In The Four Hour Body, a change in body composition can occur with a blend of 3 things: exercise, diet, supplements. PAGG falls into the supplements area, and can be included when one feels 100% adherence to diet or exercise may be difficult. It can be included to maximize the benefits of diet and exercise regimes, like slow carb and Occam’s Protocol. Make sure that you are consuming enough of B-complex vitamins while on PAGG(tm) and consult your physician before starting, especially if you have medical conditions.
