High-fat, high-carb meals more harmful to obese
December 28, 2007 02:31 PM - Reuters

By Anne Harding NEW YORK (Reuters Health) - Eating a high-fat, high-carb fast food meal produces damaging cellular changes that are greater and longer-lasting in obese people than in normal-weight people, a new study shows. Dr. Paresh Dandona and colleagues from Kaleida Health in Buffalo, New York looked at inflammation and oxidative stress, which occurs when levels of normal byproducts of metabolism known as free radicals exceed the body's ability to neutralize them. In previous research they found that obese individuals have higher levels of oxidative stress and inflammation than normal-weight individuals. They also demonstrated that eating a high-fat, high-carb meal increased oxidative stress and inflammation in normal-weight people. !ADVERTISEMENT! To test whether these increases might be greater in obese people, Dandona and his team had 10 normal-weight and 8 obese people eat a 1,800-calorie meal consisting of a large hamburger, a large serving of fries, a large cola, and a slice of apple pie. Both groups showed increases in oxidative stress two hours after eating the meal. By three hours, oxidative stress had returned to baseline levels in the normal-weight individuals, but it continued to climb in the obese individuals. The same pattern was seen for inflammation.
