Glenn Miller, 48, of Acworth lost 52 pounds

Pounds lost: 52 pounds

Height: 6 feet 1 inch

Age: 48 years

How long he's kept it off: "I lost the weight very quickly in only 10 weeks. I started in September 2017 and completed my goal in November," Miller said. "I have kept the weight off about nine months now."

Personal life: "I live in Acworth with my wife and two children. My son is 9 and my daughter is 6," Miller said. "I am a national sales director in the telecom industry."

Turning point: "I noticed myself getting heavier and heavier over the past few years and had been diagnosed with early onset of osteoarthritis," he said. "We are avid downhill skiers. I was skiing in knee braces because of the pain in my knees. I ended up getting pushed through the airport in a wheelchair on one of our last trips to Utah because of severe hip pain that I had never had before — I felt like my body was breaking down." He went to Nancy Masoud, a metabolism specialist at Real Health Medical (www.lockitinweightloss.com).

Diet plan: Breakfast is cottage cheese with blueberries and strawberries, or he will have a three-egg omelet with spinach, mushrooms, onions and feta cheese. For both lunch and dinner, he eats a half pound of protein with veggies. Lunch and dinner vary from a chicken Caesar salad to lean steak or rotisserie chicken with veggies.

Exercise routine: "I hate to admit this," Miller said, "but I did not exercise at all, just some light walking."

Biggest challenge: "Getting started for me was hitting bottom and just wanting to feel better. My blood pressure was high and my knees, hips and back were always hurting. I was growing out of my clothes and felt uncomfortable. The toughest part was the plateaus that happened throughout, where I was working hard at eating right and staying 100 percent on track but not losing weight. We would switch up my meals and the things I was eating. … I focused on my kids and knew that if I was able to stick to it that I would feel better and be better able to keep up with them."

How life has changed: "I now weigh what I weighed in high school over 30 years ago. … I am much more active now, have more energy, and I am almost pain-free. I haven't seen a chiropractor since October of last year, and that speaks volumes because I've had chronic back pain for almost 30 years," Miller said. "I am performing better at work and feel more clear mentally; my memory has improved dramatically. I am now skiing better than ever, pain-free, and don't use the knee braces anymore. … My friends and family can't believe I lost 50 pounds — that was 21 percent of my body weight."
