From the Mats to Mastering Diabetes: How BJJ Fighter Ronnie Tannariello Turns Challenge into Championship Mindset
In the world of combat sports, we’re used to seeing athletes battle opponents, but some warriors fight invisible enemies every day. Ronnie Tannariello, a Brazilian Jiu-Jitsu athlete from Coral Springs, Florida, brings a whole new meaning to the fighter’s spirit as he grapples not just with opponents on the mat but with Type 1 diabetes – a condition that demands as much strategy and discipline as his sport.

The Submission Artist Who Won’t Submit to Diabetes
When most BJJ practitioners worry about their next competition or perfecting that tricky sweep, Tannariello has another variable in his training equation: blood sugar management. Yet watching him on the mats, you’d never know he’s constantly monitoring an internal battle while executing external ones.
“Every roll is actually two fights,” Tannariello told me during our conversation at his local gym. “I’m fighting my opponent and I’m fighting to keep my glucose levels stable. Sometimes the second fight is tougher than the first.”
The Diagnosis That Changed Everything (But Stopped Nothing)
Diagnosed with Type 1 diabetes early in life, Tannariello could have easily stepped away from the physically demanding world of combat sports. Instead, he doubled down, using the discipline required to manage his condition as a foundation for his training regimen.
“People see diabetes as a limitation. I see it as my secret weapon,” Tannariello explains. “The attention to detail, the strict discipline, the constant body awareness – these are all things that make you a better fighter anyway.”
Managing the Invisible Opponent
For those unfamiliar with Type 1 diabetes, it’s an autoimmune condition where the pancreas produces little or no insulin, requiring careful monitoring and management. For a BJJ athlete, this adds layers of complexity:
- Glucose monitoring before, during, and after training
- Timing insulin doses around workouts
- Strategic nutrition planning for optimal performance
- Preparing for how adrenaline affects blood sugar during competition

The Florida BJJ Scene Takes Notice
The South Florida Brazilian Jiu-Jitsu community has embraced Tannariello not just as a skilled practitioner but as an inspiration. Local tournaments now often see him competing alongside other athletes who’ve approached him for advice on managing health conditions while training.
His coach at Coral Springs BJJ, Marcus Santos, puts it simply: “Ronnie doesn’t use diabetes as an excuse – he uses it as motivation. That mentality spreads through the whole gym.”
| Challenge | Tannariello’s Approach |
|---|---|
| Low blood sugar during training | Strategic carb intake before sessions; glucose tablets on standby |
| High-intensity competition effects | Adjusted insulin dosing on competition days; frequent monitoring |
| Recovery considerations | Specialized post-training nutrition; extended cool-down routines |
| Travel for tournaments | Detailed planning for supplies; time zone adjustments for medication |
Lessons for All Fighters
What makes Tannariello’s story relevant even to fighters without diabetes is the mental framework he’s developed. His approach to obstacle management translates directly to fight strategy: identify the problem, develop a game plan, execute with precision, and adjust when necessary.
“The biggest similarity between managing diabetes and BJJ is that both are about constant adjustment,” Tannariello says. “You don’t just set a plan and stick to it blindly – you read feedback from your body or your opponent and make micro-adjustments constantly.”
Beyond the Competition
Tannariello has begun holding seminars specifically for combat sports athletes with chronic health conditions. These sessions combine technical BJJ training with practical advice for managing health challenges during intense physical activity.
“I’m not just building a competition record,” he explains. “I’m trying to show that the fighter’s mindset works beyond the gym – it works for life challenges too.”

The Fight Continues
As Tannariello prepares for upcoming competitions this season, he represents a powerful reminder of what the true martial arts spirit embodies: overcoming limitations, adapting to challenges, and finding strength in what could be perceived as weakness.
For the MMA and BJJ community watching his journey, Tannariello offers this perspective: “Everyone’s fighting something you can’t see. Mine just happens to have a name and numbers attached to it.”
