'Blood Type' weight loss program fails to meet standards of best diet plans

When it comes to achieving New Year's resolutions to lose weight, U.S. News & World Report recently came out with a list of the best diet plans. Not approved by its panel of experts: The "Blood Type" weight loss program. And now a new study is confirming that when it comes to what really works, that supposedly healthy holistic approach fails to pass the test, reported Yahoo News on Jan. 17.

To conduct their research, University of Toronto experts analyzed the blood type and diet of about 1,500 healthy young adults. They then compared their results to the diet details in the book "Eat Right for 4 Your Type: Complete Blood Type Encyclopedia."

Created by naturopath Peter D’Adamo, the Blood Type diet describes precisely what different blood types should eat for weight loss and health. Just one problem, said the researchers: There's no scientific evidence.

“It was an intriguing hypothesis so we felt we should put it to the test,” said study author Ahmed El-Sohemy in a statement.

“We can now be confident in saying that the blood type diet hypothesis is false,” he added.

D’Adamo's theory was based on what he viewed as chemical reactions to different foods that varied by blood type. He contended that type O blood types, for example, did best and could achieve weight loss easiest on a high protein diet, while type B blood types should subsist on greens, low fat dairy and greens.

So which are the best diet plans?
