Scientists from the University of Nottingham have discovered that drinking a cup of coffee can stimulate ‘brown fat’, the body’s own fat-fighting defenses, which could be the key to tackling obesity and diabetes.
The pioneering study, published today in the journal Scientific Reports, is one of the first to be carried out in humans to find components which could have a direct effect on ‘brown fat’ functions, an important part of the human body which plays a key role in how quickly we can burn calories as energy.
Brown adipose tissue (BAT), also known as brown fat, is one of two types of fat found in humans and other mammals. Initially only attributed to babies and hibernating mammals, it was discovered in recent years that adults can have brown fat too. Its main function is to generate body heat by burning calories (opposed to white fat, which is a result of storing excess calories).
People with a lower body mass index (BMI) therefore have a higher amount of brown fat.
Professor Michael Symonds, from the School of Medicine at the University of Nottingham who co-directed the study said “This is the first study in humans to show that something like a cup of coffee can have a direct effect on our brown fat functions. The potential implications of our results are pretty big, as obesity is a major health concern for society and we also have a growing diabetes epidemic and brown fat could potentially be part of the solution in tackling them.”
