NAICS 812191 – Diet and Weight Reducing Centers covers non-medical, outpatient health and wellness services focused on behavioral nutrition, physical activity coaching, and structured weight management programs. These centers typically deliver evidence-based interventions such as dietary counseling, metabolic monitoring, lifestyle modification training, and behavioral therapy aimed at promoting sustainable weight loss and improved metabolic health. While primarily a private-sector service category, this NAICS code may intersect with federal health initiatives when contracted to support employee wellness programs, veteran reintegration support, or preventive care services within military and civilian health systems. The services are distinct from clinical medical treatment and do not include pharmaceutical or surgical interventions, positioning them within the growing preventive health and population health management segment of federal contracting. No contractor data is available for this NAICS code, indicating limited or no recorded federal procurement activity from identifiable prime contractors or subcontractors. The competitive landscape appears fragmented, with potential participation from small businesses, community health organizations, and wellness startups, though none have yet emerged as dominant federal vendors. No agency data is available, suggesting that government demand for these services is either minimal, sporadic, or embedded within broader health and human services contracts rather than being procured as standalone line items. Potential demand may arise from the Department of Defense’s Military Health System, the Department of Veterans Affairs, or the Department of Health and Human Services in connection with workforce wellness or chronic disease prevention initiatives. The market context reflects low opportunity density in federal procurement, with limited visibility into structured contracting pathways. Contractors seeking entry should consider aligning services with existing preventive health programs, leveraging certifications in behavioral health or corporate wellness, and targeting pilot programs within federal employee assistance or occupational health divisions.
Small Business Size Standard
The SBA threshold that decides who can bid NAICS 812191 work as a small business.
The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.
13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
