Peaches GeldofPeaches Geldof is reportedly on a new healthy-eating obsession after thinking she looked too heavy in the first scenes shot for her new reality television show.

The socialite is currently filming a fly-on-the-wall series for MTV which sees her acting as an editor on a magazine but is worried about the old adage that the camera adds ten pounds.

A source told the Daily Mail: “Peaches has totally cut out fast food from her diet and has lost a lot of weight.”

“When she saw herself on screen during playbacks of the pilot she vowed to lose some weight.”

“She used to eat a lot of burgers but has sworn she will resist them from now on.”
