After I became concerned with getting a MI (myocardial infarction) in my sleep due to a heart rate 150 BPM fairly frequently, I started a diet called the Belly Fat Cure. After losing 8-10 pound in two weeks, I was hooked and fascinated. I came across Gary's book GCBC and put a lot of the research to work in my life. All my health problems went away, I went back to school, got my BSN and am working on my MSN (maybe another degree after I finish my MSNEd next April.
Anyway, I would like to write a more thoughtful description of my experience since it has changed my life and will continue to change my life in profound ways. There have been many things learned along the way and more to come. I am glad you are taking this paradigm to another level and hope you touch many untold people suffering from this seemingly intractable milieu of excess weight.

This is twofold. Initially, getting over my cravings was the biggest challenge I experienced during the integration or action phase of this lifestyle change. The second and more difficult challenge is ongoing due to social pressure and food availability. It has been learning about the healthiest types of foods that fit within a paleo/WAPF/Carb restricted whole foods lifestyle.
Ignore the naysayers, don't worry about how your body responds initially since it is going to be shocked on so many levels, i.e., gastrointestinal, hormonal, and type of macronutrient energy metabolism. The biggest thing one can do is learn to avoid sugar and how to identify foods that are not readily identifiable as sugar but turn into sugar after eaten.
