Health Care Is the Largest Industry in the US by Total Spending and Employment

• Spending growth reflects system use more than price spikes — A central takeaway is that overall demand for medical services stands as the largest contributor to spending increases, not price growth alone. Prices rose 2.5% in 2024, below overall inflation at 2.9%, meaning the system grew because more medical care occurred — more visits, more procedures, more long-term management — rather than dramatic price surges.

• Per-person spending growth explains why costs feel relentless — Per-capita spending reached $15,474 and has increased every year since 2000, rising 77% faster than inflation over that period. This statistic translates into a practical reality: even when general inflation slows, your health expenses continue to climb faster than most other household costs.

The pattern reflects structural expansion — population aging, chronic disease management, technology adoption — which steadily increases how much care each person consumes.

• Health care dominates national spending categories — Another key detail shows health care spending exceeds spending on housing, groceries, national defense, and vehicles. That comparison clarifies scale in everyday terms. When the largest slice of national spending flows into one sector, it shapes labor markets, policy decisions, and employer compensation. You experience that indirectly when wages shift toward benefits or when insurance design changes to manage rising costs.

• Non-medical costs expand total spending — The report identifies $768 billion spent on non-medical health expenses, representing about 15% of total health care spending. Non-medical costs include administration, logistics, and system overhead — meaning money that doesn’t go directly to treatment still drives overall spending growth.

This helps explain why system complexity matters to your wallet. More layers, more coordination, and more administrative processes increase total cost even without additional clinical care.

• Funding flows reveal why the system feels complicated — Most health care funding originates from individuals through out-of-pocket payments, insurance premiums, taxes, and employer contributions that substitute for wages. Yet that money moves through multiple intermediaries — government programs, insurers, and employers — before reaching providers.

You pay, but the path between payment and care passes through many hands, which increases complexity and reduces transparency.

• Consumer anxiety reflects structural cost pressure — Polling cited in the report shows 66% of Americans worry about affording insurance premiums and medical bills, and 55% report rising health costs in the past year. Health expenses rank as a greater concern than utilities, food, housing, and gasoline, which highlights how strongly spending trends affect daily life. This emotional dimension matters because financial stress influences health behavior, care delays, and preventive choices.

• The findings translate into actionable awareness for you — Understanding that demand — not only price — drives spending growth changes how you evaluate prevention, lifestyle decisions, and long-term health strategy. When more care equals more spending, reducing disease burden becomes financially meaningful, not only medically important. Your daily choices influence how often you rely on the system.

1. Build cellular energy as your first priority — Your mitochondria — the parts of your cells that generate energy — sit upstream of nearly every disease pathway. Think of mitochondria as your body’s power grid. When the grid weakens, every system that depends on electricity — your immune cells, your repair crews, your inflammation regulators — starts running on brownout mode.

When mitochondrial function declines, everything downstream suffers, and chronic symptoms that once would have resolved on their own become permanent fixtures.

So, how do you support them? Start with daily sunlight exposure — not through a window, but direct outdoor light, ideally in the morning. This sets your circadian rhythm, which governs mitochondrial efficiency. It’s important to avoid intense, direct sunlight during peak hours (typically 10 a.m. to 4 p.m. in most regions), however, until you’ve eliminated seed oils from your diet for at least six months.

This is because stored linoleic acid (LA) — the polyunsaturated fat found in seed oils — in your skin increases your risk of sunburn. Also prioritize consistent sleep timing, because irregular sleep disrupts the very cycles your cells depend on to repair and regenerate. Aim for the same bedtime and wake time within a 30-minute window, seven days a week.

And make sure you’re eating enough healthy carbohydrates — around 250 grams daily for most adults, and more if you’re physically active — because glucose is the preferred fuel for clean adenosine triphosphate (ATP) production, the energy currency your cells depend on to power every function in your body. Glucose generates energy with fewer damaging byproducts (reactive oxygen species) compared to burning excessive amounts of fat, especially the LA found in seed oils.

Lorsque cellular energy improves, many people are able to reduce their reliance on medications, cut back on doctor visits, and resolve symptoms they had been managing for years. That’s real spending reduction, starting at the cellular level.

2. Reduce the drivers of chronic disease — Chronic disease is the main reason people use the health care system repeatedly. It’s not acute injuries or infections driving the spending numbers you just read — it’s the slow accumulation of metabolic dysfunction that turns into diabetes, heart disease, autoimmune conditions, and cognitive decline.

Every one of those conditions requires ongoing management, medications, specialist visits, and procedures. That is where much of the demand comes from.

