Jason Segel – 30 LBS – Diet & Exercise

If you can recall actor Jason Segel during the first few seasons of How I Met Your Mother, he wasn’t really fit. After his assistant took photos of him that made him realize he was already getting too fat, he decided to transform his body. 

Thanks to his healthy diet monitored by his trainer, he was able to say goodbye to his old physique. Working out twice a day transformed him into a total heartthrob! Jason sported a more slim look in his film Bad Teacher starring opposite Cameron Diaz. It is estimated that he lost around 30 pounds.
