To date neither CAP nor the ASA has seen evidence to suggest that tea can function as a slimming product. In 2002, the ASA upheld a complaint against claims that a medicinal Chinese “Diet Tea” could reduce drinkers’ weight, prevent a range of serious medical conditions and re-grow hair (Acu Herbs Chinese Medicine Centre, 3 April 2002). In 2008, the ASA upheld complaints about an ad for Conjugated Linoleic Acid (CLA) and Green tea capsules that claimed “Green Tea activates fat-burning mechanisms in the body and increases energy expenditure”. The advertiser did not provide evidence to show that the food supplement could aid slimming (Pharma Nord (UK) Ltd, 16 January 2008).
