Mariel Booth, a professional model and New York University student, shops for protein powder from a Whole Foods near her apartment in New York city. (Mariel Booth is featured in 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. At a healthier weight than when modeling full-time, she feels good but laments that she's making much less money. MODEL RELEASED.
