Mackenzie Wolfson with her prescribed day's worth of food in the cafeteria at Camp Shane weight loss cam in the Catskill Mountains, New York. (From the book What I Eat: Around the World in 80 Diets.) The caloric value of her typical day's worth of food in July was 1,700 kcals. She is 15 years of age; 5 feet, 9 inches tall; and 299 pounds. Dating back to 1968, Camp Shane is the oldest weight-loss camp in the country and is a heavy investment for parents. There are about 500 male and female campers housed in small cabins on shaded hillsides overlooking athletic fields, a small lake, and the camp's most important building, the cafeteria. ?The food here is not bad. It's not what I would order in a restaurant,? says 15-year-old Mackenzie. ?You know, its been prepared low-fat, low-sodium, but when you eat it you're like, whoa, this isn't that bad. And it's really good for me? But before everyone goes, they pig out the week before. One summer I probably gained about five pounds the week before I went to camp.? MODEL RELEASED.
