Why so many dieting advertisements?

[JUG]

I don't fully understand how internet advertising works, but I seem to get a lot of dieting advertisements on VG chartz. I can appreciate the gaming adverts; I might feasibly consider trying out World of Warcraft one day. But I'm rather less likely to want to find out 'that one secret to getting the bikini body you've always wanted'.

I'm not sure they're targeting the right crowd here...
