Aidan Dewar

The through-line

Dewar's argument starts with a diagnosis and never leaves it: the American healthcare crisis is a chronic condition crisis, and the chronic condition crisis is a nutrition crisis. He points out that the country spends roughly 20% of GDP and over $4 trillion on healthcare, more than any other country and more than it ever has, and is getting less for it, while heart disease, diabetes, obesity, high blood pressure, cholesterol, GI conditions and eating disorders sit at all-time highs, leaving "a generation that's sicker than our grandparents" despite technological advances everywhere else in the economy [1]. Drill down twice and the conclusion is that "all these chronic conditions are really downstream of what you eat" [1], which is why he frames the work as building a health system organised around prevention and outcomes rather than treating things when it is too late [1][6].

The second half of the through-line is that the fix already exists and is already funded. Dietitians are covered generously by commercial insurance, Medicare and Medicaid, but almost nobody knows it and the ones who do struggle to use it, so Nourish's job is to "make it easy to take advantage of that benefit" [1]. He treats nutrition and lifestyle change as one of the most underleveraged opportunities in healthcare, and has continued to argue that case as the company scaled to coverage in all 50 states and into questions of AI and system design [4][5][7].

On why he ended up here

The origin is personal rather than analytical. Dewar and his co-founders, Sam and Stephanie, had been hacking on projects together and kept returning to their own experiences with the healthcare system: Dewar had severe chronic migraines that years inside the system failed to resolve and that were ultimately solved by working with a dietitian, and both co-founders had their own journeys [1]. That frustration, and its resolution through changing what he ate, is what opened up the wider problem for him, and he is explicit that they were not the first to notice how effective dietitians are at treating these conditions, which is precisely why the benefit exists in the first place [1].

On behaviour change, not information

He is blunt that knowledge is not the bottleneck. Anyone can consult Dr Google, and the information may or may not be right, but either way "the majority of the work is not in ... learning what you need to do but actually in enacting those habits" [1]. Dietitians are world class, trained and certified at both halves of the job: educating a patient on the recommendation, then staying with them so the habits become real [1]. What determines outcomes is long-term sustainable change, not short-term interventions, and he speaks from his own experience with chronic condition and weight struggles when he says quick fixes that work for a few weeks do not matter if they do not last [1]. In practice that means the intake appointment is about understanding the patient and building a personalised care plan, while the follow-ups are about refining and actually actioning it [1].

On matching patients to the right dietitian

Dewar treats the match itself as clinical infrastructure. Signup runs through questions about health history and current problems, and an internal algorithm matches on condition but also on things he considers less obvious: what language the patient speaks and what culture they come from, so food recommendations can be tailored, and the dietitian's style, whether the patient responds to tough love or a softer approach [1]. With over a thousand dietitians and the data that comes with that scale, the goal is to route each person to the dietitian who will deliver the best outcome for them specifically [1].

On software as a second player, not the product

The platform gives patients messaging with their dietitian, meal logging, health progress tracking, integrations and condition-specific resources, and dietitians get their own version of the same tooling to manage the care they deliver [1]. But he resists the idea that the software carries the outcome. Standalone nutrition apps like MyFitnessPal are good, he says, and when it is just you using them, "single player", it is not as effective as when a registered dietitian is on the other side [1]. Asked which component makes adherence work, he answers that it is all of them, but most often it is the accountability and the coach [1].

On dietitians as employees, not contractors

Nourish employs its dietitians directly as W2 employees rather than contractors, which lets the company give them benefits, and dietitians who stay for an extended period receive equity in the business [1]. The reasoning is straightforward: the company is only as good as the registered dietitians delivering the health outcomes, so the aim is to be the best place in the country for a dietitian to work, offering remote telehealth care of a type they enjoy with patients they are good at treating [1]. The result is that hiring, like patient acquisition, has run largely on word of mouth for the whole history of the business, leaving the team's job as evaluating fit and then equipping people with software and coaching to succeed [1].

