Why Extreme Wellness Is So Popular
Marathons, fasting, and silent retreats—the psychology behind hardcore health

Emily Fonnesbeck says her issues with diet and exercise started after her first son was born. “I was a new mom and feeling pressure to recover from the pregnancy body, and I started eating less and exercising more,” she says. “I’m very much a perfectionist, so if I’m going to do something, I’m going to do it one hundred percent.”

Today Fonnesbeck works with people who have eating and body-image disorders like the one she had. “A common theme [among clients] is that if you’re not obsessive, then you’re lazy…
