Isla Fisher does not weigh herself regularly because she wants to set a good example for her daughters.
The Australian actress - who has two daughters Olive, five, and Elula, two, with her 41-year-old husband Sacha Baron Cohen - tries not to be too strict with her diet as she wants her daughters to grow up with a positive body image.
She said in a recent magazine interview that she was happy to gain weight for her role in 'The Great Gatsby'.
"I gained 15 pounds. It mainly manifested itself in my boobs, which was very exciting. Sadly, that's gone now," she said.
The 37-year-old beauty also revealed that she didn't put any pressure on herself during either of her pregnancies.
"I gained 65 pounds with my first baby and 70 with my second", she said. "I mostly ate supersize bowls of white pasta with loads of butter and cheese, late night cornflakes, Haagen-Dazs ice-cream and scones with jam and cream."
She claims she got her back to her pre-pregnancy weight with the help of a personal trainer and breastfeeding but insisted she is not concerned if her stomach is never completely flat again.
"Even though it will never be flat again, it's still my favourite because it reminds me f my greatest achievement: my babies."
