Type of Diet:
Optifast liquid shakes and supplements, some whole foods
This program is designed for obese patients (BMI over 30) and is available through doctors who provide Optifast services.
Can you keep it off on this type of diet?
Optifast has published results in 600 patients who have sustained weight loss of 5-10% of their body weight for up to five years. Since average weight loss is 52 pounds, this means a lot of the weight is re-gained, but some of the weight stays off.
Positives: This low calorie diet is supervised by physicians, blood work is done regularly and has a counseling program that involves professional help from registered dietitians.
Drawbacks: This diet is a low calorie formula diet and is not meant for people who are not morbidly obese.
