SPORTS drinks contain so many calories that they can cancel the good effects of exercise, according to a new study.
The study, carried out by researchers at Oxford and Harvard Universities, found that many energy drinks which are marketed towards gym goers are misleading.
Researchers explored hundreds of claims used in the marketing of sports drinks. For example, it found a 380ml bottle of Lucozade energy contains 266 calories, six more than a mars bar. This would take over half an hour of brisk jogging to burn off.
They also examined the claims of many energy drinks that they could increase endurance; however the researchers found this to be of limited relevance, owing to the fact most of the testing of energy drink companies is on elite athletes.
Dr Matthew Thompson, from the Oxford Centre for Evidence Based Medicine, told the Telegraph drinking such products: could completely counteract exercising more, playing football more or going to the gym more, in terms of weight loss.
