The 'BBC Breakfast' host - who has been wowing the 'Strictly' judges with her routines - has shed 7 lbs in six weeks thanks to her gruelling rehearsal schedule.
"I have run marathons and half-marathons regularly, but I have never been in such good physical shape," she told the Radio Times.
"I’ve lost more than half a stone, and parts of me that were fleshy seem to be disappearing – other parts remain fleshy, and it’s a shame I don’t have a choice which bits go and which stay,” she added.
However, not every celebrity dancer on the show has had the same results - Abbey Clancy recently revealed she's put ON weight.
"I’ve actually gone heavier, I think it’s muscle," she said on ITV show 'Lorraine'.
"We eat so much, you have to because you need the energy and you’re so tired if you don’t."
