Does that knock your hat in the creek, or what?
Perhaps this is at least part of the explanation for why people who lose weight, tend to gain it back, even when they try hard to prevent it. (It seems that Mother nature does indeed know best).
Long-term weight loss may release into the blood industrial pollutants linked to illnesses like diabetes, hypertension and rheumatoid arthritis, researchers said on Tuesday.
These compounds are normally stored in fatty tissues, but when fat breaks down during weight loss, they get into the blood stream
"We are living under the strong dogma that weight loss is always beneficial, but weight gain is always harmful...but we think that increased (pollutant) levels (in the blood) due to weight loss can affect human health in a variety of ways," she wrote in an email to Reuters.
Those who lost most weight over 10 years had the highest concentrations of the compounds, called persistent organic pollutants (POPs), compared to those who gained or maintained a steady weight.
"There is emerging evidence that POPs ... are not safe. POPs (are) linked to type 2 diabetes, hypertension, coronary heart disease, rheumatoid arthritis, periodontal disease," Lee said.

One thing is for sure, this is likely to be a very controversial topic, in the future, unless the medical community chooses to sweep it under the rug, (as they sometimes choose to do).
