Having bounced back into her stunning pre-pregnancy shape after only giving birth in September, Megan Fox is letting other moms in on the secret - say no to dairy.

The 26-year-old beauty says she has not been workin gout since having her son Noah, but yet she has been able to get her body back.

"I didn't do much workin gout because after you have a baby, it's very difficult to work out and I wouldn't recommend it...

'I'm not eating dairy, that's my biggest secret,' Megan said. 'It's really hard on your hormones and it's not good.'

The Transformers actress said it was simple, issuing a ultimatum to others tryting to lose their baby weight.

'If you want to gain weight, eat dairy. If you don't, don't eat it.'

Megan did not have a lot of weight to lose however. ' I only gained 23 pounds when I was pregenant and I'm still 10 pounds heavier, but I don't want to kill myself trying to get back into shape because it's not a priority right now."