On reaching patients who do not know the benefit exists

Acquisition runs through four roughly even channels: insurance payer partners who put Nourish in front of eligible members; digital advertising across Facebook, Instagram, TikTok and Google; influencer partnerships, including Alex Morgan, who joined the company's last investment round, alongside creators focused on specific conditions such as diabetes, GI issues and eating disorders; and a provider referral team that integrates Nourish into care plans at everything from individual primary care practices to large health systems, so a doctor making a diagnosis can hand over a covered referral [1]. His stated preference is none of these. Word of mouth has always been a large channel and remains the ideal one, because people who have a great experience with their dietitian tell someone else [1]. Beyond that, the principle is meeting people where they are, judged by "what's best for the patient" rather than what is best for Nourish [1].

On proving outcomes to payers

Dewar frames measurement as both mission and commercial obligation: the internal formulation of success is "how many people do we help and how much do we help them", and the second half is the harder one [1]. Nourish collects patient-reported outcomes through the app, outcomes the dietitian records from conversations with patients, integrations with medical records, and data from third-party devices including Apple Watch, Whoop and Oura Ring [1]. That data is deliberately surfaced to payer partners to show the ROI of the care [1]. He describes the relationship as collaborative rather than adversarial, since payers already cover the benefit and already believe the outcomes are there, so the work is to "put more sophisticated numbers behind the exact impact we're having" [1].

On adding the food to food as medicine

The next step he is most excited about is integrating the food itself, including food delivery, into the product, done with payer partners who are enthusiastic about it [1][6]. His logic follows directly from his view of behaviour change: the dietitian educates and then works to embed recommendations as long-term habits, and food delivery is the final step in "bridging the gap between recommendation and ... action", so that the recommendation does not stop at advice [1]. Longer term he wants to keep investing in the feature set on both sides, patient and dietitian, alongside the food layer [1].

On GLP-1s

He treats the drugs as real but partial. Their use has exploded recently after originating as diabetes treatments, and he describes them as an important innovation that is valuable for a lot of patients, while qualifying what they can do on their own [2][6]. That qualification is consistent with his broader position that sustainable behaviour change, not a short-term intervention, is what produces durable health outcomes [1].

On the system he wants to build

Everything above is in service of replacing a reactive system with a preventative one [1][6]. He describes Nourish as a food-as-medicine platform working with national commercial payers and Medicare, with Medicaid and more on the horizon, and by 2026 coverage in all 50 states for 1:1 diet counselling and behaviour change support [1][6]. He has since extended the argument into how AI should be used to build a better healthcare system, and into nutrition and lifestyle change as the most underleveraged lever in chronic disease, positions he has taken to healthcare-innovation audiences [3][5][7], while framing the ambition as rethinking how modern medicine treats the thing it has been ignoring [4].

Takeaways

• The chronic disease crisis is fundamentally a nutrition crisis: chronic conditions are "really downstream of what you eat", and the US spends over $4 trillion, about 20% of GDP, while producing "a generation that's sicker than our grandparents" [1].
• Dietitian care is already covered by commercial insurance, Medicare and Medicaid; the business opportunity is that most people do not know the benefit exists and cannot easily access it [1].
• Information is not the constraint: "the majority of the work is not in ... learning what you need to do but actually in enacting those habits", so accountability and the coach drive outcomes more than any app feature [1].
• Nutrition software used "single player" underperforms the same tools with a registered dietitian on the other side [1].
• Dietitians are W2 employees with benefits and equity after extended tenure, on the reasoning that they deliver the outcomes and the company should be the best place in the country for them to work [1].
• Patient matching runs on condition plus language, culture and coaching style, because tailored food recommendations and the right approach change results [1].
• Outcomes are evidenced to payers through patient-reported data, dietitian tracking, medical record integrations and devices including Apple Watch, Whoop and Oura Ring, to "put more sophisticated numbers behind the exact impact we're having" [1].
• Food delivery is the intended next step, closing the gap between a dietitian's recommendation and the patient acting on it [1][6].
• GLP-1s are an important innovation valuable to many patients, but he qualifies their role rather than treating them as the answer [2][6].
