Days after this study was released, a meta analysis that added up the results from 48 randomised diet trials in overweight and obese people (these were branded diets such as the Atkins, Weight Watchers, Zone and Rosemary Conley) found that over six months, people on low-carb diets lost 8.6kg (19lb) more than those not on a diet, while those on low-fat diets lost 7.7kg (17lb) more. After a year, this study found no difference in weight loss. It did not look at reductions in heart disease.
