Karl Vinson Loses 300 Lbs. Without Surgery Or Medication! 

 Karl Vinson is one of very few people in the U.S. to lose more than 300 pounds without surgery or medication. Here’s how he did it.

 When Jannah and I first met Karl Vinson about six years ago, we were all singing karaoke at O’Brien’s Irish Pub in the Wesley Chapel Village Market. 

Sometime after Jannah and I sang, up to the microphone stepped a very large man with a beautiful voice who attracted attention both for his singing and his size. 

At that time, Karl weighed close to 500 lbs. — about 485 at his heaviest — and it was hard not to notice him. He was always super-nice, but kind of quiet and kept mostly to himself. Despite his clearly professionally trained singing voice, it was obvious that Karl wasn’t particularly interested in too much interaction with others in the bar, but he was always friendly when spoken to and we couldn’t help but wonder what his life must be like, as neither of us had ever really gotten to know anyone his size before. 

Karl says that it wasn’t until a couple of years later that he visited his cardiologist, who asked him to bend down and touch his toes while being hooked up to a heart monitor. 

Well, not only could he not do it, the monitor showed Karl basically flat-lining when he was all the way bent over. “The doctor told me that if I didn’t get serious about losing weight, that appointment would probably have been my last,” Karl says. “He told me, ‘Someone is going to find you face down with your teeth knocked out and you’d likely already have been dead before you ever hit the floor.” 

He says that was finally the wake-up call he needed to at least start getting serious about dropping some of his weight. The successful long-time studio musician with Atlantic Records said that he was otherwise happy with his life and honestly wasn’t ready to lose it. 

Although Jannah and I haven’t spent as much time at O’Brien’s the last couple of years as we did when we first met Karl, we were impressed almost two years ago at how much weight he had lost at that time. Although he never mentioned his weight loss when we chatted with him then, Karl told me recently that he was probably “only” down about 90 lbs. at that time and that he hadn’t “really gotten serious about it yet.” 

I tried to explain to him that even 90 lbs. is a tremendous amount of weight for anyone to lose, but when he countered when we saw him a couple of weeks before we went to press with this issue that he was now closing in on a 300-lb. weight loss, I knew — especially at this time of year when most people are packing on a few extra holiday pounds — that I wanted to tell his story in these pages. 

Quite honestly, if the karaoke jock at O’Brien’s didn’t announce his name, Jannah and I agreed that we would not have recognized our friend Karl at all. But there he was, with that still-angelic voice, singing a Stevie Wonder tune. 

‘So, How Did You Do It, Karl?’ 

Of course that was my first question for him and I was stunned to find out that Karl had not had lap band or gastric bypass surgery, nor had he been taking any kind of weight-loss medication. That means no appetite suppressants, no semaglutide, none of it. Although I couldn’t find any statistics as to how many people have ever been documented as having lost 300 or more lbs., I did find a stat that said that of all the people who had ever lost 300 or more lbs., only 0.05% of them — or 1 in 200 — had done so without surgery or medication. 

“I wasn’t a fat kid,” Karl, 56, says. “But, when I hit puberty, I put on about 70 lbs. in a month or two. Even my doctor assumed that I started overeating.” 

However, he says, back then, doctors didn’t do metabolic profiles to determine if there is a medical cause for a patient’s extreme weight gain. It wasn’t until he started seeing his cardiologist here 4-5 years ago that anyone had ever determined that he had an enzyme deficiency that had been keeping him from being able to metabolize carbohydrates, “and carbs had always been my favorite foods, especially any kind of bread.” 

So, even though he didn’t want to have to take weight-loss medication, Karl’s doctor did put him on a medication to help him better metabolize his carbs, and once he began reducing his intake of them — as well as the number of calories he was eating every day — “the weight really started to come off.” 

Even so, he said, he’s had quite a few plateaus and other things that have happened to him that could have sabotaged his efforts. 

“I ‘only’ lost about 130 pounds total the first two years,” he says. “I knew I needed to try something else.” 

Something Else: EoS Fitness 

Knowing that he needed to get even more motivated, Karl started working out with a personal trainer and that helped him lose more weight for a while. 

