Is is not just another myth about weight loss! It is true that drinking tea in certain amounts supports weight loss [1]. The plant substances "catechins" which are contained in tea leaves are responsible for this [1]. By inhibiting certain enzymes the fat metabolism is stimulated and this leads to a significant body weight reduction which can be maintained [1]. So this means it is not simply a question of temporary "water loss". Catechins can not only be found in green tea but also in white tea and in fruits such as apples and pears [2]. 

The consumption of green tea has also further beneficial effects [3]. Catechins that are contained in the leaves of camellia sinensis [3] show antiviral effects and prevent numerous viruses [3]. 

And looking at the media we all long for some antiviral effect right now.
