Optimal Weight 5&1 Plan promises a “gentle but efficient fat-burning state while maintaining retaining lean muscle mass.” The plan claims to help you reach and maintain your weight through a combination of supplements, meal alternatives, and coaching. But, the program comes as a kit costing well over $400 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.

According to the journal Obesity Science and Practice, “Evidence‐based commercial programs can be an important tool to help adults with overweight and obesity lose clinically relevant amounts of weight.”
How to Get Started With Optimal Weight 5&1 Plan

Other Optimal Health Programs

Unlike the Optimal Weight 5 & 1 Plan, this program involves eating three balanced meals a day and three Optimal Health fuelings to sustain your healthy weight. But portion sizes are still relevant, and you need to eat every 2-3 hours to stay on track. A final option is the Optavia 4&2&1 Plan. On this plan, you eat four Optavia Fuelings meals, two green and lean meals you prepare, and a snack.
Optavia Food – Is The Optimal Weight 5 & 1 Plan Healthy?
There are dozens of Optavia Fuelings to choose from on the 5&1 Plan. This includes supplements, snacks, shakes, teas, smoothies, bars, desserts, pasta, and even breakfast foods.
While these Optavia products are available individually on the official website, you can also find them in the kits. You should expect to eat many bars and shakes on this diet plan, which is processed foods.
Optimal Weight 5&1 Fuelings – Are the Ingredients Effective for Weight Loss?
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 reports, “Potential beneficial outcomes associated with protein ingestion include the following: 1) increased satiety—protein generally increases satiety to a greater extent than carbohydrate or fat and may facilitate a reduction in energy consumption under ad libitum dietary conditions; 2) increased thermogenesis—higher-protein diets are associated with increased thermogenesis, which also influences satiety and augments energy expenditure (in the longer term, increased thermogenesis contributes to the relatively low-energy efficiency of protein); and 3) maintenance or accretion of fat-free mass—in some individuals, a moderately higher protein diet may provide a stimulatory effect on muscle protein anabolism, favoring the retention of lean muscle mass while improving metabolic profile.”
Additionally, the journal Obesity Facts studied the connection between protein and weight loss, concluding “participants with more adherence rate in the HPD [high-potein diet] group lost significantly more weight.”
Also called roughage, this indigestible carbohydrate is found 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 the National 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.”
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 journal Nutrients, “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 the Nutrition Journal concluded, “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.”
Optavia Side Effects
As with most diet foods and supplements, you may notice some side effects with Optavia prepackages fuelings. This is likely due to certain ingredients. Some of the reported side effects are as follows:
- Loose stools
- Upset stomach
Medifast customers mentioned these unpleasant effects states Consumer Affairs.

Optimal Weight 5&1 Weight Loss Results
According to the official website, the average weight loss on the Optimal Weight 5&1 Plan is 20 pounds, which occurs in an average of 12 weeks. But weight loss results will vary from person to person, depending on your effort and lifestyle.
“I am now down 44 pounds on 1/29/2020. What a blessing this program has been for me. Even in Disney World this past week, I was successful in eating only on plan and didn’t waiver. I lost five pounds while on that vacation. We were gone three weeks. I get on the scale with anticipation, almost daily, because the scale goes down enough to actually see results. I had a bit of a slowdown during and after Christmas, but I still ate on plan. The worst thing I did on Christmas day was maybe overeat on shrimp cocktail and vegetables with ranch dressing.”
“The best!!! I’m loving this program. Nothing else has helped me lose weight like this before and the best part is, I’m not hungry!! These bars are delish, remind me of the thin mint Girl Scout ones!!”
“The Optavia Mint Chip bars are one of my favorite flavors from the 5&1 plan. I am a fan of mint anyway and they remind me of a Thin Mint girl Scout cookie. I will be ordering them with each shipment. Some of the Optavia products have a protein powder smell and this one does not. A must have if you love mint chocolate.”
The Bottom Line on Optimal Weight 5&1 Plan
Controlling your daily caloric intake and food portion sizes with the Optimal Weight 5&1 Plan may indeed help you drop some pounds. After all, it has been shown that reducing your calories aids with weight loss.
This Optimal 5&1 Plan indeed offers a lot of food options, and you do receive coaching to help you reach your goals. But there are a few concerns we have with this Take Shape for Life program:
- The cost is north of $400 a month.
- Some customers have made negative comments about the taste of Optavia foods.
- Some users experience bloating gas and loose stool.
