A new study suggests that drinking a cup of coffee can reduce obesity. How is this possible? The researchers started with a series of stem cell studies to see if caffeine would stimulate brown fat. After finding the right dose, they then moved on to humans to see if the results were similar, and the researchers found out that drinking coffee can reduce weight. Drinking a cup of coffee can be helpful to reduce obesity as well as diabetes as it stimulates the body’s fat-fighting defense.

The study was published in the Scientific Reports journal.  It has found the components which could have a direct effect on ‘Brown Fat’ present in our body. It is an essential part of a human body which plays a key role in how quickly one can burn calories.  Caffeine may boost weight loss or prevent from gaining weight. Caffeine may reduce feelings of hunger and your desire to eat a brief time. Caffeine increase energy use even when you are at rest. It activates thermogenesis- one way your body generates heat and energy from digesting food.

BAT (Brown adipose tissue) also known as brown fat, is one of two types of fat found in humans and some of the mammals. The primary function of BAT is to generate body heat by burning calories as opposed to white fat, which is a result of storing excess calories. People with a lower body mass index (BMI) have a higher amount of brown fat. BMI is a person’s weight in Kilograms divided by the square of height in meters. A high BMI can be an indicator of high body fatness.BMI can be used to screen weight categories that may lead to health problems, but it is not diagnostic of the body fatness or health of an individual.

How does Brown Fat work in the body? 

Brown fat is known as (Brown adipose tissue) works in a different way than other fats in the body. It produces heat by burning sugar and fat often in response to cold. Study’s co-director Michael Symonds, Professor at the University of Nottingham said- the activity of brown fat will increase its activity, improves blood sugar control as well as improves liquid levels and the extra calories burnt will help in weight loss. He further says that this study is the first study on humans to show them that something like a cup of coffee can have a direct effect on brown fat functions. Obesity is the major health concern for society, and nowadays, diabetes is a growing issue for all, so brown fat could potentially be part of the solution in tackling them.

The researchers first started with the stem cell study to see if caffeine can stimulate brown fat. After finding the right dose, they then moved on humans to see if results were similar. They used the thermal imaging technique to trace the body’s brown fat reserves. The brown fat is located in the neck region, so the researchers image someone after they had a cup of coffee to see if brown fat got hotter. The results were positive, and now the researchers have to ascertain that- is caffeine one of the ingredients in the coffee which is acting as the stimulus, or there is another component which helps in the activation of brown fat. Once it is confirmed, then it can be used as a part of a weight management regime or as a part of glucose regulation program which helps to prevent diabetes.
