Tell me more about the Optifast meal replacements?
Clinical studies show that when people are given very few food choices, or even no food choices, it is easier to decrease the amount of calories they consume each day. By taking away the selection and preparation of foods, and reducing the vast array of available foods, people lose weight. This concept is called “stimuli narrowing.”  By using a portion-controlled meal replacement such as OPTIFAST, all your daily nutrition needs will be met. The benefits of this type of diet are in the reduced calories, complete nutrition, and perhaps most importantly, in the ability to stick with the diet because no food choices are made. OPTIFAST has been used for over 40 years.
Is this diet safe
The OPTIFAST Formula has all the nutrients that are required for good health. Our meal replacement diet is medically supervised to ensure safety. Our physician will provide extensive education and support on how to lose weight safely. Our group weight loss sessions focus on dietary, behavioral and exercise topics. Optifast has been in the market for over 40 years and proven to be very safe and effective.
Will I be hungry on this diet?
The feeling of hunger and the desire to eat are real concerns. Usually the hunger fades within a few days of starting the diet. The program staff will suggest various techniques to accomplish this goal.
What can I do if I’m invited out to eat while I’m on the program?
Dealing with social eating events is one of the topics that the staff in the OPTIFAST Program will help you work through. There are a number of options to consider and strategies that people have successfully used to help them enjoy these social events and still stick to the program.
When I’m done with the program, will I be able to keep the weight off?
Our program is not merely a “diet.” It is a way of life and our team of healthcare professionals will help you achieve that. Our program is based on scientific research as well as what works and what doesn’t work in the real world. If necessary, participants in our programs can continue to use limited amounts of OPTIFAST products on an ongoing basis – for convenience or to reduce the number of food choices. Remember, weight loss is a journey and we are here to support you throughout this journey!
I have chronic medical problems. Is this program for me?
Absolutely! Weight loss helps stabilize many chronic medical conditions including diabetes, hypertension and high cholesterol. The program is unique because it is medically supervised and therefore it is recommended for patients with or without medical problems.
How do the OPTIFAST products taste?
Most individuals find them pleasant and satisfying.  Some may prefer one flavor over others.  Remember that these products are designed to replace food entirely for a limited duration of time.
What is the cost of the program?
There are several programs and costs vary. Because this program is physician supervised, your health insurance plans should cover the physician visits. Please call us at 908.206.4676 to schedule an appointment with Dr K to discuss details.
