At the moment, the recommended eating program is a low fat, ad libitum diet in which only the fat intake is specified. This leaves some sense of control in the hands of the patients, there is less problem with hunger and it appears to be both acceptable and effective in the medium term. The weight loss with such a diet is 1.0-1.5 kg a month and a weight loss of 10-15 kg in a year is an excellent result. This low-fat eating plan appears to be a good diet for the maintenance or follow-up phase of treatment. The fat intake can be determined on an individual basis. My preference is for a daily 40 g limit for men and a daily 30 g limit for women.
