What is the Zone Diet and who are its detractors?
Both doctors and vegatarians have taken shots at the health claims of the Zone Diet. Vegatarians argue against the Zone diet’s focus on protein, while Barry Sears has criticized the Vegatarian and Vegan diets as fueling the body in a less efficient way, because proteins are important to the body’s metabolism. Doctors, diet experts and medical experts have criticized the high protein intake of the Zone Diet, as well as what they call the “lack of essential nutrients’. Barry Sears claims that the high protein criticisms are inaccurate. Mainstream medical opinion is that hormone balance is not created through caloric intake. At the same time, medical experts on the Scientific American Frontiers show were surprised to find that the Zone Diet performed better than its competitors in the independent documentary on PBS. The Zone Diet spurred its users on to greater weight loss than other low-carb diets that were in the competition.
