Current weight: 196 pounds

Pounds lost: 64 pounds

Height: 5 feet 11 inches

Age: 42 years

How long he's kept it off: He started in January 2013 and reached his current weight in October.

Personal life: "I am a nuclear reactor inspector employed by the United States Nuclear Regulatory Commission, an agency of the U.S. Federal Government. I work in downtown Atlanta and live in Kennesaw. I am happily married to Katrina Bishop and we have two boys, Brett, 12, and Evan, 9, as well as two Labrador Retrievers," said Bishop.

Turning point: "My wife had been encouraging me to do Weight Watchers for a long time and I just said I can exercise more … I couldn't sustain that amount of exercise with eating out all the time," he said. "My weight struggle started in my late 20s while I was still in the Navy." By January 2013 he reached a turning point. "I couldn't bend over to do anything because my belly was so big, to tie my shoes it would cut my breath off."

Diet plan: He started doing Weight Watchers with his wife. "She would bag up my lunch and put the points value on each item — I didn't have a choice those first few months," he said. "I lost eight pounds a month." On a typical day, he has thin bagels and a packet of cheese grits. Lunch is fruit, flatbread with lunchmeat, cheese and lettuce, and dinner is meat and two vegetables.

Exercise routine: "When I started, it was walking," he said. Before long, he was running a mile at a local park. "I was excited when I ran the whole way." He now runs 5Ks regularly, training with daily walking and a couple of runs during the week.

Biggest challenge: Business travel is his challenge. "A lot of times you can't take food with you so I go to the grocery store as soon as I get where I'm going."

How life has changed: "I guess I feel more confident, more self-esteem, a little more social, a little more outgoing," he said. "Life has definitely changed in the fitness aspect, I make time to do that every day … I do think I have a heightened awareness of what I'm putting into my body." On Nov. 1, 2014, Bishop ran the Garden Gallop 5K in Kennesaw. "I won a medal for being the fastest runner in my age group — it was my first race award."
