So what’s more important—diet or exercise? It’s a question physiologists get asked all the time. Phillips likes to say that muscles are made in the gym and fat is lost in the kitchen. But the fact is, if you’re intent on looking and feeling good, then exercise and a healthy diet together are better than either in isolation. Both Phillips and I agree: Do both. “The two together are not just additive, in terms of overall effect,” he says. “They’re synergistic.”