But, Karl says, it wasn’t until he pre-joined the new EoS Fitness gym on Argosy Dr. (at S.R. 54, about a mile or so west of the Tampa Premium Outlets) in Lutz, near his Carpenter’s Run home, that he really found the motivation he needed. The local EoS Fitness opened in Dec. 2022 and a year later, Karl had dropped the additional 168 lbs. he needed to reach his goal of a 300-lb. weight loss. 

And, Karl says, he attributes it all to one person: EoS trainer Ally Murphey. Just like Karl, if you never met Ally before, you’d never be able to guess that she had lost more than 150 lbs. herself. 

“Yes, it wasn’t too long ago that I weighed more than 300 lbs.,” Ally admits. “And, I also lost my weight without surgery or taking any weight-loss medication.” Karl says that Ally’s success story, her encouragement and her outstanding personal training are the main reasons he’s been able to achieve his goals. 

“I’m even going to use the same surgeon Ally used for her abdominoplasty (the surgery people who lose large amounts of weight need to tighten their loose skin),” Karl says. 

“The recovery from that surgery is really tough,” Ally admits. “You basically have to stay in bed for a month and can’t do any type of exercise. But it’s worth it.” 

The Weigh-In 

When Karl told me that he was pretty confident that he would be able to get to his 300-lb. weight-loss goal in time for me to tell his story in this issue, I looked at a man who was basically a third of the size of what he was when I first met him — and didn’t doubt him for a second. He says that even though he does have a lot of loose skin around his belly, he feels — and knows that he looks — so much better. 

“I did a recent tour with the rock band Sabotage in Japan,” he says. “We walked all day one day around some famous gardens. I walked more than 12 miles that day and never felt out of breath. Two years ago, I couldn’t have made it two blocks without having to sit down.” 

As for that all-important weigh-in itself, he says, “Everyone at EoS wanted to be there when I got to being down 300 pounds. They’ve all been so supportive.” 

The 42,000-sq.-ft. fitness facility erupted in applause when the scale showed that Karl weighed 180.2 lbs. — and he was still wearing his sneakers and sweat-soaked gym clothes. “And I’m down another two lbs. since then,” he says. 

He had already done an hour of weightlifting and an hour on the bike, as he does four days every week. His diet these days consists mainly of vegetables, chicken and fish and he says he rarely eats red meat anymore. 

“I also eat a lot of hummus,” Karl says. “And, when I do eat some carbs, I’m very careful to control my portions.” 

Everything he’s been doing has worked so well, in fact, that he no longer needs medication to control his adult-onset (Type II) diabetes, his cholesterol or his blood pressure. 

“But I will be on medication to control my irregular heart rhythm (tachychardia) for the rest of my life,” he says. 

The Mental Side Of It 

One of the hardest things for Karl about his weight loss has been his own head. 

“I was so big for so long that whenever I would go out to eat, I’d always ask to not be seated at a booth, because my stomach couldn’t fit under the table at a booth. I no longer have that problem, but it took me a long time to stop worrying about where I would be seated.” 

It also has been super-difficult for him to stop having to wear nothing but loose-fitting black clothes. 

“I’m wearing size 36 pants now,” he says. “But I was a 7XL at my biggest. I’m finally buying myself some clothes at Men’s Wearhouse. It’s just really hard to not still think of myself as a fat person.” 

As a studio musician who has been under contract for 35 years with Atlantic Records and its parent company (Warner Bros.), Karl has gotten to work with — and contribute at least snippets of songs to — a number of famous artists. In other words, despite his weight, he has led an extremely interesting life. He says he still writes about 30 songs every month. 

And, he adds, music is a big part of how he has been able to survive being so overweight for so long. 

“One of the reasons I’ve spent so much time singing karaoke the last few years is because singing has really helped me with my breathing. Being extremely overweight makes it really hard to breathe and singing has definitely helped me.” 

Of course, losing 300 lbs. has helped perhaps most of all and has surely added years to Karl Vinson’s life. He is supposed to be making an appearance at some point with WTVT-TV Fox-13’s Charley Belcher. But, in the meantime, I hope that anyone reading this who is struggling with their weight will see that it’s true that anything is possible. 

“If I can do it, anyone can,” Karl says.
