No need for gastric bypass surgery, just eat as if you did. This is an easy read for those eager to get started on their weight loss journey. The author gives plenty of information to help you make your own decisions. For those with a significant amount of weight to lose, it is much easier to jump start into quick weight loss and modified behavior strategies, including less food consumption. It is not about counting calories in/calories out. It is about changing our relationship with eating and monitoring our hungerstat or apetstat. It really does not take large quantities of food to fuel the human body. Our cultural programming tells us otherwise. We can learn to tune into our natural hunger and satiety signals. Most diet books will maybe help you lose weight over a period of time but do not help you reset your "diet" thinking over the long term. Most of us want to lose weight quickly and move on with our lives in some common sense maintenance program. The frustration of slow weight loss usually sabotages results. This method kickstarts results and motivates towards goals of optimal wellness and reframing attitudes on food, diet and eating for long-term maintenance. For the size of the book there is a massive amount of help and common sense. This plan can work like magic but there is no magic "diet" until we re-educate our thinking about how our bodies handle food. No one has a lot of time to get through a 350-page book of how-to's and recipes. Black coffee and water fasting in the mornings and eating very lightly at lunch and dinner. The stomach and appetite amazingly adjust. Do it for yourself and don't worry what anyone else tells you about how you're eating or not eating. Anyone with an eating disorder should not withhold food, but eating disorders are mental conditions, not physical as are most health conditions that can be helped with maintaining a healthy weight. Check with your doc if you are on medication that might need adjusting. Live long and enjoy life without the stresses of extra weight and frustrating burden of constant dieting. This has worked for me and I easily maintain. If my clothes feel tight, I pay closer attention to amounts. Yes, there are many wonderful celebration occasions and daily food triggers around us. It is up to me to choose how eating makes me feel. Our bodies are all unique. Money well spent on this book. Good luck on your journey!
