HFCS might be indirectly responsible for weight problems, but that's only because of its prominence, low price, and calorie dense-ness. Not some voodoo reason as this article states and as many believe.

The experiment's conclusions don't make sense either. There are dozens and dozens of studies showing ONLY net calorie intake is what is responsible for weight gain or weight loss, not the contents of what they eat: http://examine.com/faq/what-should-i-eat-for-weight-loss.htm...
So for the study to refute the conclusions we have arrived at today would be quite the breakthrough. Not to mention the whole part where it violates the laws of thermodynamics.
Can anyone link to a study (not an article) showing HFCS causing more weight gain in a calorie-controlled study that accounts for water weight and (preferably) doesn't have the people count their own calories?
