Suggestions for light low carb after severe gastroenteritis

Any ideas gratefully received ...Eggs excepted as they caused the problem in the first place ... May be a while before I can look an egg in the face again even as an ingredient.

Surgery nurse (who said something along the line of "your blood sugars will be pretty low after nearly a week of no food") has suggested probiotic yoghurts - until I pointed out the amount of sugar in them, dried toast (after I said I had given up bread) and jacket potato (after I had explained that I had given up potatoes) and porridge (after I had explained that I have given up cereals) ...


Just managed a few teaspoons of cod followed by 1/3 banana yesterday with no repercussions.

Well enough to direct hubby in the cooking ... Thanks

Marmite sounds good ... Thanks
