Brooklyn Decker's father staged an "intervention" to stop her worrying about her weight.
The 23-year-old Victoria's Secret model admits she was "freaked out" when she first started modelling because of the extreme measures other catwalk beauties used to stay in shape and felt she also had to try strict diets.
My father did an intervention and got me to stop obsessing about everyone else and wrecking my body.
She explained to Self magazine: "I was always with other aspiring models. There were bingers and purgers, and everyone watched each other eat. It freaked me out. I did juice fasts and crazy diets and ended up gaining weight.

Brooklyn - who is married to tennis star Andy Roddick - recently made her movie debut in romantic comedy 'Just Go With It' and admits she surprised her co-stars Jennifer Aniston and Adam Sandler with her less-than-glamorous appearance.
She explained recently: "When people hear 'bikini model' they have one thing on their mind.
"Then they see you're someone who shows up to the set in pyjamas and no make-up, watches sports and belches."
Brooklyn thinks the role in the romantic comedy is the perfect way for her to start off in the movie industry.
She said: "'Just Go With It' has just wrapped and it's definitely the most exciting thing I've done. It was a big first for me. It really opened up a whole new field for me to go into, and I just felt really lucky to go to work on such a big movie. It was really cool to be a part of that and learn the process of acting."
