Dr. Phil and Biggest Loser star Jillian Michaels teamed-up to tackle the rising epidemic of obesity in children for a shocking show that aired Friday.

The Oprah alum executed his trademark tough love approach, attacking parents for their part in the problem, and in a video clip, obtained by RadarOnline.com, Jillian rips into a parent whose 4-year-old son already weighs 122 pounds.

The concerned mother claimed to feed her son a strict diet of health food, but Jillian got to the heart of the matter. “What do you feel when you feed your son,” she asked, but the mother replied blankly: “I don’t know.”
