Optifast is a weight loss program that tries to include all aspects of a healthy lifestyle, like diet supplements, meal replacements, medical clinics, and more. The plan promises weight loss and a decrease in waist circumference. However, ingredients like sucralose and canola oil haven’t been shown to do have any of those benefits.

The Optifast weight management system requires the use of Optifast shakes and meal replacement foods such as bars and soups. Their programs claim to be for those who are overweight, people of most ages, teens, and people who plan to undergo weight loss treatments.
The programs are also comprehensive, which means that doctors, psychologists, and other health professionals are involved in the weight reduction journey of each person enrolled in the Optifast system. An Optifast meal plan consists of a liquid diet including Optifast shakes.
Typically, you’ll follow the diet for at least four weeks. The timeframe makes it easy for almost anyone to follow. Weight loss from this eating plan results from eating a very low-calorie diet (VLCD). Optifast is a VLCD option for those seeking immediate help with their body weight.

Optifast offers several different products. However, the Optifast Method relies on meal replacement shakes more than other pre-packaged foods. Some Optifast ingredients include:
Milk Protein Concentrate
Soy Protein Isolate
Some concerns regarding the Optifast programs and products have surfaced from time to time. However, there are some key benefits to using Optifast diet plans including:
Easy prepared meals
Maintenance support for long-term results
Optifast diet plans are some of the only comprehensive diet plans that provide medical support, nutritional counseling, and meals. Other weight management systems may provide medical and nutritional counseling, but they won’t provide the actual food that the dieter needs to eat.
Optifast results occur when the dieter lost weight and improved overall health and wellness. The Optifast programs are primarily for health purposes and not just physical shape or numerical weight. A person who has gone through the program and has signs of improved health is considered a success.

However, the risks that may occur whenever a person starts a diet like this include:

The Optifast Diet
What is the Optifast Diet?
The Optifast Diet is boasted as “the serious solution for weight-loss” and claims to be suitable for both adults and teenagers with a body mass index (BMI) of 30 or greater. Basically, this is a medically supervised program that’s intended to help with weight reduction and overall health. It typically lasts for 26 weeks and may be partnered with a weight-loss surgical procedure. This program involves:
Meal Replacement Diet
Ongoing Personalized Support
Since Optifast diet plans aren’t the same for everyone, each person will have different directions that they need to follow. They’ll need to follow the guidelines established by their physicians and dietitians over the course of the main dieting phases.
Most dieters consume around five shakes per day and maybe even a few snacks, but the caloric allowance will depend on the weight and health of the user.
What is the Optifast Cost?
The cost of the entire Optifast diet program may run upwards of a few thousand dollars. The cost includes visits to Optifast clinics, applicable tests, therapy sessions, and nutritional counseling. Also, meal replacement products vary in cost as well.
For example, an Optifast shake can cost between $21 and $80. Considering the dieter is only allowed to eat or drink Optifast products during the first phase, this may get expensive fast. There are also additional costs associated with the Optifast. There are reports of a monthly fee, a starting fee, and service fees.
Moreover, the price varies depending on the goals of the person. However, some consider Optifast products not budget-friendly. You can contact the company directly for specifics relating to price.

Does Optifast Work?
Optifast uses a non-traditional approach to weight loss. While great for some; it’s a challenge for others. The Optifast diet restricts calories to a certain degree. While this may cause weight loss, some find it difficult to follow such a very low-calorie diet.
Assuming a person is ready to start the program and finds a clinic nearby, the diet is still very intensive and will require a lot of time off of work or school for medical appointments. This may also be a deterrent to success and may cause people to quit halfway through. Some of the ingredients used in Optifast products are also questionable.
But, they may not prevent the dieter from losing weight, which is the main purpose of the program. Perhaps the best way to get a better idea of whether Optifast works is to take a look at some Optifast user reviews.
The Optiwin Study
The OPTIWIN study is a 52-week open-label, randomized, controlled clinical trial that assessed the safety and efficacy of the Optifast weight-management program.
In the OPTIWIN study, the Optifast group was comprised of 135 participants who followed a total meal replacement plan for 16 weeks. The meals were made up of 40% carbohydrates, 40% protein, and 20% fat. Traditional foods were introduced gradually after 16 weeks.
The food-based group was comprised of 137 participants who followed a reduced energy diet that adhered to the Diabetes Prevention Program guidelines. Both groups exercised vigorously for 150-180 minutes each week. They also attended behavioral counseling sessions.
The Optifast group lost twice as much weight as the food-based group. The mean weight loss for the Optifast group was -12.4% compared to -6.0% for the food-based group. Optifast participants saw greater reductions in fat mass(30%-64% vs. 12%-42%) and waist circumference(p=0.011 vs. p=0.0011) as well.
