Nutrisystem is a direct-to-consumer subscription meal delivery service for weight loss, founded in 1972 by Harold Katz and headquartered in Fort Washington, Pennsylvania. The company pioneered prepackaged weight-loss meal subscriptions, transitioned from physical retail to a direct-to-consumer Internet and telephone model in 1999, and added mobile delivery beginning in 2010. Nutrisystem is now operated under the marketing umbrella "Wellina by Nutrisystem" — a multi-brand health and wellness marketplace covering Nutrisystem, Jenny Craig, High Protein, Menopause Support, Low Carb (GLP-1 friendly), and the Club Advantage à la carte membership. The legal operating entity is Nutrisystem, LLC, a subsidiary of Wellful, Inc. (the parent organization formed after Kainos Capital acquired Nutrisystem from Tivity Health in October 2020). Tivity Health no longer owns the brand. Wellful's portfolio also includes South Beach Diet (acquired by Nutrisystem in December 2015 for $15 million) and the Jenny Craig intellectual property (acquired by Wellful in fall 2023 after Jenny Craig's Chapter 7 bankruptcy and relaunched as an e-commerce meal-delivery brand). LinkedIn classifies the company under Wellness and Fitness Services with 501–1,000 employees. Stephen Mikulak was named President in 2021. Nutrisystem publishes no public developer APIs, OpenAPI specs, SDKs, or developer portal. Its only digital surface beyond the e-commerce sites is the consumer-facing Nutrisystem mobile app (iOS / Android) for food logging, weight tracking, journaling, and meal-plan adjustments — and the equivalent Jenny Craig app — neither of which advertise integrations with Apple Health, Google Fit, Fitbit, or any third-party platform. The github.com/nutrisystem GitHub organization exists but contains a single inactive CSS repository last updated in March 2015. The technology footprint is a closed consumer subscription stack with no public developer touchpoints.
