There are people who take weight-loss systems seriously. And then there's Juergen Heckrodt. If you haven't heard, he operates a three-star hotel in Norden, Germany, a summer resort town not far from the North Sea and the border with the Netherlands. His approach to shedding pounds is proactive: If you wish to stay at his establishment, you'll pay according to your weight. At check-in, each guest is asked to step onto a scale before being shown to his or her room. If that makes you indignant and you refuse, you won't be tossed back out onto the street. But you will hear a lecture on the benefits of dieting and exercise. "I had many guests who were really huge," Heckrodt volunteered to an interviewer. "And I told them to slim down." His rationale: It's good for business. "Healthy guests," he said, "can come back more often." Anyway, a guest is charged a half-euro ($0.61) per kilogram, or 2.2 pounds. For, say, an NFL offensive lineman who weighs in the 330-pound range, that would work out to $91.50 per night , assuming one was vacationing there. Apparently, at least a few regular patrons have taken the hotelier up on his advice. "When they came back the [following] year and had lost a lot of weight, they asked me: 'What are you gonna do for me now?'" Heckrodt said.
