Is Calorie-burning Fat Just a Myth?

Have you ever heard about “calorie-burning fat”? If not, you may wonder does it really exist or just a science fiction.

In reality, adults do have small blobs of metabolism-regulating “brown fat”, which scientists believe it exist only in babies and children. Such finding was announced in a study conducted by researchers from the Joslin Diabetes Center in Boston, Massachusetts.

The paper, published on in April 9, 2009’s issue of The New England Journal of Medicine, revealed that the brown fat or so-called good fat differs from white fat that makes up most body fat in such a way that the brown fat is active in burning calories and using energy. They also showed that the brown fat subsisted in adult humans and demonstrated, for the first time, that it is metabolically active.

According to the study, brown fat may have a role in regulating body weight metabolism. Therefore, by stimulating brown fat growth to control weight and improve glucose metabolism, the researchers believe that obesity, Type-2 diabetes and other metabolic disorders could be treated. Meanwhile, higher levels of brown fat might also help protect against obesity linked with aging.

By analyzing a database of 1,972 patients who had nuclear (PET) or X-ray (CT) imaging scans during a 3-year period for a variety of reasons, the researchers discovered that significant brown fat deposits in 7.5 percent of female patients and in over 3 percent of male patients. Most of the brown fat deposits were found in the patients' necks.

In the study, the tissue of 2 patients showing brown fat concentrations in their necks were tested and it was found that the cells had the protein UCP-1, which is unique to brown fat.

The study also found that the amount of brown fat presence depends on a variety of factors like age, glucose levels and, most importantly, level of obesity. For example, younger and thinner patients who had normal blood glucose levels had more brown fat, while brown fat was more active in cold weather as it helps in burning energy to produce heat.

It has been known that obesity, Type-2 diabetes and other disorders associated with obesity or overweight could eventually lead to heart disease. Such new discovery not only helps treat people with obesity but also helps them prevent heart disease.

  4. Although many people think of heart disease as a man's problem, women can and do get heart disease. I was in the same misconception regarding the heart disease, but was made aware by a medical checkup campaign. In fact, heart disease is the number one killer of women in the United States. It is also a leading cause of disability among women.

    The most common cause of heart disease is narrowing or blockage of the coronary arteries, the blood vessels that supply blood to the heart itself. This is called coronary artery disease and happens slowly over time. It's the major reason people have heart attacks. Prevention is important: two-thirds of women who have a heart attack fail to make a full recovery.

    The older a woman gets, the more likely she is to get heart disease. But women of all ages should be concerned about heart disease. All women can take steps to prevent it by practicing healthy lifestyle habits.

    Actually, right now I am suffering from a blockage in the coronary artery and was once blocked up to 85%. I got the stent implantation which is a mesh like spring which is used to broaden the artery and hence restoring back the blood flow. You can see further information regarding stent operation from I got to know everything regarding my stent operation from this site. I was really unaware of such a blockage. I sometimes feel dizzy, restless, lazy , but thought that to be something related to mental ability, and hence never worried about it. Once I got my basic medical checkup at Elite health medical office in Los Angeles. The ECG report went to be something suspicious. So, they advised me to have further advance diagnosis to determine and assure regarding the problem in the heart. After my MRI , CT scan and other such scans it came to me as a shock that I was facing a problem of blockage. It was quite surprising to me, and as I was not aware of anything regarding this, I was really frightened. The doctors explained me every information regarding my health and its treatment, and suggested me to have stent operation. That was some dreadful days of my life, which I faced only because I was careless about my health. It was my luck that I somehow went for a basic checkup at elite health, but every woman out there may not be so lucky.
