Can Coffee Fight Obesity?

Many people have always thought of coffee as a good way to lose weight because of its ability to increase metabolism. A breakthrough scientific discovery now lends credibility to this claim. The study reveals that coffee has the potential to fight obesity.

Researchers at the University of Nottingham School of Medicine collaborated with the Wolfson Centre for Stem Cells, Tissue Engineering, and Modeling to study the effects of caffeine on brown adipose tissue or brown fat.

The scholastic endeavor utilized cell models and enlisted the assistance of human volunteers. The goal is to determine the effects of coffee on the activation of brown fat.

There are two types of fat in the human body: white and brown. White or yellow fat is often associated with obesity. This type of fat is nothing more than excess energy that the body stores under the skin and in the spaces between organs in the abdomen.

Brown fat, on the other hand, plays a role in the generation of body heat. To do this, it must be able to burn calories by mobilizing the stored fat in the body as well as any excess sugar or glucose still circulating in the system.

Brown fat is what allows hibernating animals to maintain life without food for prolonged periods of time. It is also a type of fat that is present in babies, giving them warmth.

The activation of brown adipose tissue leads to an increase in the activity of a mitochondrial uncoupling protein 1 or UCP1. This protein is specific to brown adipose tissue.

The mitochondria is also known as the powerhouse of cells. It produces energy for the cell’s metabolic processes. An increase in the activity of UCP1 means greater energy production.

The study revealed that cells exposed to caffeine contained more mitochondria; hence, more UCP1. Not only is there an increase in the number of mitochondria, these cell organelles are also more densely packed.

Caffeine-exposed cells also show increased mitochondrial division. Other results included increased oxidative phosphorylation, increased glycolysis, and better cellular respiration.

All of these indicate that the caffeine-exposed cells are more metabolically-active. What this also means is that the cells generate more heat in the process.

The amount of brown fat in the human body diminishes with age. At the same time, there is an increase in white fat, also increasing the body mass index. In other words, the person gains weight as he ages.

Caffeine in coffee can help slow down the loss of brown fat in the human body. This can help improve carbohydrate and lipid homeostasis. It improves blood lipid profiles while also facilitating weight loss through the more efficient burning of extra calories.

Obesity is a very important risk factor in many health conditions, including heart disease, liver problems, and diabetes. The study provides a more credible scientific evidence that supports the use of coffee in fighting obesity and preventing many of the diseases attributed to it. Enjoying a cup of sugar-free, black coffee every day should help provide a simple approach to losing weight.
