GrannyIsland be careful about keeping calories low because you need the high-fat food to make the regime work. It seems counter-intuitive, I know, but you need to eat olive oil and things like full-fat yoghurt, cream, butter and cheese in moderation. The theory (as I understand it) is that if you eat fat and carbs the body burns the carbs and leaves the fat. If there are few carbs to burn then it burns the fat slowly and you don't feel hungry.
It isn't a no carb diet because you eat vegetables especially those grown above ground. Fruit juice is a no-no and only small amount of fruit allowed; berries are best. Full-fat yoghurt, berries and seeds are a favourite breakfast and eggs are good.
My mayo recipe is the classic one. One egg yolk to 1/4 pint olive oil, drip at a time beating as you go, once you have a good liaison add teaspoon of vinegar or lemon juice and drip the second half in more quickly.
