Green tea increases metabolic rate
Multiple scientific studies demonstrate that green tea extracts and their active component EGCG promote thermogenesis, enhance mitochondrial metabolism, and increase energy expenditure, thereby supporting the claim that green tea increases metabolic rate.
Papers [1], [3], and [4] specifically investigate and find evidence that green tea compounds (such as EGCG and heat-transformed green tea extract) enhance mitochondrial metabolism, promote white adipose tissue browning, and increase energy expenditure or thermogenesis. None of the provided papers refute the claim.
Green tea extracts and their active components increase energy expenditure and metabolic rate in laboratory and animal studies.
