I know I am being a bit dim- but can anyone explain, in simple terms for a simpleton- why HIGH FAT is good: I totally get the no carb and no sugar- but why does it have to be compensated by high fat in extreme amounts? Surely one can cut carbs and sugar, and have some sensible fat, but surely loads and loads of eggs, butter, full-fat cream, etc (and have always believed that a little butter or olive oil is better than substitutes- I know too many women with osteoporosis who have cute ALL fats from their diet forever...) - eg, in an extreme manner, the more the better... can't be good for you? Don't get it (sorry).
