                                Studies show that medically supervised very low-calorie diets, like Optifast, can result in significant initial weight loss, with some patients losing over 50 pounds in 18-24 weeks. Knowing how long you should stay on Optifast is crucial for safety and success, as the program is structured into distinct, clinically-backed phases to ensure healthy weight management.
