Obesity in adults and children is now a worldwide health concern. Belly fat is responsible for several diseases like diabetes, heart attack etc. Do you know that Americans spend more than $30 billion a year on different fat loss programs?

There are several theories behind overweight. Innumerable fat loss tips and solutions exist starting from exercise equipments, fat loss diet, diet supplements etc.

Why a study by Western Ontario has shaken entire fat loss industry?

Until now, there is no sure shot method known for fat loss. However, in a recent study doctors identified that the extra fat around your waist is the culprit behind the bulging belly. Probably this discovery alone will lead to new therapeutic targets for fighting obesity.

Why belly fat triggers more hunger in you?

Experts at the University of Western Ontario have identified that the hormone NeuroPeptide Y (NPY) produced by the brain as well as by the abdominal fat tissue. NPY is the most potent stimulating hormone, which stimulates appetite. This hormone sends signals to the individual that they are hungry.

Importance of NPY

Neuropeptide Y (NPY) is a 36 amino acid protein. NPY is involved in regulation of sexual behavior, anxiety and stress response, peripheral vascular resistance and contractility of the heart.

Details of the study

Prime reason behind obesity is overweight people eat more. Poor metabolism, less outdoor calorie burning activities convert those extra calories into fat. Earlier it was believed that in case of overweight people brain produces NPY in excessive amount.

Dr. Yaiping Yang carried out a study on obese rat and it was found that NPY is also produced locally from abdominal fat.

What's the importance of this discovery?

This research finds out a vicious circle where brain triggers appetite stimulating hormone which force obese people to eat more and have more belly fat. Now belly fat triggers NPY which force people to eat more and creates more fat cells.
