7g of fiber per day isn't enough for anybody, you should get (as a rough estimate) about 10g per 1000 kcal

I don't know the proper ratios but 50/50 wouldn't be a bad starting point. I think the main thing to realize is that both are required for good bowel movement, you can't have just 30g of insoluble fiber per day

I was just speaking ratios.

I didn't mean that would be it..

Anyhow I can't find insoluble fiber in bulk. :'(

i figured that, but still just saying.

e: i dont think ratios are very specific anywho, i think your intake will vary day to day but in the end as long as you get a variety of fibers you'll be fine

- study notes that a vegetarian diet is associated with poorer health.

The first study gives mechanistic insight into vegetarian type diets (or virtually no cholesterol) and how the attenuated plasma cholesterol levels correlate with an increased incidence of depression, and the correlation became more significant/the discrepancy grew as age increased.

following with that.. Robin Williams was a vegan...

"The contribution of ketone bodies to basal and activity-dependent neuronal oxidation in vivo."

http://www.ncbi.nlm.nih.gov/pubmed/24780902

- showed a 62% contribution

then this: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2874681/
says that there's a 10% reduction in glucose use per 1mM of plasma ketone bodies

The first link noting 62% also noted BHB levels of 6-13mM.. actual levels reached during dietary ketosis won't reach that high. Thus, it seems the brain, even under ketosis, still uses a considerable/majority amount of glucose

I'm guessing from AA gluconeogenesis despite ketogenic diets being high in fat, which means lower blood AA but that'd be a stretch

Well, if the brain on average requires 100g of glucose per day, I guess it doesn't need too much glucose after the ketones.
Besides that, I'm still wondering how people say that a keto diet is muscle sparing.. I can't wrap my head around it, it seems erroneous though. The glycerol from FAs only give a small contribution to the glucose pool.. and with <25g of CHO being consumed per day, the rest MUST come from AAs, correct? Where else would it come from? I mean certainly there will be massive fatty acid contribution to most systems, plus FA conversion to ketones accounting for the brain, but I can't figure how that could be protein sparing seeing that the skeletal muscle still needs it during exercise, plus strictly maintaining your plasma glucose levels in a relatively strict range constantly.

Looks interesting. I'll likely read it in the next few days and give my thoughts.

In other news, been studying a massive amount of neuroscience lately
enoying it a lot too.. the subject is so much more enthralling than other avenues of biology (imo).. I can definitely tell this is what I'd like to go into professionally, am excite! This undergrad shit is literally an utter waste of time very very frustrating.
