Brown fat: Your body's winter warrior against obesity

New Delhi (The Uttam Hindu): The very mention of fat brings a frown on people's faces, as fat is always associated with obesity, which is true to a large extent, but there are two types of fat found in the body, which are called white fat and brown fat.

Both of these fats are essential for the body, but in limited quantities. According to experts, brown fat is a form of white fat, but their functions differ significantly. White fat serves as a storage medium for energy, but when it transforms into a calorie-burning state, it is called brown fat or brown adipose tissue. Therefore, brown fat is burned when energy is needed, keeping the body energized and providing heat.

Therefore, brown fat does not contribute to obesity, but rather reduces it. It also helps increase metabolism. Brown fat is very helpful in keeping the body warm in winter. It burns itself to provide warmth. It is a protective shield during winter. It contains a high amount of mitochondria.

Now the question is why brown fat is important for the body. Brown fat increases metabolism, aids in blood sugar control, improves insulin sensitivity, keeps the body warm in cold weather, reduces the risk of obesity and type 2 diabetes, and helps burn calories. Research shows that people who are less obese have higher amounts of brown fat and are more active than those who are overweight.

Meanwhile, a lack of brown fat indicates an excess of white fat in the body. This leads to fatigue and energy deficiency, a slower metabolism, increased sensitivity to cold, weight gain, and an increased risk of insulin resistance.

Obviously, brown fat isn't obtained through diet; it needs to be activated within the body. This requires a nutritious diet and adequate exercise.
