Weight loss could be linked to a combination of 14 “slimming” genes, according to a new study.
- 14 genes have just been linked to thinness. They promote weight loss.
- The more of these variations a person has in their DNA, the more weight they lose through exercise.
- However, researchers assure that lifestyle factors and diet are still essential for weight loss.
What if the secret to a successful diet depended on genes? This is what a new study from the University of Essex suggests. British researchers have highlighted 14 genes linked to thinness and weight loss. They detailed their discovery in an article published in the journal Research Quarterly for Exercise and Sport.
Weight loss: genes that help you lose more
The scientists brought together 38 people aged 20 to 40. They were all instructed to follow their diet and normal lifestyle habits. On the other hand, 17 volunteers also joined a physical activity program. These people had to run between 20 and 30 minutes, 3 times a week.
Samples were taken to study more than 1,000 genetic mutations. Additionally, weight and BMI were noted. The team noticed that weight loss varied significantly between participants in the running group. While these volunteers lost an average of 2 kg during the experiment, some lost up to 5 kg.
When checking the genetic differences between these participants, they noticed 17 genes associated with this variation. “The PARGC1A gene, which codes for PGC-1-a, was essential for weight loss and present in the participants who lost the most weight”note the authors in their press release. Another observation: the greater the number of these markers the person had, the more easily their silhouette became slimmer.
“If we can better understand someone’s specific genetic profile, hopefully that will translate into better and more successful interventions to improve health outcomes,” adds Dr Chung who led the study.
Weight loss: genetics are not everything
According to the team’s calculations, 62% of the kilograms lost were linked to genes and 37% to exercise and lifestyle factors. Thus, a healthy lifestyle remains an important element of slimming.
As Dr. Chung explains, “Genes won’t do anything without exercise and lifestyle changes, because they are all interconnected. Without intervention, they won’t show their true potential and so it doesn’t matter what genes you have.”
He adds that exercise has many benefits beyond weight loss. It boosts, among other things, mental health and cardiovascular fitness. “I therefore advise everyone to continue training even if they don’t see the difference on the scale”concludes the expert.
