Could coffee be the secret to fighting obesity?

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, that might be the key to effort obesity and diabetes.

The pioneering study, published nowadays within the journal Scientific Reports, is one amongst the primary to be dispensed in humans to see out elements that may have a right away impact 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 operate is to come up with 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: “Brown fat works in a different way to other fat in your body and produces heat by burning sugar and fat, often in response to cold. Increasing its activity improves blood sugar control as well as improving blood lipid levels and therefore the additional calories burnt facilitate with weight loss. However, until now, nobody has found an acceptable way to stimulate its activity in humans.

“This is that 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.”

The team started with a series of stem cell studies to see if caffeine would stimulate brown fat. Once that they had found the proper dose, they then moved on to humans to see if the results were similar.

The team used a thermal imaging technique, which they’d previously pioneered, to trace the body’s brown fat reserves. The non-invasive technique helps the team to find brown fat and assess its capability to supply heat.

“From our previous work, we knew that brown fat is mainly located in the neck region, so we were able to image someone straight after they had a drink to see if the brown fat got hotter,” said Professor Symonds.

“The results were positive and that we currently got to ascertain that caffeine as one of the ingredients in the coffee is acting as the stimulus or if there is another component helping with the activation of brown fat. We are currently looking at caffeine supplements to check whether or not the impact is comparable.

Once we’ve confirmed which component is liable for this, it could potentially be used as part of a weight management regime or as part of glucose regulation programme to help prevent diabetes.”
