Researchers say it appears chocolate has an effect on the metabolic system.
In an observational study of about a thousand adults those who ate chocolate more frequently had a lower body mass index.
The effect remained even after exercise and diet were taken into account.
Researchers say-they need to do more studies-
And don't recommend over doing it on chocolate just yet.
Erika Edwards will have more on this study in tonight's Healthbeat Report on Live at 5.
