The Failure of the Fat Free Revolution: "....In 2011, a Purdue study hammered the final nail in the olestra coffin. It found that olestra incites weight gain by tricking the body into thinking it doesn’t need to metabolize fatty foods. Used to olestra fat without any calories, the body is surprised by the calories of the real thing.
The finding fits our current organic ethos; it would have surprised parents in the 1990s who regarded fat-free cookies and crackers as healthy. It’s only relatively recently that applying the laboratory to our food supply ceased to seem futuristic and be in vogue. Today, olestra has achieved immortality, just not in the way its inventors expected: in 2010, TIME Magazine ranked it as one of the 50 worst inventions of all time."
