Willett's first book was excellent, so I was so excited when he came out with a book geared to those of us who have weight to lose. The advice is sound and healthy, and does not cut anything out. This truly is a lifestyle plan even more than a diet. The idea of adding in healthy choices to eventually overtake the unhealthy ones is psychologically much better than feeling totally restricted. This book is truly based on science and health studies, and by no means is it a fad diet. The body score quiz keeps you mindful of what you are eating, as well as your habits. This is the first time I have looked forward to starting a "diet", and have truly believed it is one that I could stay on and adapt as needed. The Portable Plan is a great companian, as there is a fair amount of cooking on the 21 day plan. The message of the book is so positive - every little bit of good eating and exercise helps.
I cannot say yet whether it works or not. I started the 21 day diet yesterday, and so far it is great. Willett could not have chosen a better person to work with on the book. Katzen's recipes are delicious and simple. I have looked forward to and utterly enjoyed all of the recipes. I know I am eating healthfully and nutritiously. This is the book I have been waiting for my whole life!
** Update: While it takes a lot of work to follow the 21 day diet to the letter because there is a lot of cooking involved, if you are able to do it, you will not be disappointed. The meals are DELICIOUS and very well planned. There is so much food, you will be shocked to see what happens to your body.I quickly became leaner and I have had an amazing amount of energy. Granted, each person is different, but for me, my body started to change immediately even when the scale hadn't shown much change. The actual pounds may not drop off like on more of a fad diet, but I have been so happy on this plan and I and others see and feel the results. Learn to adapt it to suit your needs and it will work for you as a long-term approach to eating. Best of luck to all!**
