OPTIFAST is a program for losing weight that utilizes different types of meal replacement products as the heart of their diet plan. These various products are manufactured by the international food production giant, Nestlé. They include various formats of meal replacement such as:

  • Prepared drink shakes
  • High protein drinks
  • Soups
  • Powders
  • Mutrition bars
  • Vitamin and mineral supplements

According to Nestlé, OPTIFAST’s program only begins with the meal replacement products, but it also necessitates special medical monitoring in order to keep track of all of the progress being made and ensure that motivation remains high. 

What the Program Involves

The program by OPTIFAST involves a subscription which includes the medical testing that is needed by the plan. This testing occurs at the start of the program, which is a thorough examination, and includes the required lab tests that will ensure that the dieter is appropriate for the program and that risk factors and health status can be effectively identified.

The monitoring is also included in the program, making sure that a personalized activity plan is accurately created and is being followed properly for optimal progress.

OPTIFAST also offers discussion groups for their dieters so that they can talk about issues they are facing, struggles, and victories that they have had. There is also the chance to talk to a registered dietitian, physician, or lifestyle counselor for personal counseling, one-on-one.

Though there is an official OPTIFAST website, this is for informational purposes only. In order to register and take part in the program, dieters must make an appointment and attend an OPTIFAST clinic for a free no obligation consultation that takes about an hour. The site provides a convenient search tool to help you find the closest clinic to your location.

The price is also not available on the website for the entire program or for the various meal replacement products. The reason, according to the website, is that this program varies by city and by clinic and on the specific program that is right for an individual’s weight loss goals and medical situation. 


There are different benefits associated with taking part in the OPTIFAST program. Some of these include:

  • Detailed website – As previously mentioned, at the writing of this OPTIFAST review, there is an official informational website. The site including information about the program, an FAQ, a list of their products, etc. There is also information about the OPTIWIN Study, which is a year-long study designed for the purpose of evaluating the effectiveness of the program.
  • Medical monitoring is included – This is a medically-supervised weight loss program that closely monitors and assesses progress toward improved health and emotional wellbeing.
  • Straightforward program to follow – The program includes eating full meal replacement products, monitoring, counselling and educational classes. It is split up into three phases and each one is clearly laid out for the follower. 


There are disadvantages to the OPTIFAST program as well. Some of these include:

  • Cost – The fact that prices (even a pricing range) is not available for the program or the meal replacement products they sell, leaves the impression that this is a costly program, particularly as it has been designed for the long-term. The fact that you have to actually spend time to go to a clinic and talk to someone for an hour just to get a price is inconvenient to say the least.
  • Products can only be obtained from a clinic – If you want to purchase the food products, you can only do so at a clinic. The product can only be viewed online, which seems very behind the times in our digital shopping age.
  • Meals are repetitive – Many dieters find it difficult to have to adhere to a diet limited only to OPTIFAST products and find that the selection and variety become repetitive over a short time.
  • Lack of convenience – Having to make regular trips to the clinic for medical tests and monitoring, as well as to buy the meal replacement products can be quite time consuming.

Ultimately, if you are interested in tying the OPTIFAST program, remember that it is very important to speak with your healthcare provider about your plans to do so first. Simply because this program has been studied and those who partake in it are medically monitored, does not mean that you should not consult your personal healthcare provider. Discuss the OPTIFAST program with him or her to determine if this is something worth pursuing for your specific health and lifestyle.

I just couldn’t come anywhere near sticking to this plan. It felt so fake. It was as though I was waiting for a real meal to show up at any minute and then it never arrived. I didn’t find it hard to get the products because a lot of them were all available at a store near my house, and the clinic was on my way home from work but there wasn’t enough variety and it just didn’t feel right.

It’s even worse when you don’t have a clinic nearby.

Optifast worked for me. Why? Because it took food out of the equation. I am an emotional eater. I eat, when happy, sad, depressed, whatever. Optifast gave me a break from food, and three shakes a day actually filled me up. The only thing is, is that social gatherings are hard on this diet so I would recommend to avoid them in the beginning while you are getting used to it. After that, it does get easier. Dieting is hard work. There were so many times when I was bored that I wanted to eat. You don’t realize how much you turn to food when you don’t actually need it.

I’m struggling with that same problem of not knowing exactly what to do in social situations, such as when you want to go out to eat with friends, or when you are visiting friends or family for meals. I plan to just eat normally on Thanksgiving because I’m not going to snub my family’s generosity, but it really is challenging when you want to spend time with the people you’re close to, because food is such a central part of that. Did you come up with any tricks that you can share? I’m currently at a loss. It’s such a great program other than that!

I absolutely loved optifast. It just did everything that I needed it to do. It was fast, simple, easy, and convenient. I lost weight consistently, but not too fast or slow.

I’m having a hard time getting my hands on Optifast products. There isn’t a clinic near me. Is there anywhere that they can be ordered online, instead? I’ve never seen a diet that makes you work this hard just to get started, haha

If you don’t live near a clinic you likely won’t find it to be worth your while because it will be too hard to get your products and keep up with them.

Out of curiosity, I did a bit of searching on the web and a lot of people have found that this stops them from getting full benefit from the program. Even when they live not too far from a clinic, actually having to go there is a pain for them.

I found that there are some non-official sites that sell some of the products online, but that’s also limiting because the selection isn’t the same. Plus then you have to worry about how old it might be etc. If you’re out of the area, you might also be out of luck. Sorry to tell you!
