8. Jay Cutler
Jay Cutler, the NFL quarterback, was diagnosed with type 1 diabetes while playing on the Denver Broncos. After his diagnosis, he started to use an insulin pump and removed it during his games. He eventually got used to having regular injections instead of constantly being checked for his blood glucose levels. Cutler also reduced the amount of carbs and sweets in his diet, and now focuses on eating more fruit and protein.
