I saw a TV program recently which followed a group of people in the assessment process for stomach stapling. The surgeon who performed the operations was featured eating a tin of tuna - which he has every day for lunch - and he said he never eats anything "Beige". He went on to list Beige foods as bread (all bread), cerials, rice, crisps, potatoes, cake, biscuits. It seems he gets all his energy from the carbs in fruit and veg.
It struck me that there can't much danger in copying him as he's a highly qualified surgeon. Also, it seems a watered version of the Atkins diet. I haven't managed to stick to the No-Beige diet but it's made me think. I didn't have pasta with my meaty sauce and salad this evening...
