Long-term weight loss may be risky to health

Long–term weight loss may be harmful to health as it can be linked to illnesses like rheumatoid arthritis, hypertension and diabetes, researchers said on Tuesday.

Blood industrial pollutants compounds can be normally originated in fatty tissues, but during weight loss, when fat breaks down, it can go to the blood stream, according to lead researcher Duk-Hee Lee who conducted the study at the Kyungpook National University in Daegu in South Korea.

Moreover, she wrote in an e-mail that we are living with a strong belief that losing weight is always advantageous, and that weight gain is always harmful to our health. She also added that we think that increased levels of pollutants in blood because ofweight loss can influence our health in different kind of ways.

In addition, Lee and her team of international colleagues examined 1,099 contributors in the United States and focus on the seven such compounds found in their blood, according to what they said in an article available in the International Journal of Obesity.

Likewise, the researchers said in a statement that once the pollutants are discharged into the bloodstream, these can be able to reach vital organs.

Also, those people who lost most of their weight for more than ten years had the top concentrations of the compounds, dubbed as persistent organic pollutants (POPs), in comparison to those who maintained a stable weight.

Lee said that there is materializing proof that POPs are not safe. POPs are associated to periodontal disease, rheumatoid arthritis, coronary heart disease, hypertension and type 2 diabetes.

Several factors were seen including age, gender and race to clarify the distinction on concentrations of these pollutants, but history of weight stayed a statistically essential feature.

Furthermore, Lee said that more studies were required to ascertain if such hazard overshadowed the benefits to be attained from weight loss.

Is Losing Weight Toxic? New Study Says Fat Releases Industrial Chemicals

Now for the completely contradictory news of the day.

According to a new study, losing weight can be bad for you, and the longer you lose weight, the worse it is.

An international team of scientists found that toxic pollutants, which are stored in fat, release themselves into the bloodstream when fat dissipates.

The chemicals, called persistent organic pollutants (POPs) are linked to degenerative diseases like rheumatoid arthritis, hypertension, and type 2 diabetes, the study's lead author Duk-Hee Le told Reuters Health.

Lee's team followed 1,099 American participants, tested their blood, and found concentrations of seven potentially harmful POPs.

Subjects who lost significant weight over the course of ten years were compared to those who gained or maintained a steady weight. The "Biggest Losers" had the highest concentrations of POP's.

More studies are needed to establish if such harm outweighs the benefits from weight loss, Lee, who hails from the Kyungpook National University in Daegu in South Korea told Reuters.
