Can Coffee Be the Key to Weight Loss?

Scientists at the University of Nottingham have come to a remarkable discovery: eating one cup of coffee a day can stimulate the body's defense mechanism against adipose tissue, resulting in obesity and diabetes!

A study published in Scientific Reports looked at nutrients that affect brown fats and their function, an important part of the human body that plays an important role in how we consume calories for energy.

Brown and white adipose tissue

Brown adipose tissue, also known as brown fat, is one of two types of adipose tissue found in man. The primary function of brown adipose tissue is to create body temperature from the consumption of calories, as opposed to the white fats that result from stored excess calories. Therefore, individuals with lower BMI have a higher proportion of brown fat cells.

“Brown fats function differently from other fats in the body and produce heat by melting sugar and fat, most often as a reaction to the cold. Increasing their activity improves blood glucose control, as well as blood lipid levels, while the extra calories consumed contribute to weight loss. But so far no one has found a way to stimulate their activity in humans, ”points out Dr. Michael Symonds, one of the study's authors.

This is the first study done on humans that has shown that something like a regular cup of black coffee can affect the functions of brown adipose tissue. The potential implications of this finding are enormous, since obesity is a huge health problem, and brown fats can be a part of the puzzle of solving this problem.

Coffee as a cure for obesity?

The study team first did a study on the effects of caffeine on brown fat in stem cells. When the right dose was detected, the study was extended to humans. Increased tissue temperature has been reported in the neck area, which contains the highest amounts of brown adipose tissue in humans, in individuals who have previously consumed the prescribed dose of coffee.


The results of the study on humans showed the same results: coffee caused the activation of brown fat cells. It is not known at present whether caffeine or another coffee ingredient is responsible for this effect, and once determined, it is likely that the diet supplement industry will be built on this ingredient for slimming or regulating glucose levels in patients with diabetes.
