9. Matthew McConaughey – ‘Dallas Buyers Club’
We are so used to seeing Matthew looking super handsome that we were all in shock when we saw ‘Dallas Buyers Club.’ McConaughey played a man diagnosed with HIV and had to go through a dramatic weight loss. But unlike Bale, McConaughey was regularly meeting a nutritionist, who helped him lose weight in a healthier way. Besides dieting, the actor was also doing cardio. He dropped 47 pounds in just four months.
