Are all calories created equal? Why is that last half stone so hard to lose? What’s the healthiest evening snack you can eat? These are just some of the questions that Karl Henry, he of Operation Transformation fame, has the answer to in this episode.

Karl and I also tackle a couple of trickier subjects, like should we really be telling people its ok to be obese if that’s what they want to be, or is it now taboo to call someone fat, and should the word be banned?

You can watch Karl on Operation Transformation every Wednesday at 21:30 on RTÉ One and on the RTÉ Player.
