If someone had asked Kelly Pless to describe herself three years ago, the word fit" would have never crossed her mind. For most of her adult life, the 31-year-old ... has struggled with her weight. She started gaining as a teenager and by the time she graduated from high school, she was carrying 215 pounds on her 5' 2" frame. At 28, she started having trouble breathing and doctors told her the weight was to blame. She reached her breaking point. Pless decided to do something. Fortunately she didn't have to look far for inspiration. "My manager at the Kennedy Space Center ran marathons, and he was the same age as my father," she said. Over the next three to four months, she began walking, without any real goal or expectation. Pless believed that if she just focused on eating less and moving more, everything would fall into place. "At first, it was hard to start exercising because I was worried people would make fun of me," Pless said. "But then I just told myself, if that's the worst that could happen ... I just got out there and didn't care." She also adopted an "eat to live" philosophy and satisfied her cravings for sweets by eating lots of fruit. "After a few months of cutting [snacks and sweets] out, I focused more on portion control," said Pless. "I pretty much eat when I'm hungry and don't eat when I'm not and really try to pay attention to when those times are. Pless asks herself, "What do I really want to eat? Or, what does my body really want right now?" All of the hard work and determination paid off. Pless has lost 95 pounds and kept it off for 1 years. As a result, she says, she's healthier and more confident. Pless runs about 40 miles a week while she trains for two marathons she plans to run this winter. "Running has become a constant for me and does so much more for me than maintain my weight, which is now about 125 pounds," said Pless.