It’s important to identify the biggest contributors in your own life. Ultraprocessed foods top the list — they damage your gut lining, spike insulin, and create systemic inflammation. Seed oils like soybean, canola, corn, and sunflower oil are found in nearly every packaged and restaurant food, and they’re high in LA, which embeds in your cell membranes and fat stores where it promotes oxidative damage long after you’ve eaten it. Replace them with stable, traditional fats: tallow, ghee, or grass fed butter.

Beyond diet, look at your movement and sleep. Sedentary behavior accelerates metabolic decline faster than many people realize. Walk every day, ideally for one hour — not as exercise, but as a baseline for human function. Build muscle through resistance training, because muscle is your largest metabolic organ and acts as a glucose sink that protects against insulin resistance.

Track simple, inexpensive markers like your resting heart rate (lower is generally better), and HOMA-IR, which tells you how insulin-resistant you’re becoming. These numbers reveal your trajectory before disease shows up on a scan.

3. Strengthen metabolic resilience to reduce your reliance on the health care system — If you find yourself frequently sick, persistently fatigued, or dependent on a growing list of prescriptions, metabolic resilience is the lever that changes your relationship with the health care system. Resilience means your body handles stress, recovers from illness, and maintains stable energy without constant medical intervention.

Protein intake is foundational here. I recommend about 0.8 grams per pound of ideal body weight, or 1.76 grams per kilogram — with one-third from collagen-rich sources like bone broth, slow-cooked meats with connective tissue, or a quality collagen supplement. Collagen provides glycine and proline, amino acids that many people are deficient in, which support gut integrity, joint health, and liver detoxification.

The remaining two-thirds should come from complete protein sources like pastured eggs, grass fed beef and dairy. When it comes to carbohydrates, if you’ve been low-carb for a long time and your metabolic markers have stalled or worsened, consider restoring carbohydrate tolerance gradually. Start with whole fruit and white rice.

As your tolerance improves, you can expand into well-cooked root vegetables, then non-starchy vegetables, starchy vegetables like sweet potatoes or squash, beans, legumes and, finally, minimally processed whole grains. Stable metabolism means fewer doctor visits, fewer medication adjustments, fewer emergency situations, and fewer long-term interventions. That is how you personally reduce the demand side of the spending equation.

4. Question the default path before it becomes your spending pattern — The health care system isn’t designed to ask whether you need less of it. It’s designed to deliver more. More referrals, more follow-ups, more imaging, more prescriptions — each one reasonable in isolation, but collectively they become a spending pattern that is very difficult to reverse once it starts.

I’m not telling you to avoid doctors or ignore symptoms. What I am telling you is to become a more deliberate participant in your own care. Before accepting a new medication, ask what the plan is for getting off of it or if nondrug alternatives exist. Before agreeing to a recurring appointment, ask what markers would indicate you no longer need it.

Before filling a prescription for a symptom that appeared after you started another prescription, pause and consider whether you’re treating a side effect with another drug — because that cascade is one of the most common ways people end up deeply embedded in the system.

This is where your own knowledge becomes your greatest asset. When you understand how your body works — what drives inflammation, what supports recovery, what your labs actually mean — you stop being a passive recipient of care and start making informed decisions about when the system serves you and when it simply generates more utilization.

That shift in mindset is worth more than any single intervention, because it changes your relationship with the largest industry in the U.S. from one of dependency to one of selective, strategic engagement.

5. Lead a healthy lifestyle that lowers demand for medical services — This is the most powerful solution, and it’s the one that directly addresses the central finding of the research: service demand is the primary driver of health care spending. Every improvement you make in your daily habits reduces how often you need care, and that’s what bends the cost curve — not for the system in the abstract, but for you personally.

Move your body every single day. Eat whole foods that your great-grandparents would recognize. Support your gut health by eating enough to maintain your metabolic rate — and be cautious about loading up on fiber before your digestion can handle it, because undigested fiber feeds bacterial overgrowth and worsens the problems you’re trying to fix.

Avoid alcohol, which damages your gut lining, disrupts sleep architecture, and burdens your liver with a toxin it has to prioritize over everything else. Maintain and build muscle mass throughout your life, because sarcopenia — the age-related loss of muscle — is one of the strongest predictors of frailty, hospitalization, and long-term care dependence.

Every one of these choices reduces your interaction with the system that just hit $5.3 trillion. You can’t control what happens at the policy level, but you can control the single biggest variable in your own health care costs: how resilient and metabolically healthy you are. That’s not a small thing. In an industry built on utilization, the most radical act is needing less of it.
