Conventional Medicine vs. Functional Medicine

Conventional medicine waits until you are sick, then intervenes. Functional medicine acts early, keeping you healthier for longer.

You're Doing Everything Right. The Scale Disagrees.

When the weight won't move no matter what you try, it usually isn't about effort. Each of these points to a metabolic or hormonal shift that shows up on the right lab work. If nobody has tested you properly, the real reason is still hidden.

If you are experiencing any of these, we can help.

Medical Weight Loss, Built Around Your Labs

Generic diets treat everyone the same, so they fail the moment your biology doesn't cooperate. Med Matrix starts with what's actually happening inside your body, then builds a medically supervised plan around it. Here's what that looks like.

🧬

Find the Real Reason

Stubborn weight is usually a symptom, not the problem. Thyroid issues, insulin resistance, hormone imbalance, high cortisol, and nutrient gaps can all stall your metabolism while standard labs look normal. We test 80+ markers so your provider can see what's really going on before recommending anything.

80+ hormone, thyroid, and metabolic markers Reads results against optimal ranges, not just normal Finds causes a standard panel misses No guessing, no one-size plan
💊

Medically Supervised Options

For some patients, GLP-1 medications are one tool a licensed provider may include in a personalized plan. When they fit, they're prescribed and monitored by your medical team, dosed to your situation, and paired with lab work, nutrition, and regular follow-up. They're one part of a complete plan, never a standalone quick fix.

Prescribed and monitored by licensed providers Considered only when appropriate for you Paired with labs, nutrition, and follow-up Adjusted to how your body responds
🥗

Nutrition & Metabolic Support

Starvation backfires. It slows your metabolism and burns the muscle you need to keep weight off. Your plan supports metabolic health with realistic nutrition, targeted supplements where your labs show a gap, and changes you can actually live with.

Realistic nutrition, not crash dieting Supplements targeted to your lab gaps Protects the muscle that keeps weight off Built for your life, not a 30-day sprint
🔁

Keep It Off

Most programs end the day you hit a number, which is exactly why the weight comes back. We retest your labs, track body composition, and adjust your plan over time so progress holds. The goal is lasting change, not a number you can't maintain.

Your Questions, Answered

Because effort isn't always the problem. Thyroid issues, insulin resistance, hormone imbalance, high cortisol, and nutrient gaps can all slow your metabolism while a standard lab panel still looks normal. We test 80+ markers to find what's actually getting in the way.

For some patients, GLP-1 medications can be part of a medically supervised plan. Whether they're appropriate for you depends on your labs, your history, and a provider evaluation. They're one option we may discuss, always under medical supervision and always paired with testing and follow-up, never a standalone quick fix.

No. Crash diets slow your metabolism and burn the muscle you need to keep weight off, which is why the weight comes back. Your plan is built on your lab results and designed for changes you can actually maintain.

Yes. We run comprehensive labs before recommending anything. That's how we avoid the guesswork that makes generic weight-loss programs fall short. Your plan is built on your numbers, not averages.

Everyone responds differently, so your provider will set realistic expectations based on your labs and history. We focus on steady, lasting progress rather than fast numbers that don't hold.

Possibly. Bring what you have and our team will review it. If the panel is recent and detailed enough, we can use it. If not, we'll fill in the gaps.

Typically every 90 days during the first year. Retesting lets us see how your body is responding and fine-tune your plan.

Optimal. A normal range covers most of the population, which means you can feel stuck and still fall inside it. We look at where your levels should be for your metabolism to actually work well.

It depends on your goals, the testing you need, and what's included in your personalized plan. Our team walks you through pricing on your discovery call so there are no surprises. Many services are HSA and FSA eligible.
