Metabolic Health in Philadelphia, PA: The Numbers That Matter Years Earlier

The standard metabolic workup in Philadelphia primary care runs roughly: fasting glucose, HbA1c, lipid panel, blood pressure at the visit. If everything is "normal," you are told to keep doing what you are doing. If anything is borderline, you might get a "watch your diet" conversation and a six-month follow-up. That workup is roughly two decades behind where the metabolic science actually is. By the time HbA1c crosses 5.7% (the cutoff for prediabetes), the upstream pathology has been progressing for years. Fasting insulin moves earlier than glucose. Visceral adiposity precedes both. The lipid panel without ApoB misses a meaningful fraction of cardiovascular risk. And blood pressure measured once at a visit is a poor approximation of what your blood pressure does over 24 hours. This page is how Fishtown Medicine in Philadelphia actually measures and treats metabolic health: the panel, the interventions, and the long-arc plan.

What "metabolic health" actually means

The classic definition (from the 2018 NHANES analysis) uses five criteria:

1. Waist circumference under 102 cm (men) or 88 cm (women).
2. Blood pressure under 120/80 without antihypertensive medications.
3. Fasting blood glucose under 100 mg/dL without diabetes medications.
4. HDL cholesterol above 40 (men) or 50 (women).
5. Triglycerides under 150.

Only about 12% of American adults meet all five. The other 88% have some degree of metabolic dysfunction, often years before it shows up in any single dramatic lab value. This standard definition is useful but incomplete. A more sensitive workup adds:

• Fasting insulin and HOMA-IR. Catches insulin resistance years before fasting glucose moves.
• HbA1c. Three-month average glucose; more sensitive than fasting alone for early dysglycemia.
• ApoB. Far better than LDL for cardiovascular risk; tracks atherogenic particle number directly.
• Lp(a). Genetic, lifetime-stable; once-in-a-lifetime test that reroutes care if elevated.
• hsCRP. Low-grade inflammation correlates with cardiometabolic risk.
• Liver enzymes plus FIB-4 calculation. Catches NAFLD/MASLD early.

What a real metabolic workup includes at Fishtown Medicine

For a first-time visit, our standard panel includes:

• Fasting insulin (often the highest-yield single test for early metabolic disease).
• Fasting glucose and HbA1c.
• Comprehensive metabolic panel including liver enzymes (ALT, AST).
• Full lipid panel with ApoB.
• Lp(a), once in a lifetime.
• hsCRP.
• TSH and free T4 (thyroid disease has cardiometabolic implications).
• Vitamin D, B12.
• CBC.
• Sometimes liver fibrosis screen (FIB-4 from existing labs).

Beyond labs, we measure waist circumference (more honest than BMI), check 24-hour blood pressure if office readings are borderline (home cuff or 24-hour ambulatory), and have a structured conversation about training, nutrition, sleep, and alcohol.

What actually moves the numbers

The interventions with the strongest evidence for improving metabolic health, in approximate order of impact: Resistance training, 2-3 sessions per week. The single most underrated metabolic intervention. Muscle is the largest reservoir of glucose disposal in the body. Building it improves insulin sensitivity, fasting insulin, and HbA1c, often dramatically. This is the intervention most patients have not seriously tried. Zone-2 cardio, 3-4 hours per week. Mitochondrial density and function improve with sustained submaximal training. Translates to better fasting insulin, better HbA1c, better lipid profile. Protein-floor nutrition. Approximately 1.6 g/kg/day of ideal body weight for active adults. Adequate protein supports lean mass during weight loss, reduces appetite, and improves body composition. Fiber and whole-food carbohydrate sources. The carbohydrate composition matters more than the absolute amount for most patients. High-fiber, whole-food carbohydrates do not drive the same insulin response as refined carbohydrates. Sleep duration of 7-8.5 hours. Sleep deprivation impairs insulin sensitivity within days. Chronic short sleep is one of the most underrated drivers of metabolic dysfunction.

Alcohol moderation. Alcohol is the most underdiscussed driver of metabolic disease in adults in their 30s-50s. Honest reduction often moves multiple metabolic markers within months. Smoking cessation. Always. Metformin, when clinically indicated. For patients with prediabetes or type 2 diabetes who have not fully responded to lifestyle. Inexpensive, well-tolerated, well-studied. GLP-1 medications. For patients with significant weight to lose, type 2 diabetes, or established cardiovascular disease with elevated BMI. See GLP-1 Weight Loss in Philadelphia for the longer discussion. Statins and other lipid-lowering therapy. Driven by ApoB-based targets, not the older LDL-based ones.

How metabolic health is managed at Fishtown Medicine

First visit is 90 minutes. We build the full picture, decide on the panel, and have an honest conversation about which interventions are realistic for this patient at this moment. We do not push a single dietary framework or training plan; we work with what the patient can sustain. Follow-up at 4-6 weeks for results review and plan adjustment. Then 3-month follow-up for first re-check of markers (fasting insulin, HbA1c, ApoB). For most patients with meaningful metabolic improvements to make, we see them at 3-month intervals for the first year. We coordinate with cardiology, endocrinology, and hepatology when relevant (advanced lipid management, complex diabetes, fatty liver requiring further workup).

What it costs

Membership at Fishtown Medicine covers all visits and ongoing management; see pricing for current rates. All visits and direct messaging access are covered. Labs are billed separately at the cheapest of insurance or cash. Medications (metformin, GLP-1s, statins) are billed through pharmacy.

Key Takeaways

• About 88% of American adults have some degree of metabolic dysfunction.

• ApoB is a better cardiovascular marker than LDL.
• Resistance training, zone-2 cardio, protein, sleep, and alcohol moderation move metabolic markers meaningfully.
• Fishtown Medicine runs the full panel and builds a real plan around what actually works.
