Attempts to lose weight more effectively by choosing food tailored to your genes may be a fruitless endeavor. So says an $8 million study into the concept.
The news:The study assigned 609 people to low-fat or low-carb diets. Analysis of whether those diets “matched” or “clashed” with a person’s supposed genetic predispositions showed no evidence that people on the “correct” diet lost more weight than others.
Dashed hopes: A smaller study by the same team in 2010 suggested DNA-tuned diets did work better than regular ones. But this larger, more powerful experiment suggests it may’ve been a false alert. “Let’s cut to the chase,” said Christopher Gardner, a coauthor of the study, to Stat. “We didn’t replicate that study; we didn’t even come close. This didn’t work.”
