 It took me a while to figure out what this science is. And luckily, they provide a wonderful coach. My coach is Tim, and he is so delightful. And he's somebody who went through it himself. He lost 150 pounds on it. So he knows what he's talking about. Oh, and by the way, he kept it off. And this is over a year or so ago. So it's a tried and true thing. It's scientific knowledge.
