Celebrities are a different breed when it comes to crazy diets. Like footballer Tom Brady and model and actress Gisele Bunchden’s extremely lean meal plan. Or actress Kate Hudson’s high-alkaline diet. And TV personality and designer Kristin Cavallari’s strict non-processed food regimen. But just a couple days ago, actor and producer Matt Damon took part in a Reddit AMA, in which he revealed just how he lost 60 pounds for ‘Courage Under Fire’ back in 1995, his insanely amazing taco recipe, and his opinion on the still-hot debate: Are hot dogs sandwiches? He lost a tonne of weight just by eating chicken! “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. That was the most physically challenging did I’ve ever had to do in my life. I weigh probably 190 pounds right now, and I weighed 139 in that movie, and that is not a natural weight for me and not a happy weight for me even when I was 25.” So what was his big secret to dropping all those pounds? “I had to run about 13 miles 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.” He’s really, really passionate about tacos. After one fan asked what the ingredients of his ideal taco where, Matt was taken back for a minute. “Oh my god. Fantastic question,” he wrote. Then he admitted that the quintessential taco is one he’s not supposed to have, the one he makes on taco night at his house. It’s the crunchy corn shell with the good meat, just ground beef in there, he wrote. It’s all about the layering. The meat’s got to be hot, and the cheese goes on first so that it melts. And then you’re going to get in there with a little bit of tomato and lettuce but not too much cause it’s not a salad, it’s a taco, and then you’re going to throw some avocado on top and some sour cream.
