I went on Optifast for six weeks prior to surgery - four weeks at doctors request.. but I don't mind Optifast... I lost 11Kgs before surgery and surgeon was very pleased as the preparation had been so good. On some weekends I had 1 evening meal of lean meat and salad - no carbohydrates. Hope that helps.
