Nicola,
I followed the links you provided and believe that most of it is just a sales pitch. I’m also not so sure that there is any significant difference between the fats he recommends and what he calls ‘derivatives’. By Peskin’s definition almost everything we eat is torn down and turned into derivatives by our digestion process which our bodies then use as building blocks for cells and as fuel. He may well be correct, but if these special fats are not available in the proper proportions in my everyday food, then there is something fishy going on (pun intended). Since his proprietary magic blend contains flax seed and coconut oils, I tend to think it’s mostly nonsense. These would not have been available to paleo man.
IIRC all those on ketogenic diets eat cooked meat, so their finding that they cause kidney stones is not relevant to you.
A very different diet, too different to be useful. IMHO
Supplementation with potassium citrate is revealing, in that on a raw diet we need no such supplements.
Interesting that you should come to this conclusion since I've been eating raw meat for over 4 years now and developed kidney stones. I agree that we shouldn't need supplements to lead a healthy life, however, I don't assume that my current ZC dietary protocol is in any way the best approach, it is just the approach I'm following at the moment. My current thinking is that raw VLC with a few carbs (30g-50g/day) coming from a bit of green plant material and/or tart or non sweet fruits is probably a sounder overall approach.
There's nothing wrong with ketosis. Ketonemia is good - prolonged ketonuria is bad.
How would you propose to know that you are in ketonemia unless ketonuria is present at some level for you to measure? Any peer reviewed studies you can point to that support your statement?
I have my doubts whether kidneys stones can be prevented on raw meat and fat/ZC diet just by adding a couple teaspoons of honey a day.
I don't think I've ever suggested this. In fact, I believe that honey of any type is no better or worse than other refined sugars. Just because bees did the refining doesn't make it any more fit for human consumption. My carb source of choice would be wild tart fruits like berries, or nonsweet fruits like tomatoes and cucumbers, with the occasional small amount of green plant material thrown in for color.
If you've read anything at all about what I believe is the main contributor to kidney stone formation, then you should know it is reduced fluid intake causing urine with a very high specific gravity which is conducive to allowing minerals to precipitate out and form stones. Like growing sugar or salt crystals in a super saturated solution. Low fluid intake seems to be present in almost all the cases I've been able to research.
