Everyone knows you shouldn't snack on chocolate just before a meal.
But if you really must, scientists have revealed that tucking into some types may be better for you than others.
Research found that women who ate dark chocolate rather than milk or white, were less likely to overeat later, reports Daily Mail.
The study, reported in journal Appetite, added: "Of course, these results do not intend to promote the consumption of chocolate for weight management, but rather show that for women that do consume chocolate, dark chocolate may be the chocolate of preference."
Over three weeks, a Liverpool John Moores University study gave volunteers similar-sized samples of 80 per cent cocoa plain, 35 per cent cocoa milk and white chocolate.
