Couch potatoes may no longer be able to hide behind the excuse of their genes making them overweight.
Scientists have confirmed even people who are naturally overweight because of their DNA can slim down by exercising.
A study on nearly 20,000 people found regular jogging was the best way to ‘blunt’ the effects of genes which raise the risk of obesity.
Lacing up and going for a jog was effective for reducing people’s height-to-weight ratio (BMI), body fat percentage and the size of their hips.
Scientists at the National Taiwan University studied the impact of exercise on 18,424 Chinese people between the ages of 30 and 70.
The team measured people’s bodies, noted how much exercise they did and looked at their DNA to see if they were naturally more likely to be obese.
More than 400 genes have been linked to being overweight, by affecting people’s appetites, their metabolisms or the way their bodies store fat.
‘Regular jogging mitigated the genetic effects on body mass index, body fat percentage, and hip circumference,’ said Dr Wan-Yu Lin, study author.
