're going to talk about a new protein myth each day. And today, the myth we're going to talk about is you can only use 30 grams of protein per meal. But before that, and we're just going to give you a very short primer on protein. So why do we focus on protein? Listen in and find out.
