The Optavia diet, often referred to as the Optimal Weight 5&1 plan, is a meal replacement program focused on portion control and balanced nutrition to assist individuals in their weight loss journey. The program combines packaged foods with homemade meals and personalized coaching to optimize results. But, the program comes as a kit costing well over $500 and loaded with processed foods.

Our research team decided to take a closer look. All evidence shows that reducing caloric intake and adding exercise is the best way to reach healthy weight goals.

Does Optimal Weight 5&1 offer anything different to justify that hefty price tag? We looked at the kit ingredients, studied the diet plan, read user feedback, and summarized our findings for you.

Optimal Weight 5&1 Plan can be purchased through their Official Site.

Overview

What is the Optimal Weight 5&1 Plan?

Also known as the Medifast 5&1 Plan, the Optimal Weight 5&1 Plan is a program that helps you reach your ideal weight and maintain the results for the long term.

With the Optimal Weight 5 and 1 Plan, you will need to purchase a kit, which consists of Optavia products such as snack bars, shakes, smoothies, cereals, soups, and other Optavia foods.

The 5&1 dietary framework offered by Optavia sets a daily caloric range of 800 to 1,000 calories. Participants are guided to consume six meticulously portioned meals throughout their day. Five of these meals are designated as Optavia “fuelings,” while the remaining meal, referred to as the “Lean & Green” option, can be either crafted at home or sourced externally.

While many participants see value in enrolling in the official Optavia program to access its comprehensive benefits and support, the diet’s design also allows for considerable autonomy and adaptability. This means individuals can comfortably navigate the diet independently, highlighting the program’s versatility and user-centric approach.

• Nutrients–Some research suggests knowing portion sizes isn’t enough. The study shows tools aimed at helping the user learn portion sizes are effective.

Ingredients

Optimal Weight 5&1 Fuelings – Are the Ingredients Effective for Weight Loss?

Protein

Commonly found in meats, dairy products, eggs, soybeans, nuts, beans, seeds, and legumes, this macronutrient is made up of amino acids. It helps reduce appetite, repair the body, and build lean muscle tissue.

The American Journal of Clinical Nutrition notes that protein plays an important part in weight management. Additionally, the journal Obesity Factsstudied the connection between protein and weight loss, concluding “participants with more adherence rate in the HPD [high-potein diet] group lost significantly more weight.”

Fiber

This indigestible carbohydrate is also called roughage in produce, whole grains, nuts, beans, and seeds. It moves through the digestive tract to help with regularity and gut health. Based on research presented in the Journal of Nutrition, “dietary fiber intake, independently of macronutrient and caloric intake, promotes weight loss and dietary adherence in adults with overweight or obesity consuming a calorie-restricted diet.”

Essential Vitamins and Minerals

Found in a variety of foods, these nutrients are crucial for healthy body function. According to theNational Institutes of Health – Office of Dietary Supplements, “foods in nutrient-dense forms contain essential vitamins and minerals and also dietary fiber and other naturally occurring substances that may have positive health effects.”

However, excessive vitamin intake is also associated with a higher weight, according to research published inWoD.

Probiotics

Also called good bacteria, these are live microorganisms that help promote gut health, which aids with regularity and the prevention of problems like diarrhea and constipation. According to the journalNutrients, “probiotics, which are generally considered safe for human health, have shown some promise.”

Monk Fruit Extract

A natural sweetener used in foods and supplements, often to reduce calories. It’s more than 100 times sweeter than traditional cane sugar. Research available in theNutrition Journalconcluded, “this scoping review identifies the needs for future research to address the numerous evidence gaps related to health effects of NNSs [non-nutritive sweeteners] use.”

Side Effects

Optavia Side Effects: The Pain Behind the Progress
