I had to powerhouse my way through Taubes today as it's due back at the
library and can't be renewed as there's a waiting list for it cause they
only got 5 copies.
I was very impressed at his ability to cover the Kreb's cycle,
lipolysis, etc and manage to translate it to laymen's language. My
college biochemistry textbook was easily twice as thick as this and
didn't have to "translate" for laymen. Course, it had a lot more
details, but... the thing is no one remembers all that stuff anyways.
Most you remember is stuff like the Kreb's cycle produces ATP in the
mitochondria... and Taubes manages to cover all the bits one actually
remembers. It might be somewhat tough reading for some laymen, but he
does manage to make the basic metabolism of carbohydrate and fat pretty
accessible for non-chemists (he has much less on the metabolism of
protein though).
He doesn't just discuss insulin and I'm not sure why people come away
from the book thinking that. He makes a big deal out of the importance
of the hypothalamus-pituitary axis in regulating both appetite and fat
storage. He discusses the importance of the sex hormones with regards
to fat storage also. He provides a summary of the hormones known to
regulate fat storage as of 1965 includes: epinephrine, norepinephrine,
ACTH, glucagon, TSH, melanocyte-stimulating hormone, vasopressin and
growth hormone as well as insulin. That being said, he doesn't address
adrenal hormones beyond epinephrine and norepinephrine hardly at all.
He discusses some experiments with rats with their adrenals surgically
removed, but it's basically about aldosterone (though he doesn't refer
to the hormone by name). Not a word about cortisol anywhere.
I'm not sure why people come away from the book thinking he says not to
exercise. Rather, he points out that fat storage is related to calories
in and calories out pretty directly. He simply points out there's some
confusion about what is the cause and what is the effect - which
variables are independent in that equation. He also points out that
exercise is not the entirety of "calories out" as basal metabolism is
also effected. He seems to believe that excess fat storage causes a
reduction in both basal metabolism and the natural desire to exercise -
lean people burn calories at a higher rate even when sleeping and
naturally enjoy moving more. But nowhere does he say that exercise is
not good.
I think this is the best and most thorough low-carb book I've ever read.
Lots of information I've run across in many different places is all
organized here, as well as a few studies I wasn't familair with. Beats
the heck out of Protein Power, which is no longer my favorite low-carb
book now that GCBC is available. In between finishing reading it and
returning it to the library, I ordered a copy from Amazon as it's a good
reference book that should sit on my desk next to Bernstein and my book
of food counts.
