Weight loss and health benefits
The OPTIFAST® Program is a medically-supervised weight loss program that closely monitors and assesses progress towards better health and emotional well-being. The program is designed to help overweight and obese patients lose weight safely without surgical intervention. It is a total meal replacement program that includes 100% of the recommended daily value for at least 24 vitamins and minerals, ensuring you are getting all the micronutrients you need. The products are designed to be low-calorie, high-protein, and pre-portioned.
The program consists of three key phases. During the first phase, the Active Weight Loss phase, participants consume OPTIFAST® products exclusively and receive monthly medical monitoring. This phase typically lasts for 16 weeks, although there are also 12- and 24-week program options available. During this time, participants are encouraged to avoid exercising regularly at a high intensity and frequency as their bodies adjust to the new diet.
In the second, or Transition Phase, solid foods are gradually reintroduced into the diet, while patients attend classes to help change the way they think about and approach food and eating. This phase typically begins around week 10 for the 12-week program option and week 18 for the 24-week option, with expert guidance provided to help navigate the transition.
The third phase is the Long-Term Weight Management Phase, which is ongoing and can include a partial OPTIFAST® meal replacement and partial regular food, along with ongoing support. This phase focuses on helping individuals address and modify behaviours to encourage long-term weight management through nutrition, exercise, and lifestyle changes. It is important to note that weight regain after the program is not unusual, and persistent adherence to healthy habits is key.

Optifast's program phases
The Optifast program is a medically-supervised weight loss program that closely monitors and assesses progress towards better health and emotional well-being. It is designed for people with a Body Mass Index (BMI) greater than 30, or for people with weight-related medical conditions who have a BMI greater than 28. The program is flexible and allows users to choose from 3 to 4 levels, tailoring their weight loss plan to their goals.
The Optifast plan consists of three phases: the Intensive Phase, the Transition Phase, and the Stabilization Phase. The Intensive Phase is the first phase of the Optifast plan and is generally followed for 12 to 16 weeks. During this phase, patients restrict their carbohydrate and total energy intake, typically consuming 800-1280 calories per day. Patients who actively participated in a 26-week medically-monitored program typically lost about 13.5kg. If, after 12 weeks, a patient still has significant weight to lose, they can follow the Transition Phase for a minimum of 2 weeks before repeating the Intensive Phase.
During the Transition Phase, patients replace one Optifast meal with a regular, healthy meal. During this phase, patients generally continue to lose weight but at a slower rate. Some people may experience a slight weight gain, typically of about 2 pounds, when carbohydrates are added back into the diet.
The final phase of the Optifast program is the Stabilization Phase. During this phase, patients continue to receive ongoing monitoring and education to ensure long-term weight management. Eating vegetables and fruit during this phase helps with the transition to a balanced, calorie-controlled diet. Patients who continue to use weight maintenance programs after completing Optifast have a greater chance of keeping the weight off long-term.

Optifast's safety and effectiveness

The program is designed to be safe and effective, providing medical, nutritional, and behavioural support to help individuals lose weight and improve their health. It is a comprehensive program that includes a partial or total meal replacement plan with shakes, soups, and bars delivering between 160 and 230 kcal per serving, providing 800 to 1000 calories per day. The program also includes lifestyle education, counselling, and support to help individuals change their relationship with food and make long-term lifestyle changes.
The Optifast program is designed to be safe for individuals with a body mass index (BMI) of 30 or above, or those with a BMI of 27 to 30 who have weight-related conditions such as prediabetes, diabetes, high blood pressure, high cholesterol, sleep apnea, joint pain, or liver disease. The program is also suitable for individuals who want support in overcoming emotional barriers to weight loss. It is important to note that Optifast is a medically supervised program, and participants are closely monitored by medical professionals to ensure their safety and address any health concerns.
The effectiveness of the Optifast program has been demonstrated in various studies, including the OPTIWIN Study, which compared the Optifast program to a food-based (FB) dietary plan for weight loss. The study found that the Optifast program was effective in helping participants lose weight, with some individuals losing more than 12% of their body weight at 6 months. Additionally, participants in the Optifast program experienced lower blood pressure, total cholesterol, and blood sugar levels. The program's partial or total meal replacement plan, in conjunction with comprehensive patient education and support, has been key to its effectiveness.
However, it is important to note that some individuals may struggle to follow the program due to the rapid and drastic lifestyle changes it entails. Additionally, there have been concerns about long-term weight loss maintenance after completing the program. While the program provides ongoing support and encourages periodic or continuous involvement in a weight management program, some individuals may find it challenging to maintain healthy habits and are prone to relapsing. Overall, the Optifast program has been shown to be safe and effective for individuals seeking a comprehensive, medically supervised weight loss program, but long-term commitment and persistence are crucial for sustained results.
