This book is targeted to individuals who wish to make an effective long-term change to their lifestyle for improved overall health and/or weight loss. Americans spend billions of dollars on diets and diet products trying to lose weight and improve their health. But why do most fail? Are they missing root causes of the problem? We assert three reasons: diets that are not sustainable, not knowing what is in food, and not knowing how food effects metabolism. The title of the book refers to the tendency of many diet advertisements to add the phrase "along with a balanced diet and exercise" to whatever diet product or service advertised. We skip fad diets and diet products, and instead provide knowledge. Our basic concept is to use knowledge and common sense rather than following fad diets. We outline practical and philosophical principles and aspirational ideals. We further explain the philosophical underpinnings of our way based on how the human body has been optimized to live in a preindustrial natural environment over millions of years. We explain why this biological predisposition dooms most diets to failure. We explain what is in the food you eat and why your body may or may not convert the food to the energy you need. In addition, we show how to avoid jumping off the weight loss bandwagon before you reach the destination. In the Lowellie Way, we offer a structured method of replacing larger Calorie quantities of lower quality food with lower Calorie quantities of higher quality food. We outline a long-term sustainable weight loss plan of exercise and eating correct food in a correct amount to stay motivated and healthy, while enjoying the process, food, and resulting happiness.
