They don't exactly lie. This is the tricky thing with candy: it's damn hard to eat just one. Everyone (except possilby diabetics, I don't know) would be fine with eating a milky way every 2-3 days, but that's not how the brain works on sugar. I can and do rarely eat 300g of chocolate inside an hour. I'm pretty sure that's a little bit dangerous, but the only way to avoid it is to not buy the chocolate in the first place. Once I've given myself permission to start eating it's all gone real quick.
