Ever wonder why some people can eat carbs without gaining weight while you may feel like you put on pounds just by looking at pasta and bread? The key may be in your DNA. After studying more than 6,000 people around the world, Swedish scientists discovered a gene that may make the difference. The gene makes an enzyme that breaks down carbs.
People with fewer copies of this gene had more trouble breaking down starchy foods and were eight times more likely to be obese than people who had the most copies of the gene.
