The implicit context of this thread (like with a lot of Internet nutrition discussion) is that rising obesity rates over the past half century or so indicate something has gone wrong with our diets. The author is suggesting that this could be one piece of the puzzle.
There is a lot wrong with diets in developed countries, but it's not chicken, or at least chicken is way down the list of offenders.
AIUI the biggest dietary culprit is the insidious infiltration of sugars into the foods that many people eat. Much of the prepared, convenience foods people rely on contain sugars that even dedicated label-readers may not be able to readily identify. A whole laundry list of cane sugar, sucrose, high-fructose syrup, rice syrup, honey, invert syrup, molasses, panela, muscovado, etc.
Unless they're sneaking sugars into chicken, sure doesn't seem that it would be the main problem.
