About Us
Fuel by Design is a wellness practice specializing in hormone optimization, metabolic health, medical weight loss, and performance-based recovery—built for high-performing adults who want a clear, data-driven plan.
Why Fuel by Design Exists
I’m Alexis Valentino, DNP, FNP-C (Nurse Practitioner) and founder of Fuel by Design, and I believe no one should feel dismissed, rushed, or confused about their health.
After years working in healthcare, I noticed a pattern: people were told their labs were “normal,” that symptoms were just stress or age—yet they still felt exhausted, foggy, overwhelmed, and stuck. Care was rushed, answers were fragmented, and too often, the real why was never addressed.
That’s why I created Fuel by Design.
Here, we slow down and look deeper. We treat the body as a whole system—not a list of symptoms—so we can stop guessing and start building a strategy that actually fits your life.
My goal is to help you feel strong, confident, and clear—not just today, but for the decade ahead.

A comprehensive, data-led approach, built for real life
Fuel by Design combines advanced lab analysis, personalized lifestyle and nutrition strategy, and evidence-based hormone and weight-loss interventions when appropriate. We also factor in stress patterns, recovery, and nervous system regulation, because long-term results depend on how your whole system is functioning—not just willpower.
Every plan is individualized, monitored, and refined over time so your strategy stays aligned with your labs, your goals, and your life.
Patient Success Stories
For years, she struggled with weight resistance, poor sleep, anxiety, mood swings, and low motivation—despite consistent diet and exercise. After a full evaluation and comprehensive labs, we identified not only hormone imbalance, but also insulin resistance and metabolic dysfunction that had been missed. With a personalized protocol supporting hormone balance, metabolic health, and stress regulation, she regained energy, improved sleep, reduced brain fog, and began losing weight without extreme restriction—most importantly, feeling seen and supported again.
She began avoiding her children's events due to shame from weight gain and severe sweating episodes that controlled her choices. We looked beyond weight alone and identified hormonal disruption and metabolic dysfunction contributing to thermoregulation issues and fatigue. With a customized plan focused on hormone balance and metabolic health, symptoms became manageable, movement felt easier, and confidence returned—allowing her to show up fully for her family again.
Designation
After 35, a high-performing executive noticed stubborn weight gain, declining energy, slower recovery, and mental fatigue that affected work and home life. We identified hormonal and metabolic imbalances commonly overlooked in busy men and built a protocol designed to restore function and improve recovery without disrupting his schedule. Over time, energy stabilized, confidence returned, body composition improved, and he re-engaged at home—feeling like himself again.
A nurse practitioner preparing for her wedding came in with weight-loss goals after years of frustration—especially following fertility challenges and suspected hormonal issues. Our evaluation confirmed this wasn't a willpower problem; it was a systems problem. With a personalized protocol supporting hormonal and metabolic health during a high-stress season, she reached her goal sooner than expected—then became pregnant, reinforcing that even healthcare professionals benefit from a comprehensive outside perspective.
