Isn't it just as unhealthy to continue to eat high fat cr*p and binge on 100's of carbs a day?? All of this "hypothesis" on LCing in general does nothing to inspire people to live by a healthy way of life - there will always be "opinions" on why this or that should be wrong, why it does you no good etc.
Of course people should not depend on sugar substitutes - or unheathy diets full of franken foods...but researchers need to realise that not everyone is the same and people can make informed choices - look at all of us!!!! We're not all adicted to sugar substitute because we a sensible enough to realise that we need to eat a balanced diet - I think that if they need to warn people about this kind of thing then the people who it's aimed at are probably too thick to do anything about it and change.
