Our Fuelings help make change easy. They remove the guesswork and offer a simple, nutrition-dense, delicious variety of choices to help you build new healthy habits.
All OPTAVIA Essential Fuelings and OPTAVIA Select Fuelings contain 24 Vitamins and Minerals; high-quality, complete protein; the patented probiotic GanedenBC30®; and no colors, flavors, or sweeteners from artificial sources. Best of all, each Fueling is nutritionally equivalent and portion-controlled,
so you can substitute any one for any other. Not in the mood for soup? Try a brownie instead!
Lean & Green Meals
Your Coach can help teach you another daily healthy habit: Lean & Green meals. A Lean & Green meal includes cooked lean protein plus three servings of non-starchy vegetables and up to two servings of healthy fats. That means your options are virtually unlimited, with a wide spectrum of vegetable and protein choices. Best of all, you can enjoy a Lean & Green meal any time of day — whatever works best for your schedule.

Optimal Weight 5 & 1 Plan®
Our most popular plan is the Optimal Weight 5 & 1 Plan®. It, along with our clinically proven plan, was designed by physicians, dietitians and scientists. It helps you feel full while learning the healthy habit of enjoying six smaller meals each day. That means that every 2 to 3 hours, you’ll get to enjoy delicious, nutritious food that fits your lifestyle.
The Optimal Weight 5 & 1 Plan® is uniquely flexible and simple, with dozens of delicious, convenient, nutritionally-interchangeable, scientifically-designed Fuelings. Of course, your Coach will help you customize and choose the perfect plan to meet your personal goals.
