Heidi Kum Battles with her Weight

Even though she's known as having one of the best bodies in the modeling business, Heidi Klum says that she has had an ongoing battle with her weight.

"I was never a skinny, skinny type – the more I tried, the worse it was. I'd think about food more than ever," says the Project Runway hostin Britain's Easy Living magazine.

"They'd say 'You have to lose weight', and I'd be like, 'All I can think about is muffins!' " she says. "I don't want to get too skinny. I still want to have a round, womanly figure."

The mom of three, 8-month-old Johan, Henry,1, and Leni, 3 says that the key to a healthy lifestyle are doing what makes you happy and being there for your children.
