Medifast is a health and wellness company that sells science-backed nutrition products and lifestyle coaching for weight loss and metabolic health through an independent coach network. The company operates a direct-to-consumer model where coaches—many of whom were clients first—provide personalized guidance and market products to individuals seeking to improve their metabolic health, with Medifast handling product manufacturing and fulfillment while coaches earn commissions on client sales and recruitment. Revenue comes from clients purchasing tailored product kits on coach recommendation, with the company differentiating itself through proprietary nutrition plans, clinically tested products, peer-reviewed research, and a model that positions coaching and community support as essential to lifestyle change, while competing with traditional diet companies, pharmaceutical solutions like GLP-1 medications, and digital health platforms.
