Question (I'm really trying to wrap my head around the ketogenic diet) :
IS there a difference in which the body would function in a ketogenic state (including how it would use fat for fuel and how it would feel) if one were to:
a) Eating 80% fat...under 20g carbs of just a few greens..mod protein. say .75 per lb of lean body mass... and achieve ketosis..
b) Eating saying 50-60% fat...same protein, but eating around 40-50g carbs only from greens, but Supplementing with MCT, and Lysine/Leucine...
Any experience with both and how they differ?
I tried A) recently...but am finding B) might work better for me...but I'm not feeling the same effects..
Hope this makes sense! Thoughts...?

I've done something close to a) before. The big worry with b) is what the leucine is doing to you. Insulin will increase in response to it, as you likely know because bodybuilders appear to be supplementing about 20g of it in order to saturate a pro-growth pathway. So, this in turn makes it a bit hard for you to access fat stores, at least until the insulin level subside, which is why you aren't feeling the same effects. This comes down to what your goals are. It is usually best to lose weight, then try to gain muscle- and if you decide to use pro-growth agents, use them for a short amount of time. The season in which we would have likely received the most incentive to grow would likely have been in summer.

This is off the cuff, but I don't believe there is a one-size-fits-all number for fat:protein:carbohydrate ratios or specific quantities of which fatty acids ... even based on body mass index etc. I think you just have to discover this through your own (careful) experimentation *. Based on your genes you may be prone to cellular insulin resistance and/or inefficient at storing glycogen etc., so your requirements for nutritional ketosis might be higher than others'. Your metabolism of certain FAs may also be impaired, etc.
(*) I say careful because radical dietary changes can sometimes be dangerous (even if the end result is not). Really do find a professional doctor or nutritionist whose theories you can trust. They should be able to help you achieve nutritional ketosis without any bad things happening . While usually sudden ketosis can be safe (I believe) it does perhaps have a drug-like effect  and this can be unexpectedly intense (there are some anecdotes of the onset of ketosis triggering pretty intense manic episodes in bipolar individuals, for example) and or really, really dangerous given actual drug interactions (at least with valproic acid) in certain individuals . To me, this is not so much a specious warning, but one anyone should consider; bipolar could be very common and I venture to guess many people just have never been diagnosed!
[Note: I don't mean to fear-monger at all; I'm personally a fan of a nutritional ketosis. But really do your homework and get professional advice if you want to radically alter your diet in short time.]
