Could your genes be responsible for weight gain?
And if so, does that mean you should adjust what you eat to your DNA?
Several companies argue that a gene-based diet is the answer. Here are the details.
With a quick cheek swab (and paying a few hundred dollars), you get a personalized nutritional plan based on your DNA. Follow him and you will feel great, lose weight, have more energy and gain mental clarity.
Who sells them? Say:
"The foundation of these companies is that we know there are genetic variants that affect how a person responds to a particular food," said David Mutch, a professor of nutrigenomics at the University of Guelph. But there is a catch. Science can not definitively say how two people with different variants of a gene react differently to dietary changes, Mutch says.
In addition, genetically engineered kits do not evaluate gene variants that are meaningful anyway, says Paul Franks, professor of genetic epidemiology at Lund University.
They are crammed ̵
"These kits measure the common genetic markers for protein and fat intake, but at the individual level, they have no real relevance," says Franks. A 2018 study by JAMA concluded that genes could not predict whether a low-fat or low-carbohydrate diet could help participants lose weight.
Take the money you spend on the kit and invest in fruits and vegetables instead.
