Dr. Walk?s Philly Fit-Step Diet is a unique weight-loss, body shaping, and cardiovascular fitness plan. This program consists of a healthy low-fat, high-fiber diet, combined with an aerobic walking plan and easy-to-use strength-training exercises. This combination of diet and exercise increases the metabolic rate, which produces a double-blast of calorie burning for quick weight-loss and complete cardiovascular fitness. Dr. Stutman?s Philadelphia patients have lost weight quickly and permanently, and have become physically fit using the Philly Fit-Step Diet over the past decade.
