OPTIFAST Program is a medical weight loss program that closely monitor and assesses progress towards a better heath and emotional well-being. The advantage of the Program is that you are provided with a high-quality, calorie-controlled, nutritional plan that transitions to self-prepared every day meals while being supported by our multidisciplinary team. Unlike other meal replacement, the OPTIFAST program treats you as a whole person and not just your weight. Unlike fad diets, the OPTIFAST program has been proven effective in more than 80 clinical studies. More than 1 million people have participated in the program since 1974. To learn more about the positive results yielded by clinical studies on comprehensive weight management programs, visit the OPTIFAST website. The OPTIFAST program has been designed for people who have a body mass index (BMI)that is greater than 30 kg/m2. The program utilizes medical, nutrition and behavioral elements to achieve lasting weight loss.
