'Precision Weight Loss': Is This The Future Of Dieting?

A diet regimen that works for one person may not work for another.

Now, new research conducted by scientists at the University of Texas at Austin shows that within five years, doctors may have diets based on an individual patients' genes.

"When people hear that genes may be playing a role in their weight loss success, they don't say, 'Oh great, I just won't exercise any more,'" said Molly Bray, a geneticist and professor of nutritional sciences at the University of Texas Austin, in a news release. "They actually say 'Oh thank you. Finally someone acknowledges that it's harder work for me than it is for others.' And then I think they're a little more forgiving of themselves, and they're more motivated to make a change."

During the study, researchers examined genetic tests, genomic research and changes involving weight fluctuations. They discovered that while some genes related to weight were identified, there's a lack of understanding in just how they actually affect weight.

In the future, researchers hope that data collections relating to how individuals gain and lose weight, as well as a better understanding of what influences the ups and downs of weight--including things like diet, physical activity and overall stress--can help form future diet plans. When combined with genomic data that involves computer algorithm, researchers believe that the development of analysis tools may not be far off. 

"I think within five years, we'll see people start to use a combination of genetic, behavioral and other sophisticated data to develop individualized weight management plans," said Bray.

The study is published in the journal Obesity.
