Obesity gene can be overruled by exercise

Teens who inherit the ‘obesity gene’ from their parents can overcome their predisposition through regular exercise, a study has revealed.

Several genes have been linked to obesity. But scientists have found that one gene in particular – named the FTO gene – is strongly linked to increased body fat. Previously, it has been believed that those who inherit this DNA cannot overcome it. Now a study of 732 teenagers who exercised regularly has indicated that through keeping active, and eating a healthy diet, it is actually possible for those who inherit the gene to shake it off.

Kids with the gene who undertook less than one hour of exercise each day were indeed likely to live up to the promise of their DNA. On the other hand, with just 60 minutes of activity, many were able to downsize their weight and achieve a normal shape.

This new evidence comes as further testimony to the fact that keeping children active is a vital part of keeping them slim and healthy. The younger generation’s obsession with TV shows and computer games means that it can be harder to encourage kids to venture outdoors. However, through sports, dancing, or even indoor activities such as playing on Nintendo Wii fitness programmes, there are ways to help them burn off more energy. Children who exercise for an hour a day are more likely to be healthy, happier, and to have greater skills including social and cognitive abilities. As a representative from the YMCA said this week (in advance of the ‘Healthy Kids Day’ that the organisation has coming up on April 10th): “Play should not seem like a chore – it is an activity that is fun and brings joy, and allows a kid to just be a kid.”

The latest study is published in the Archives of Paediatrics & Adolescent Medicine this month. Its focus is on exercise; the other essential part of losing weight, eating a healthy diet, should not be forgotten either.
