Celebrities are a different breed when it comes to crazy diets. Like Tom Brady and Gisele Bunchden's extremely lean meal plan. Or Kate Hudson's high-alkaline diet. And Kristin Cavallari's strict non-processed food regimen. But just a couple days ago, Mat Damon revealed just how he lost 23 kilogramss for Courage Under Fire back in '95.
"I think the most challenging role that I've ever had, was when I did Courage Under Fire and I had to lose all the weight that I lost on my own," he said. "That was the most physically challenging did I've ever had to do in my life. I weigh probably 85 kilograms right now, and I weighed 63 in that movie, and that is not a natural weight for me and not a happy weight for me even when I was 25."
HE LOST A LOT OF WEIGHT JUST BY EATING CHICKEN
So what was his big secret to dropping all those kilograms? "I had to run about 20 kilometers a day, which wasn't even the hard part. The hard part was the diet," he said. "All I ate was chicken breast. It's not like I had a chef or anything, I just made it up and did what I thought I had to do. I just made it up and that was incredibly challenging."
