A Stanford University researchers’ report on Wednesday revealed that a genetic test might enlighten people on what diet to switch to, low fat or low carb.

Christopher Gardner, an Associate Professor of Medicine at Stanford and a Co-Author of the study said, "Knowing your genotype for low-carb or low-fat diets could help you increase your weight-loss success".

Another study signaled that 45% of white women possess a low-carb genotype while 39% are prone to a low-fat diet, implying that the test has the ability to yield fruitful results for most of the population.

These findings clarify why two people who decide to lose weight and go on the same diet and exercise plan, show different results. Where only one succeeds, the other is left irritated.

Interleukin Genetics Inc. had developed the test. A cheek swab is used in the test to get cells for DNA study. It is available in the market for a price of $149.

"It's not the end of the obesity epidemic", Dr. Gardner said. "But we need every leg-up we can get".
