A father-of-three from Montana lost 92lbs in just 15 days and went on to even have a ripped physique and web users are impressed.
Jeremiah Peterson, 40, said he decided to change his diet and exercise habits after realizing he no longer could keep up with his three kids.

He now uses Instagram to inspire others to improve their lives by setting fitness and health goals.
Below is how he now looks.
