The Protein-Sparing Modified Fast (PSMF) is designed for rapid weight loss. The program is designed for individuals who are at least 100 pounds overweight, have a BMI of 40 or greater, or a have a BMI of 35 with more than one chronic disease or condition. The program incorporates medical, nutritional, and behavioral components. The goal of this diet is to reach an appropriate body weight as determined by your care provider and registered dietitian. 

How does it work?

Carbohydrate, protein, and fat are the nutrients in food that provide energy for proper functioning, maintenance, and repair of the body. In addition to these three nutrients, the human body requires water, vitamins, and minerals for good health.

While on the PSMF program, only lean meat, seafood, poultry, and a limited amount of low-carbohydrate vegetables are consumed (the amount of protein is determined by your healthcare team). Carbohydrates such as bread, crackers, fruit, sugar, soda, and desserts, as well as additional forms of fat, are not allowed on this program. The high protein intake is to prevent the body from using its own protein stores in muscles, tissues, and cells for energy. Thus the program is a "modified" fast.

Behavior modification

Throughout the program, the registered dietitian will introduce new behaviors to encourage healthy habits. In order to be successful, serious commitment is required to change undesirable eating habits, which will help you reach and maintain your desired weight. Your physician or dietitian will recommend an appointment with a psychologist to assist with behavior modification.

Group education

During your time on the PSMF, you will have the opportunity to attend group education. During these activities, you will learn about life-long maintenance through changing lifestyle habits, while participating in food preparation, shopping, and other important nutrition-related activities. You will also have opportunities to discover and adapt new exercise habits.
