Weight loss is one of the most searched, most discussed, and most commercially active health categories in the US. According to the CDC, nearly half of American adults report trying to lose weight in any given year. The market reflects that reality: research firm Marketdata valued the US weight loss and weight management market at nearly $94 billion in 2024, with steady growth projected through the decade ahead, driven by rising demand for both behavioral and pharmaceutical solutions.
What's harder to find than market size, though, is a nuanced picture of how people are actually thinking about the journey. Nextdoor's April 2026 Weight Loss Insights Report — drawn from a survey of 1,000 US adults — offers that picture.
59% of Nextdoor neighbors are aiming to lose weight this year, 26% more likely than the general population and 16% more than last year. The intent is especially concentrated among suburban residents (+75%) and women (+54%). And based on five years of platform data, weight loss is a topic neighbors engage with year-round, not just in January — though January does see a meaningful spike as New Year's resolutions take hold.
What's driving the intent matters as much as the numbers themselves. 69% of neighbors cite improving overall health as their primary motivation, followed by feeling more confident in their body (46%) and reducing or preventing health conditions (47%). Appearance-based drivers like fitting into certain clothing came in much lower, at 24%. Year over year, health and confidence motivations are both growing: health is up 10%, confidence up 42%. For advertisers, that shift has direct implications for how campaigns should be framed.
Physical activity remains foundational, with 81% of neighbors planning to increase exercise as part of their approach. But the picture is more layered than that. 51% plan to count calories, 48% are interested in prescription medication, and 46% are considering a low-carb or keto diet.
Interest in prescription weight loss medication has grown 50% year over year on Nextdoor. Still, only 6% of neighbors believe medication alone is sufficient — 47% see weight loss as lifestyle-driven on its own, and 46% see it as a combination of lifestyle and medication. The dominant belief is that sustainable change requires the whole package.
For brands in the pharmaceutical or telehealth space, that context matters. Neighbors are open to medication as a tool; they're not looking for it to replace the work.
71% of neighbors are comfortable turning to their local community for support in their weight loss journey, 22% more than the general population. And according to Nextdoor's regression analysis, the more comfortable neighbors feel leaning on their community, the more confident they are about hitting their goals — independent of age, gender, income, and other factors.
43% of neighbors aiming to lose weight say they'll turn to Nextdoor specifically for help along the way. What they're looking for locally: group fitness and walking meetups (49%), healthy food and restaurant recommendations (44%), and free or low-cost local events (42%). This isn't a passive audience waiting to be advertised to. They're actively seeking connection and accountability within their neighborhoods.
The data here is worth sitting with. 51% of neighbors feel that advertising consistently overlooks the challenge of maintaining weight loss over time — a number that's up 20% year over year. 48% feel the mental health and emotional dimensions of the journey are underrepresented. 49% say the financial costs associated with weight loss rarely come up in ads.
That's a meaningful gap. Most weight loss advertising is built around acquisition — starting a program, buying a product, beginning a journey. The audience is telling brands that sustaining results, managing the emotional arc, and understanding the real cost of commitment are what they actually want addressed.
A few things stand out from the data as a whole. Neighbors are goal-oriented: 33% have a specific number of pounds they're aiming to lose, and most expect to hit their goals within six months. Nearly half expect to reach a decision within a few days of starting to research — which means the window between consideration and action is short.
Creative that works here leads with health outcomes, not appearance. It uses real people and real stories rather than celebrity endorsements (before-and-after imagery is viewed as inspiring by 59% of neighbors; celebrity endorsements, by contrast, are viewed as discouraging by 25%). And it speaks to the full arc of the journey — not just the start, but the months after, when motivation is harder to maintain and real-world challenges tend to set in.
Community and support-driven messaging over-indexes on Nextdoor compared to the general population (+44%). That's a signal worth heeding: this audience responds to the idea of not going it alone.
