HiPaCC take a very human and practical approach to dieting and weight loss, experience gathered from over thirty years in the art & science of weight loss. Accordingly we have put our program to the test in two trials, actively seeking subjects who have found weight loss in the past particularly difficult, if not impossible. In June 2006 HiPaCC concluded a larger ten week trial of 22 subjects aged between 20 and 59, some of whom undertook the HiPaCC diet alone, and some who followed both the HiPaCC diet and exercise program.

Over the ten week trial the sixteen subjects who followed the HiPaCC diet program alone lost an average of 13lbs in body weight, while the six candidates who followed the HiPaCC diet & exercise program lost an average of over 15lbs in body weight. This trial demonstrated that the HiPaCC diet program is sufficient for the average person to lose a full stone (14lbs) in weight over a ten week program, although one individual recorded a loss of 40lbs without missing meals.

% body fat composition was measured to show that the HiPaCC Diet targets body fat rather than triggering a loss of muscle protein or water, as many low carb diets cause water loss by depleting the body's glycogen reserves. As expected, the average % body fat decreased from 31% to 20% over the ten week trial period (the average % body fat for a woman is around 25% and for a man 14%). The best individual improvement for a man was a decrease from 24% to 14% body fat, and for a woman 32% to 22%. To show that these averages represented an improvement in body form, average hip and waistline measurements were measured, showing a marked improvement across the trial group. The best individual performances were a decrease in waistline from 37" to 33" for a man, and 41" to 34" for a woman. We thus believe that the HiPaCC diet represents a major advance for weight loss.
