Even though chocolate is loaded with calories, it contains ingredients（材料）that may favour weight loss ___40___ than fat synthesis, scientists believe.___41___ boosting calorie intake, regular chocolate consumption was related to lower BMI in the study, ___42___ is published in Archives of Internal Medicine. The link remained even when other factors, like how ___43___ exercise individuals did, were taken into ___44___.And it appears it is how often you eat chocolate that is important, rather than how much of it you eat. The ___45___ found no link with quantity consumed.

___46___ to the researchers, there is only one chance in a hundred 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 ultimate impact on weight."This is not the first time scientists ___47___ that chocolate may be healthy for us. Other studies have claimed chocolate may be good for the heart.

Mice ___50___ for 15 days with epicatechin (present in dark chocolate) had improved exercise performance and observable changes to their muscle composition.They say clinical trials are now needed in humans to see ___51___ this is the case.

But before you reach ___52___ a chocolate bar, there are still lots of unanswered questions. And in the absence of conclusive evidence, experts advise caution.While there's no harm in allowing yourself a treat like ___53___ now and again, eating too much might be harmful because it often ___54___ a lot of sugar and fat too.And if you are looking to change your diet, you are ___55___ to benefit most from eating more fresh fruits and vegetables.
