Weight Loss: Christine Calderon, 40, of Woodstock, Ga. lost 117 pounds

Current weight: 143 pounds

Pounds lost: 117 pounds

Height: 5 foot 5 inches

Age: 40 years

How long she's kept it off: She started August 2013 and reached her current weight in August 2014.

Personal life: "I am a marketing manager," said Calderon. "I'm single and have two cats; my mother and sister live locally in metro Atlanta as well. I live in Woodstock."

Turning point: "I work for a company that offers a Weight Watchers At Work program. They sent an email to see who would be interested … My father lost quite a bit of weight through Weight Watchers," she said. "Unfortunately, I lost my father in 2010. Knowing with family health history and my own personal connection with Weight Watchers I thought it was a sign … from the universe: time to take control of my health … Weight Watchers has given me a structure and platform to make healthy choices — it is more than about the weight, it's about generally being healthy."

Diet plan: Her day starts with oatmeal or an egg-white omelet with veggies and sausage. Lunch is a salad and half a sandwich. Dinner is grilled chicken, brown rice and veggies.

Exercise routine: "I do some form of exercise every day … When I got to 75 pounds, I rewarded myself with a treadmill so I could have it in my home," she said. "I am fortunate to work in a building with access to a gym. I also have a gym membership. I have also started to enjoy running. I'm going to do my first 10K: the AJC Peachtree Road Race … I did not enjoy running. I used to tell my friends the only time I would run is if someone was chasing me."

Biggest challenge: "Getting started is very difficult … You have to overcome that inertia and get the momentum going … Once you see success you get motivated and you continually push yourself."

How life has changed: "Losing weight has actually made me gain self-confidence," she said. "When you are overweight, you try to be invisible. You chose to fade into the background … I am clearly more confident and that is evidenced in my personal and professional life … I found the program that worked with my lifestyle that I could sustain and that I feel improved my life all around; not just my weight, but my physical health, my mental health, my emotional health all improved through this process … I would love for people to read [my story] and see themselves and think 'I can do that.'"
