Some people need rapid weight loss under medical supervision. For example, a person who is very restricted due to hip or knee osteoarthritis can fall into a difficult cycle. They are restricted in movement due to pain, which limits their energy production and makes it difficult to lose weight.
People in this situation often wait for joint replacement surgery, which may improve health and quality of life, but may have too high a body mass index (BMI) to be considered. People in this situation can benefit from an 800-calorie diet if other diets do not result in the desired weight loss.
