OPTAVIA Fuelings

On our Optimal Weight 5 & 1 Plan® your body enters a gentle but efficient fat burning state. Choose from convenient, nutritionally interchangeable, scientifically-designed Fuelings. Each Fueling contains high-quality protein, which helps retain lean muscle mass. In addition to Fuelings each day, you’ll learn another healthy habit: how to make a Lean & Green meal for you and your family. When you know what optimal nutrition looks like, healthy eating becomes second nature.

Whether your goal is to achieve a healthy weight or to sustain your optimal weight and healthy lifestyle, our plans have got you covered. Work with your OPTAVIA Coach to choose the right path.

Your Journey to Optimal Health starts here.

We recommend that you consult a doctor prior to starting any weight loss program. Do not participate in any OPTAVIA Programs if you have gout, are pregnant, breastfeeding or under the age of 18. If you have a serious acute or chronic illness (e.g., heart attack, diabetes, cancer, liver disease, kidney disease, anorexia, bulimia, etc.), do not participate in any OPTAVIA programs until your doctor says you have recovered or stabilized. The Optimal Weight 5 & 1 Plan® is NOT appropriate for sedentary older adults (65 years and older), some people with diabetes, and those who exercise more than 45 minutes per day. For special medical or dietary needs, including food allergies, refer to our Program information online and talk to your OPTAVIA Coach.

You should consult a doctor before starting any weight loss program, change in eating habits, diet, exercise, or supplementation program. Talk to a doctor about the medications you are using, especially warfarin, lithium, diuretic medications or medications for diabetes, high blood pressure, or thyroid conditions before beginning any weight loss program.

NOTE: Rapid weight loss may cause gallstones or gallbladder disease for those at high risk. While adjusting to intake of a lower-calorie level and diet changes, some people may experience gastrointestinal disturbances (such as abdominal pain, bloating, gas, constipation, diarrhea, nausea or stomach ache), dizziness or lightheadedness, headache, hunger, fatigue, or muscle cramps; consult a doctor provider for further guidance on these or any other health concerns.

Do not consume an OPTAVIA product if you are allergic to any ingredient in that product.

We recommend 2 liters of water each day. Talk to a doctor prior to changing the amount of water you drink as it can affect certain health conditions and medications.

For the avoidance of doubt, the OPTAVIA programs and products are not labelled, advertised or promoted for any specific medicinal purpose, i.e. treatment or prevention, implied or otherwise, of any disease or disorder, including its related conditions.

The OPTAVIA programs, products and any of its materials and/or information do not in any way constitute medical advice or substitute for medical treatment. As the human body reacts differently for different people, we do not warrant the accuracy of the information or guarantee the claims, benefits or safety of the OPTAVIA programs and products.
