Jake Gyllenhaal – Low-Calorie Diet/20 Pounds

When Jake Gyllenhaal was set to star in the movie Nightcrawler, he was told he had to shed some pounds. He needed to be very thin for his starring role so he later made sure his meals had minimal calories. Barely able to eat anything appetizing, Gyllenhall remained determined and was able to drop 20 pounds. It was worth it because his performance in the movie earned him a number of awards and award nominations. Gyllenhaal is going to be playing Mysterio in the upcoming Spider-Man: Far From Home movie, in 2019.
