Medifast Inc (NYSE: MED) is a weight loss and metabolic health company that develops, manufactures, and sells portion-controlled meal replacement products and coaching-based wellness programs under the OPTAVIA brand.

As of the fiscal year ended December 31, 2025, the company filed its 10-K on February 17, 2026.
