Megan Fox has come under fire in recent weeks for appearing gaunt and skeletal in a new ad for Armani.
But the 24-year-old’s personal trainer, Harley Pasternak, has come out in her defense.
The celebrity fitness expert claims that his client struggles to gain weight because of her ‘fast metabolism’ and insists she is not suffering from anorexia.
‘She gets frustrated at times because she’s like “I need to put on weight.” So she actually weight-trains to keep on that lean muscle tissue,’ Pasternak told America’s Hollywood Life.
‘Believe it or not she has this really fast metabolism. So her training is all about body toning and sculpting. With her its really about she’s eating enough of the right things.
‘People thought, “Oh she must be anorexic,” but she’s far from that!’
But Megan’s struggle appears fairly new – she was once famous for her shapely figure which she flaunted in all its glory in the first Transformers film.
She is said to have been fired from Transformers 2 over concerns she had lost too much weight.
Pasternak, who has worked with Kate Beckinsale, Minka Kelly and Halle Berry, also talked through her workout regime.
‘The key to Megan’s abs is first of all genetics,’ he said.
‘The second is that we train her abs on all three planes. It’s not just about crunch, crunch, crunch.
‘It’s about working her body up and down and side to side and rotation. We train all three of her rectus abdominis, her obliques and her corset muscle to make sure that her abs are not just tight and strong but small. The corset pulls it all in.’
However the top trainer admits he is concerned about her losing her curves, saying: ‘Do I worry about Megan getting too skinny? Yeah!’
