But you did a study that proved, Yes, activity can keep the pounds off. It was this really complex study. You basically got a bunch of people, including yourself, and then you overfed them 1000 calories a day. And then you just watched what happened. Who gained weight and who lost weight. So walk us through that study. And what did you learn from this study?
Dr. James Levine: Yeah, Brett, it was extraordinary. It was called the Great Overfeeding Experiment. And that is exactly what we did. But I have to tell you, this wasn’t done using a computer watch or guessing. This was done meticulously in metabolic laboratories at Mayo Clinic. It was a big, big deal. Every single food item was weighed and measured chemically. Every single movement was captured. Every calorie burned was analyzed. And even how people change their body fat was measured using precise technology down to a few 100 grams.
