It is estimated that at any given time almost 116 million Americans are dieting. Unfortunately, research shows that people who diet regularly are more likely to experience weight gain. Clearly, weight loss alone is not the key to long-lasting fitness. But neither is exercise. Most people who begin an exercise program drop out after just a short time. Our ancestors were fit out of necessity; they didn"t have to work at it. And that"s why most diets and exercise programs are not successful in the long term. We just aren"t hardwired for rigid exercise routines and restrictive dieting. Fortunately, there is a simple way to achieve lasting overall fitness. In Hardwired for Fitness, John Ivy and Robert Portman explain that because the body is naturally inclined to be fit, there is no good reason for anyone to be overweight or out of shape.As readers of this book will discover, the fitness circuitry in the human body is a remarkable, integrated piece of engineering. When the circuits are functioning in harmony, they can activate the body"s metabolic machinery far more effectively and safely than any commercial product. For example, the human body has the natural ability to:o Burn fat more quickly than most hyped thermogenic supplementso Decrease food intake more effectively than the most costly appetite suppressanto Synthesize protein faster than the leading protein powderBased on more than fifty years of research and recent breakthroughs, Hardwired for Fitness shows how anyone can switch on their four main fitness circuits and, with minimal lifestyle change, achieve the level of fitness he or she has always wanted.
