At his heaviest, 'Lean Back' rapper Fat Joe was upwards of 400 pounds, and the Terror Squad member was sincerely afraid for his life. Obesity is a life-threatening condition, and Joey Crack knew he had to get himself into shape or he would ultimately have to face the consequences.

Back in 2011, Fat Joe began losing his excess pounds the good old fashioned way, through dieting and exercise. Now, the rapper looks fitter and happier than ever, and is a source for other people struggling in similar situations. In Jan. 2012, Joe told MTV, "I was at a party New Year's Eve and, no lie, at least 10 different people came up to me. One guy was like, 'I lost 30 pounds because of you.' ... It's all about education and knowledge, feeding yourself and knowing that too much carbs is what gets us fat."

But just because Fat Joe, who will not be changing his stage name, is eating healthier doesn't mean that his mindset has changed. "I'm fat at heart," the rapper said in Nov. 2011 (via Starpulse). "I really wish I could go and eat 30 Big Macs... But I don't wanna die, so I'm trying to eat right."
