Low Carber
For a couple of days now i've been reading various sites about low carb diets and something i've come across which seems to be generally accepted is that our bodies need glucose to function properly. When in ketosis, ketones replace SOME of the glucose we need which is apparently about 200g per day and gets this down to 130g per day.
On a low carb diet, according to these sites, this glucose comes from protein which is converted to glucose in order to fuel certain cells. The conversion rate is about 1g of protein to 0.7-0.8g of glucose so to use an average of 0.75g we would need 173g of protein a day just to function properly before we even considered needing protein for growth, repair etc etc.
I was under the impression from Atkins that there were 'two parallel fuel systems' and ketosis took care of everything. Surely none of us can be hitting about 210g of protein per day?
I had begun an ultra high fat version of Atkins today where my macro breakdown was: F 166g P 85g C 12g. This feels a bit wrong now.
I had a theory that higher fat would mean less protein to convert and no carbs available which would mean the body breaking down triglycerides and making its own glucose by binding two glycerol cells together (which can make glucose in small amounts). I guessed that this was why high fat seems to work so well because it forced the body to let go of the fat to get the glycerol to make the glucose...
Any thoughts? Anyone heard this before? Anyone want to tell me it's a load of crap so I can stay on the high fat diet? (I don't care if you're making it up! Just tell me!)

That explains the whole thing best although I hope he's wrong.
