I just read a few articles and studies that show that a 80-20 (approx) diet of fat/protein with minimal carbohydrates, is feasible as long as there are enough minerals (sodium,patassium) in the diet.
I have a couple of questions:
First, what would the very long term effects of such a diet be? As the Inuit people were the last present to survice on such diets, did they live longer? Did they approach old age better (eg less dementia or osteoporosis or other age-related maladies)?
Second, farming has been around for at least 4,000 years and it is safe to say that 80 fat / 20 protein diet would exist only in very remore areas of the planet with no vegetation to provide ready sources of carbohydrates. If this is the case, why even consider such diets?
Third, from a general food-intolerance point of view, would the carbohydrate rich diets be the source of intolerances? Battling with moderate food intolerance myself, I have visited forums where sufferers describe their symptoms, eg wheat, gluten, lactose, tomatoes! and so on, but I have not seen anyone yet complaining about "meat" intolerance, for example "I ate this stake and had to run for the toilet". Could there be a link that we (humans) are not really meant to inject the huge quantities of fruit and vegetables that we do?
