English breakfast tea may aid weight loss by boosting metabolism, but only if it is drunk without milk, new research reveals.
A black brew is thought to raise metabolism as its larger molecules are poorly absorbed in the intestine, which may encourage the growth of weight loss-boosting bacteria, a study found.
Prevotella is associated with plant-based diets - one that is abundant in fruit, vegetables, leafy greens, seeds, nuts, beans and lentils with little or no animal products.
Previous research suggests Prevotella may aid weight loss by influencing fat storage and how people respond to hunger hormones.
This may help to enhance the growth of beneficial bacteria involved in metabolism.
