Atkins TV Spot, 'That Belt Notch'

Rob Lowe has got a notch on his belt that he absolutely does not want to use, which is why he says Atkins comes in handy -- especially the last few months. He says it allows him to eat foods that deliver healthy proteins and aren't full of sugar or refined carbs. If you feel good on the inside, Lowe says, you look good on the outside.
