There are many motivating reasons to slim down. Maybe you have a family history of weight-related health conditions, like diabetes or high blood pressure. Maybe you're tired of feeling short of breath. Maybe you want to ease back or joint pain, or nighttime problems like snoring or sleep apnea. Maybe you want to guarantee you're around to walk a daughter down the aisle or hold a grandchild. Or maybe you just want to be able to fit into your favorite pair of jeans again.
For Stacy Phillips, that motivation came one day when, walking across a parking lot at 268 pounds, she tripped and rolled her ankle.
Watch the video above to see why her life changed forever in that moment -- and why she has lost over 125 pounds since. "Anybody can do this," she says, "but you need to do it."
