The Obesity Action Coalition, often shortened to OAC, is a national nonprofit based in Tampa, Florida. It was founded in 2005 and holds 501(c)(3) charitable status. Where a research institute studies obesity and a medical society trains clinicians, the OAC speaks for the people living with the condition. Its stated purpose is to give a voice to the millions of Americans affected by obesity and to help them move toward better health.

Membership in the OAC is open and has grown past 85,000 people. Members include patients, family members, and the healthcare providers who treat them. This is not a fee-gated professional body; it is closer to a community, and much of what the organization does is shaped by that membership rather than handed down to it.

The work falls into a few clear streams. The first is education. The OAC maintains a large resource library covering what obesity is, how it develops, and the range of treatments available, from lifestyle change to medication to surgery. Childhood and adolescent obesity get dedicated material. The organization has also published more than 50 issues of Weight Matters Magazine, a free publication that mixes practical advice with personal stories from people in the community. Printed resources can be ordered as well, which is useful for clinics and support groups that want something to hand out.

The second stream is advocacy, and this is where the OAC has carved out a distinct identity. It campaigns on access to care, pushing for obesity treatment to be covered and recognized the way other chronic conditions are. It works against weight bias, the unfair treatment and stereotyping that people with obesity often encounter in workplaces, schools, media, and even healthcare settings. The organization maintains a policy platform, files public comments on proposed regulations, and runs an action center that lets ordinary members contact lawmakers on these issues. For people who have felt dismissed, that grassroots channel is one of the more valuable things the coalition offers.

The third stream is peer support and connection. The OAC runs an online community where members share experiences, and it hosts events that bring people together in person. The best known of these is the Your Weight Matters Convention, an annual gathering built around education sessions, expert speakers, and the simple value of meeting others on a similar path. There is also a Find a Provider directory on the OAC site that points people toward clinicians experienced in obesity care.

It helps to be clear about what the OAC is not. It is not a diet company, and it does not sell a weight-loss program. It does accept corporate sponsorship and partnerships, which it discloses, and it publishes annual reports and IRS Form 990 filings so that anyone can see how it is funded and governed. That transparency is part of why a curated business directory can list the coalition with confidence. The organization stakes its credibility on evidence-based information and on openness about its finances.

Why does an advocacy group belong in a directory of weight and obesity resources at all, next to government agencies and scientific societies? Because the patient perspective fills a real gap. Research bodies produce the science and clinicians apply it, but neither is built to help a person handle insurance denials, push back on workplace bias, or simply feel less alone with a stigmatized condition. The OAC works on exactly those problems. A visitor who arrives through this business directory and follows the link will find tools aimed at the lived experience of obesity rather than the laboratory study of it.

The organization frames obesity as a disease rather than a personal failing, a position that aligns with major medical bodies and that shapes everything it publishes. This stance matters for tone. The material avoids blame, treats treatment as legitimate medicine, and respects the dignity of the people it serves. For someone who has bounced between commercial programs that promised quick results, that change in framing can be the most useful thing the OAC provides.

Practical contact details are straightforward. The headquarters is at 4511 North Himes Avenue, Suite 250, in Tampa, Florida, ZIP 33614. The toll-free line is (800) 717-3117, and a direct local number, 813-872-7835, is also published. The website carries a contact form for inquiries, along with the full set of educational resources, the magazine archive, the provider directory, and the advocacy action center. Most of what a member needs is reachable online at no charge.

For anyone assembling a trustworthy business directory of obesity and weight-management organizations, the Obesity Action Coalition rounds out the picture. It represents the voice of patients, it is transparent about its funding, and it concentrates on access, fairness, and support rather than on selling a result. That focus, paired with a membership in the tens of thousands, makes it a reasonable first stop for a person who wants help understanding their options and standing up for their own care.
