Medifast® Enters a New Era: Introducing Trilivy™, a Science-Backed Metabolic Health System

The leading health and wellness company unveils an evolutionary transformation from weight loss to optimal metabolic health, powered by breakthrough science and human connection

Baltimore, MD - [July 17, 2026] - Medifast, Inc. (NYSE: MED) today announced the launch of Trilivy, a comprehensive metabolic health system uniquely designed to support healthy lifestyle change. The launch also introduces newly formulated meal replacements, including the Trilivy Reset Fueling line enhanced with MetaVantage Technology™, a platform of proprietary ingredient formulas intended to optimize metabolism by unlocking key metabolic pathways. The launch of Trilivy marks a major corporate transformation, and the beginning of a new era focused on optimal metabolic health.

The transition from OPTAVIA® to a new brand with the launch of Trilivy represents an evolution of the company's vision, expanding beyond traditional weight loss to address the broader metabolic health challenges impacting more than 90% of U.S. adults today.1

"Medifast is evolving with the health and wellness landscape, and we believe Trilivy represents an important step in leading the conversation and building mindshare around metabolic health," said Nick Johnson, CEO of Medifast. "Trilivy honors the strong foundation we've built while embracing a brand that reflects where we're headed: a modern metabolic health company built for today's world and tomorrow's opportunities. By uniting breakthrough science, individualized support, and sustainable habit creation, we have developed a system intended to help people transform their metabolic health, which has become one of the biggest health challenges people face today. Trilivy will put people back in control with the support they need most, giving our coaches and clients the opportunity to help build a better future for metabolic health."

At the center of the system is Metabolic Synchronization®, the company's breakthrough science that reverses metabolic dysfunction2 with a targeted reset of the body's metabolism through three key mechanisms:

•Burn: Targets visceral fat - the bad fat stored around organs and muscles - achieving a 14% reduction in visceral fat in just 16 weeks.2

•Preserve: Helps retain 98% of lean mass, supporting strength, energy, and mobility during weight loss.2

•Protect: Supports healthy muscle to help restore the body's natural ability to maintain an active metabolism, optimize energy use, and regulate body weight.

The system is structured across three phases:

•Phase 1: Reset. Reverse metabolic dysfunction2 and reset metabolism.

•Phase 2: Refine. Improve metabolic flexibility and refine body composition.

•Phase 3: Renew. Optimize metabolic health and support healthspan.

Accompanying the brand launch is the Trilivy Reset Fueling line enhanced with MetaVantage Technology, which further supports metabolic health by helping reduce waist circumference3 while also supporting normal fat metabolism and healthy insulin function.

The brand launch also reflects the powerful momentum behind the Trilivy community, strengthening the connection between the brand and its nationwide network of independent coaches, who remain central to the human connection and accountability that has, and continues to, differentiate us. Clinical research has shown individuals using the company's coach-supported program lost up to 10x more weight and 17x more fat than those trying to lose weight on their own.4
