But there is a catch as to how he is able to maintain that nice physique of his.
When Nick was just 13-years-old, he was diagnosed with Type 1 diabetes.
Since being diagnosed, he had to make a huge cut back on his sugar as well as staying away from soda.
The 20-year-old Jonas recently took to the Internet to post his pic, also writing:
“I never do this but…Healthy living and fitness update. Post workout picture. #diabeticinshape #2.0.”
Nick also told Good Housekeeping mag in 2011 that he eats a lot of eggs since its good for him, and gets into the gym as much as possible.
We credit you Nick for staying strong and keeping up that great bod despite your disease. True soldier!
