Low-fat diets 'not best way to lose weight'
Adopting a low-fat diet and foregoing guilty pleasures such as crisps and fry-ups (inset) may not be the best way to slim, a study has found.
Experts who analysed data on more than 68,000 adults concluded that curbing fat intake did not lead to greater weight loss than low-carbohydrate or Mediterranean diets.
Scientists pulled together information from 53 trials comparing the ability of low-fat and other kinds of diet to shed unwanted pounds over a period of at least one year.
They found no significant difference in average levels of weight loss between reduced-fat and higher-fat diets.
Diets that cut out fat were actually slightly less effective than those based on lowering carbohydrate consumption, the researchers reported in a medical journal. Compared with not dieting at all, avoiding fat resulted in 5.4kg being shed after a year, while low carbohydrate diets added another 1.15kg of weight loss.
