Why Long-Term Weight Loss Is Not Desirable?

The obesity epidemic has been a pressing issue for the world as overweight or obesity would bring about many medical disorders including diabetes, heart disease, high blood pressure and stroke. The consequence is huge amount of health expenses would be required to cover these diseases.

Naturally, no one would like being overweight or obese and if someone makes a statement like “weight loss is always beneficial, and weight gain is always harmful”, I am quite certain that not many people would raise their hands to object.

However, a paper published in the International Journal of Obesity on September 7, 2010 by researchers from Kyungpook National University in Daegu in South Korea revealed that long-term weight loss might release into the blood industrial pollutants, which is linked to diseases such as Type-2 diabetes, coronary heart disease, hypertension, periodontal disease and rheumatoid arthritis. These hazardous compounds are normally stored in the fatty tissues, but when fat breaks down during weight loss, they get into the blood stream and can reach vital organs.

After studying concentrations of 7 such compounds in blood of 1,099 participants in the United States, they found that those who lost weight over 10 years had the highest concentrations of the compounds, known as persistent organic pollutants (POPs), compared to those who gained or maintained a steady weight.

The findings totally opposed to the overwhelming data showing attaining a healthy weight is good for preventing many diseases. When a study that goes against the common sense, it would naturally arouse doubts or even opposition from other health professionals.

Some of them feared that overweight or obese people might use such findings as an excuse to stop trying to reduce their weights through healthy diet and exercises, while others suggested people should figure out if the study seems sound and applies to the average population.

In fact, even the researchers themselves acknowledged that further studies are required to establish the link between long-term weight loss and health problems.
