Getting sick after reaching your goal weight...

Yes they may sell stuff on the following page, but the article is still relevant.

Who are "they"?

It turns out that "they" is the the certified nutritionist that wrote the article.

The author of the article is also the founder and owner of the Wellness Resources, Inc.

The person writing the article stands to make a profit if you believe that his products will clear your body of toxins.

Perhaps that one is ok?

"Action Points

Point out that observational, cross-sectional studies cannot determine causality.
Note also that the study did not examine whether there were deleterious health consequences due to changes in serum levels of organic pollutants that apparently were released from fat cells as a result of weight loss."

and

"Since most of these pollutants turned out to be undetectable in many samples, Lee and colleagues focused on the seven with the highest detection rates in participants who were at least 40 years old. The study group was comprised of 49% men and over half were white."

that is an extremely small sample size. they were able to cull out 7 people that supported their theory and they are not able to prove why their levels were higher.. there are all sorts of exposure routes for toxins.

and finally

Lee and colleagues acknowledged that the study design allowed for potential confounding and error, insofar as each participant had only one serum measurement of pollutant levels and reported their own previous weights.

all adding up to not a very through study. Certainly not enough information to draw any sort of conclusion and try to spit it out as a new found fact.
