Could the 'real food' reset finally bend America’s obesity cost curve?

The United States finds itself at an inflection point that extends far beyond public health and straight into the balance sheets of employers, insurers, and taxpayers. For decades, Washington’s nutrition advice has reflected good intentions paired with massive health care costs. Federal guidelines trained Americans to fear fat, treat protein as an afterthought, and normalise an ever-expanding aisle of “heart-healthy” packaged carbohydrates. The outcome is not a more productive workforce or a healthier population. It’s a nation burdened by chronic disease and the most expensive healthcare system in the world.

So, when the US government recently unveiled new 2025–2030 Dietary Guidelines for Americans with a blunt directive –“eat real food” – it signalled more than a rhetorical shift. For business leaders and policymakers focused on bending the U.S. healthcare cost curve, it may represent one of the most credible upstream interventions in years.

Start with the baseline reality: chronic conditions now affect six in ten US adults and account for roughly 90 percent of healthcare spending. More than 90 percent of American adults have at least one marker of metabolic dysfunction, whether prediabetes, obesity or hypertension. Nearly 100 million American adults have prediabetes and most of them unaware. These are not abstract statistics. They are tomorrow’s amputations, dialysis bills, early retirements, insurance claims and productivity losses already embedded in corporate forecasts.

An uncomfortable question needs to be asked: did previous dietary guidelines contribute to this crisis? Yes, the old food-pyramid, derived from incomplete 1950’s evidence, was designed with healthy adults in mind – not a population already insulin-resistant. It was also founded on the idea that the fat we eat increases heart disease risk, which is still controversial. As a result, the US diet became anchored around refined carbohydrates, creating a nation running on glucose spikes and chronically elevated insulin levels.

The new guidelines mark a meaningful reversal. By making room for higher-protein meals, fewer refined carbohydrates, acknowledging healthy fats include animal fats, and establishing limits on ultra-processed foods, they flip the pyramid entirely. If implemented seriously – across schools, cafeterias, and clinical practice – Americans may finally begin a return journey to a metabolically healthier country.

For healthcare providers, insurers and patients, that translates directly into lower costs.

We've already seen what happens when metabolic health is addressed proactively rather than downstream. In a recent Swiss Re research pilot program, we offered metabolic-health initiatives for income-protection disability claimants in the UK. The pilot highlighted the cost savings implications of proactively tackling metabolic health with a nutritionally focused programme, with just over USD 1 million claims reserves released for a USD 40k investment – a cost-savings ratio of about 20:1. These were individuals too sick to work, with multiple illnesses all linked by one common thread: metabolic ill-health. While a continent away, this programme's outcome reflects the wording in the new guidelines "Individuals with certain chronic diseases may experience improved health outcomes when following a lower carbohydrate diet."

Results like this demand attention in boardrooms as much as in public health circles. We can argue forever about whether butter belongs in the “healthy fats” box. Meanwhile, US employers face a different cost explosion: healthcare expenses climbing, disability durations lengthening, and soaring GLP-1 spending. This is an expensive downstream response to upstream nutritional failure.

A “real food” guideline will not solve American obesity on its own. But it can do something rare in federal policy: it aligns health outcomes with economic incentives. It makes nutrition easier to prescribe, easier to reimburse, and easier to integrate into the systems that fund and promote better health.

On World Obesity Day, the message is clear. The new dietary guidelines’ core message – eat real food – is neither radical nor partisan. What’s new is the federal government saying it plainly. If followed through, it could help reverse not only a health crisis, but a medical spending one as well. That is a reset worth paying attention to.
