Meet Derek Mitchell, an inspiring 35-year-old race runner who weighs a whopping 545 pounds. Despite his heavy frame, he’s spent the past year walking and running a total of 21 5k races and two 10k events. He even made it halfway through a muddy, 10-mile obstacle course!
Mitchell, a Kansas City native, was diagnosed with a noncancerous tumor on his pituitary gland five years ago, a condition that slows down his metabolism and is the primary cause for his obesity. Although he was put on medication to shrink the tumor, Mitchell felt that “at one point, I was using that condition as a crutch, telling myself, ‘I’ll wait for the pills to start working before I start working out or change my eating habits.’”
But he realised that wasn’t a very good plan in November 2014, when his body weight reached an all-time high of 625 pounds. “That’s when I knew I needed to make a change, and decided to start with a new year’s resolution.” So in the beginning of 2015, he cut soda from his diet, switched to more nutritious food options, and tried switching to a healthier lifestyle.
