WHAT IS LEAN SNACK? Not just another protein powder, Lean Snack is a high quality "functional food." It's a 100% natural complete meal, an appetite suppressant, a fat burner, and a health tonic, all in one. It's a premium drink mix unlike any other. As seasoned fitness consultants, we've witnessed over and over the need for a healthy between-meal alternative to typical fast food and designed our own solution. Lean Snack is a lifestyle "tool" that will help people to discipline their eating habits.
