　　It found those who ate chocolate a few times a week were, on average, slimmer than those who ate it occasionally.

　　Even though chocolate is loaded with calories,

　　it contains components that may favour weight loss rather than fat synthesis (合成), scientists believe.

　　Despite boosting calorie intake, regular chocolate consumption was related to lower BMI in the study, which is published in Archives of Internal Medicine.

　　The link remained even when other factors, like how much exercise individuals did, were taken into account. According to the researchers, there is only one chance in 100 that their findings could be explained by chance alone.

　　Lead author Dr Beatrice Golomb, from the University of California at San Diego, said, “Our findings appear to add to a body of information suggesting that the composition of calories, not just the number of them, matters for determining their impact on weight.”
