Intense Market Competition: The weight management and health & wellness industry is highly competitive, with numerous players offering alternative solutions, potentially impacting Medifast's market share and pricing power.

Regulatory and Legal Scrutiny: Medifast faces ongoing risks related to regulatory compliance (e.g., FTC, FDA) regarding product claims, marketing practices, and its direct-selling model, potentially leading to fines or operational restrictions.

Dependence on Coach Network: The company's sales model heavily relies on its network of independent coaches; challenges in recruiting, retaining, or motivating these coaches could severely impact sales and growth.
