English breakfast tea could be the key to boosting your metabolism

Lovers of a brew, we’ve got some fabulous news for you – a recent study has found that your favourite English breakfast tea could help to give your metabolism a boost.

The research, which was conducted at the University of California in Los Angeles, found that drinking breakfast tea can stimulate the production of bacteria which can help with weight loss. However, there is a notable catch: you must drink your English breakfast tea without milk if you want to reap the benefits.

The scientists working on the study looked at the impact of black and green tea extract on mice who had been fed a variety of diets, and discovered that, over four weeks, those who’d been fed either extract showed weight loss comparable to the effects of a low-fat diet.

The findings, published in the European Journal of Nutrition, also highlighted that the tea extracts caused the mice to have fewer intestinal bacteria associated with obesity, and more microbes linked to lean body mass – but only those who’d had the black tea extract demonstrated the change in metabolism as well.


‘It was known that green tea polyphenols are more effective and offer more health benefits than black tea polyphenols since green tea chemicals are absorbed into the blood and tissue,’ lead author Professor Susanne Henning explained.

‘Our new findings suggest that black tea, through a specific mechanism through the gut microbiome, may also contribute to good health and weight loss in humans. The results suggest that both green and black teas are prebiotics, substances that induce the growth of good microorganisms that contribute to a person’s well-being.’

Study author Dr Zhaoping Li agreed: ‘For black tea lovers, there may be a new reason to keep drinking it.’

Admittedly, if you prefer your tea with milk, sugar, and more often than not, a generous helping of scones or biscuits, it might not be the solution it sounds. But if you can learn to love the taste of black tea (perhaps with a slice of lemon or two), you might find that it gives your metabolism the lift that you’re hoping for…
