Now available in paperback, Naturally Slim and Powerful, introduces a revolutionary diet program proven to produce up to 65 percent more weight loss in women than conventional diets. Why? The program is based on foods that naturally boost serotonin levels in a woman's brain. Serotonin is the chemical that controls emotion, intellect, and appetite. According to authors Dr. Philip Lipetz and Monika Pichler, conventional diets actually decrease serotonin levels in the female brain, thereby triggering a variety of problems for women -- depression, weight gain, food cravings, irritability, stress, and more. In other words, conventional diets actually trap women into choosing between weight loss and having the proper level of serotonin to maintain good mental and physical health.
