I am maintaining a 30+ pound weight loss at around 120 lbs.
After putting on about 25 lbs in college due to foot surgery that kept me from running and out-of-control portions of "healthy" food, by graduation I was ready to take control of my life and make health my top priority.
My husband, then fiancé, and I spent a year cooking healthy meals and exercising everyday. He lost 30 pounds in 3 months; it took me a year and a half.
Now, -30ish lbs later, I'm the healthiest - and happiest - I've ever been.
