In fact, she credits Precision Nutrition with saving her health — maybe even her life.
Sarah finds strength, inside and out
After emerging from the six-month Lean Eating in 2010 as a finalist, Sarah suffered some life events that left her reeling. The result?

Cheryl defeats her inner skeptic
At 49, Cheryl Eckler wanted to lose weight. She needed to lose weight. But, as a life-long learner she was too smart to be taken in by diet scams. And she wouldn’t consider weight loss programs.

Through the program, she lost 70 pounds. She even went on to win our $25,000 grand prize.

Peter’s road warrior experience
Peter Blynn was an expert on getting into shape. Over his lifetime, he must have started at least 25 different workout programs. Trouble was, he’d also stopped.
