There's a lot of dodgy weight loss claims being banded around for all these coffees. Can I just remind people of the advertising rules just in case any of them need reporting to the ASA?
Pictures of weight loss success stories are not allowed to be of obese people, no more than 2 pounds a week can be claimed. You cannot claim that just by using the product and not making any other changes, you will lose weight.
For example, if an advert were to claim you can lose 7 pounds in 7 days just by drinking special coffee and there is a picture of an obese person, this would break all kinds of rules.
