This just in: science still good for something

As long as it’s not climate science.

Maybe there was something for the “eat-right-for-your-type” diets (based on blood type) all along: Gene Test Helps Predict Weight Loss Success.

In the long-running debate over diets—low-fat or low-carb—Stanford University researchers reported Wednesday that a genetic test can help people choose which one works best for them.

In a study involving 133 overweight women, those with a genetic predisposition to benefit from a low-carbohydrate diet lost 2 1/2 times as much weight as those on the same diet without the predisposition. Similarly, women with a genetic makeup that favored a low-fat diet lost substantially more weight than women who curbed fat calories without low-fat genes. The women were followed for a year.

“Knowing your genotype for low-carb or low-fat diets could help you increase your weight-loss success,” said Christopher Gardner, an associate professor of medicine at Stanford and a co-author of the study.

Data from a separate study indicate that 45% of white women have a low-carb genotype while 39% are predisposed to a low-fat diet, suggesting the test has the potential to yield a useful result for much of the population. The test is based on variations in three genes known to regulate how the body metabolizes fat and carbohydrates.

An unlucky few (around 15%) have both genotypes and need a low-carb, low-fat diet in order to lose weight.

Hmm.  Maybe not knowing is better?
