Kick-start weight loss and boost beauty with an easy 4-day cleanse and a delicious 4-week antioxidant-based program from CBS’s The Early Show nutrition contributor In The O2 Diet, nutritionist Keri Glassman translates cutting-edge science into an easy-to-do program that will leave dieters energetic, healthy, and beautiful— inside and out. Glassman shows how dieters can—and should—indulge in foods like Caramelized Pear and Pecan French Toast and Flank Steak withChimichurri Sauce and actually lose weight! For once, it’s not about counting calories or restricting what one eats; it’s about eating more of the right things. The diet is based on the ORAC (Oxygen Radical Absorbance Capacity) scale, a calculus developed by the USD A that measures how well a food protects against free radicals, the culprits behind many forms of cancer, heart disease, and symptoms of aging.
