Scientists say that the DNA-based diet might be the future, ending obesity once and for all. As many of the people struggling to lose weight, as well as some health care providers have already known, the dieting model one-size-fits-all isn’t really working.
But there might be hope. Researchers at the University of Texas argue that the best diet might be design on each person’s genome.
The study has been published in the journal Obesity on December 22 and it will appear in the journal’s 24th volume, in January. According to the new findings, by 2020 analysis of the human genome will become more accessible and personalized diets will be created to fit a person’s DNA.
According to the researchers, besides the fact that genetics clearly play a role in obesity and body composition, studies on families and twins revealed that the genetic makeup of a person is clearly influencing their response to weight gain and loss. Some studies discovered that individuals have genetic markers which make it harder for them to lose weight while others revealed that it is easier for men to lose weight than it is for women.
During the past decade more and more studies have analyzed the connection between DNA and body weight, obesity and dieting. As a result, Molly Bray, professor of nutritional sciences and the lead author of the study believes that during the next five years people will use genetic and behavioral data, along with other determinant factors (such as their sex and age) to develop personalized plans of weight-management.
According to Bray, current diets are very effective in short-term dieting, making it possible for people to loose weigh very fast. However, the mechanism of the so-called yo-yo effect, which describes the major weight gain following weigh loss is still a mystery for scientists all over the world. The process of weight regain is still not understood either from a behavioral or from a biological point of view.
Health care practitioners and nutritionists everywhere are looking for better ways of supporting their patient’s efforts to obtain and then to keep a healthy life and a healthy weight. But despite their efforts, things seem not to work as intended.
In conclusion, a study like this one is giving high hopes to many Americans fighting obesity, especially nowadays when one in every three Americans is classified as being overweight.
