Mariel Booth, a professional model and New York University student, reaches for Tofutti Cuties at a Whole Foods grocery store near her apartment in New York city. (From the book What I Eat: Around the World in 80 Diets.) The caloric value of her day's worth of food on a day in the month of October was 2400 kcals. She is 23 years of age; 5 feet, 9.5 inches tall; and 135 pounds. At a healthier weight than when modeling full-time, she feels good but laments that she's making much less money. MODEL RELEASED.
