What is Optifast?

The system uses a meal replacement strategy, which incorporates extensive patient education and assistance, for transitions to self-prepared regular meals. Optifast usually lasts 18-26 weeks and combines lifestyle education and medical monitoring.

It claims to be suitable for adults as well as adolescents with a 30 or higher body mass index (BMI). This is a healthcare-controlled system intended to help reduce weight and overall health. The program is developed and recommended for patients of most ages and who expect to seek weight loss services as part of a comprehensive therapy scheme.

Optifast is a Nestle Health Sciences brand that offers weight loss programs, whether obese or overweight, for people with a high BMI (30 or higher). The Optifast weight loss program includes the use of Optifast shakes and food replacement items like soups.

Although each clinic is slightly different, a weight management team typically includes a doctor who regulates health conditions daily, a nutritionist, and a behaviorist who leads weekly sessions on various lifestyle issues. They work with you to make a safe, healthy, and active living transition.

The Main Levels of the Optifast Diet Program

Optifast program consists of three stages, typically lasting 26-52 weeks:

Active Weight Loss Phase: Complete food replacement for 12 to 16 weeks

Patients start with monitoring and counseling meetings with their medical provider. They also start to eat a diet of nutritionally complete Optifast full meal replacement goods.

Transition Phase: 4 to 6 weeks transitioning to a healthy balanced diet

Increasingly, patients move back to self-conscious foods during classroom sessions to help change their food approach and adjust their long-term habits.

Pros and Cons of Optifast

Some questions have emerged concerning Optifast programs and products. However, the use of Optifast dietetic plans has several significant advantages and disadvantages such as:


  •  Optifast diet allows overweight and obese people to quickly and firmly reduce their weight.
  • Optifast products contain healthy ingredients that can make you slimmer and more robust. They work well for your mental health, which is essential to a healthy body.
  • This weight loss program encourages people to take better and more conscious lifestyle choices and teach them healthy eating habits.


  • Doctors and nutritionists monitor the eating habits. That indicates it is costly. Also, the overall sum can reach about $3,000. Several people are not able to afford this program.
  • The weight loss plan is severe and challenging. Many people cannot finish without cheating and consuming prohibited sweets or other food.
  • Many customers complained about the taste of some of the Optifast products, affirming that they are not as good as the business claims.
  • Regarding side effects, many users complain of constipation and other minor issues.

How Does Optifast Work?

Optifast uses a non – conventional weight loss approach. Although it works wonders for some, for others, it is a difficult task. The Optifast diet reduces calories to some extent. Although this may induce weight loss, a deficient calorie diet can be difficult for some to adopt.

When a person is planning to start the program and chooses a clinic in the area, the diet remains incredibly intensive and requires a lot of medical appointments. This can also prevent success and lead people to stop halfway through. This program is not for everybody. All patients are always under medical supervision.

While Optifast is a perfect short term solution, you shouldn’t count on it for the rest of your life. By adopting this plan, you can get back on the right track, but then you have to choose your lifestyle. You should also consider the likely side effects that this diet may have.

Where to Buy Optifast?

You can purchase Optifast using the Official Site. Also, Optifast’s products are available in pharmacies and hospitals.

How to Use Optifast?

Do not use fewer than four Optifast shakes a day. This can lead to muscle loss and poor healing after surgery. Sometimes, you have to drink more than four in some cases, but four is the minimum. You should mix one package of cold water with a total of 300 ml of shake. If you like, you can add ice cubes. Shake well or blend in a mixer.

How Much Does Optifast Cost?

There is a premium of up to $3.000 dollars to complete the whole Optifast diet program. These costs cover a total of 26 weeks and include appointments to Optifast hospitals, assessments, counseling sessions, and nutritional therapy. As a customer, you should obtain professional guidance from doctors, specialists, and nutritionists, who can also supervise your entire progress. Furthermore, food replacements often differ in quality and cost.

An Optifast shake, for example, could cost from $21 to $80. Given that Optifast’s products are only required to eat or drink in the first stage, it can become expensive instantly. Optifast also requires extra costs such as a monthly rate, starting rate, and service fees.

Overall, the price depends on personal goals. But Optifast products are not considered budget-friendly.

What do Optifast Reviews Say?

The results of this nutrition plan are more than satisfying for most clients and patients. In a relatively short period, they lose a lot of weight. With a quick look on the internet, you can find several satisfied customers who are more than happy with the results.

Instead, most agree that even for a sophisticated and comprehensive diet system, this program is quite costly. It is not a walk in the park to spend over $3,000 for a nutrition plan.

Some reviewers also said that particular products like soups from Optifast have an uncomfortable taste.

Is It Worth a Try?

Optifast VLCD is designed to help assist medically at-risk patients who are required to lose weight to reduce their risk of weight-related disease. This is also good for anyone who needs to maintain a healthy weight once the program is completed.

Optifast serves a variety of alternatives for food in several flavors if you are concerned about having to stick to consuming the same weight loss shaker every day. Such drinks, soups, sweets, snacks, and bars are available in supermarkets or hospitals.

The Bottom Line

Overall, Optifast seems like a feasible weight loss program, offering sufficient meal replacement products, according to the company’s statements. It is pretty expensive, but it is also useful.
