I finished the book (Kindle Version) and started today with their Program, although using a modified food plan (Dec 12, 2017). I usually eat 8 hours a day and they have the program at 12 hours. Also, they suggest 3 hours between "meals" and I am used to closer meals in the morning. I am hesitant to move away from their plan, but I also realized that the quantities were too low for me based on what they consider maintenance levels. I don't "exercise", but I have an active lifestyle (gardening, wood cutting, etc.). I have a body composition scan scheduled for February and if my modified plan isn't working, I can get closer to what they recommend.
I liked that they explained the rationale for each recommendation. And I actually loved the testimonials. I have a Ph.D. in physiology and like one women, cannot imagine 13% body fat. I also cringe at the idea of 'weight-lifting' since it sounds hard. The testimonials talk about meditation after the work-out, but I haven't yet found specific instructions for that. Perhaps I missed it. I was also disappointed that the book doesn't specifically address issues like my "weak" knees that can't believe they can really do squats and not be injured or the fact that their food plan has me (type 7) at an estimated 1200 calories to start, when I know I can lose a 1.25 pounds a week at 1800. Other people have mentioned the authors steering away from fat, but I can understand that is just a sign of the time when they developed their methods. That also indicates that if the food is clean, doesn't matter too much about some of the details.
