i agree with löwenherz about the fruit issue. during my two years on a mostly raw vegan/vegetarian diet i've eaten about 6-8 servings of fruit per day which is not much more than what many consider "healthy" and i'm sure it would have ruined my health if i hadn't switched to (raw) paleo earlier this year.
one thing i noticed was that i got a lot of moles but at the time had no idea they were a result of the sugar from fruits (the fructose content, most likely) - AGEs that are visible and which i hope will eventually fade or perhaps disappear altogether again.
during summer i've still eaten fruit, a serving of berries from my garden each day, but at the moment i don't consume any fruits, or anything sweet for that matter, and i don't feel that i need it.
nevertheless it seems that a limited amount of raw or fermented veggies is good for me. i eat about 300-400g sauerkraut every day and the occasional salad with lettuce, cucumber, 1-2 carrots, onion, feta cheese, flax oil and spices. no tomatoes or other nightshade plants, though, because of the lectins and other antinutrients.
i feel good on this diet but i don't know if i'm ever in ketosis. i don't really consume any carbs except the small amount that's left in the aforementioned veggies and perhaps in kefir but i'm probably eating too much protein for my own good (about 100-120g/day) and afaik 58% of all protein is metabolized into glucose, always, which would disrupt ketosis as surely as carbs, just a little later.
i have a request. could those of you who have found their ideal diet please describe it briefly and include their blood type? i'm type A and it's said that those with bloodtype A do best on a vegetarian diet but shouldn't consume dairy. well, that's almost vegan and that didn't work for me. i'm concerned about milk/kefir and would like to know if there are others with type A who do well with dairy in their diet or not at all. supposedly there are certain proteins in milk that are similar to bloodtype B and cause blood clotting in type A. don't know if there's any truth in this but i'm curious.
@löwenherz - do you know any sources in germany where i can buy grass-fed organ meats and glands? apart from liver i've had no luck so far.
