Following along with the whole yin/yang of fiber, the reduction of cholesterol can also lead to a reduction in androgen production as well, correct? Life is just so many checks and balances...

Blood cholesterol is not the rate limiting step for testosterone production, maybe if levels got stupid low.

lyle, i understand that fiber mixes with the chyme and binds to some of the fat in the large intestine, causing some calories to be excreted.

my question is: would the effect be greatest when co-ingesting a high-fiber and a high-fat food, or would there be no added benefit?

for example, say someone eats the majority of their daily fat intake for breakfast around 7:AM (eggs and bacon, for example), then 12 hours later, eats a high-fiber/low fat dinner (e.g. chicken breast, black beans and broccoli).

would the long interval between the high-fat meal and the high-fiber meal negate any of the "calorie wasting" properties, or does one see the same benefits no matter the timing?

i realize i'm splitting hairs somewhat, but i'm genuinely curious.

thanks

I want you to really think about that one for a few minutes and see what you come up with. Focus on how long you think dietary fat stays in the gut.

I have these Mission brand mini/fajita size tortillas that, if the printed nutrition facts are to be believed, contain "13g total carb, 10g fiber". During the UD2 low carb phase, I'll usually eat a couple of these, sometimes a few, with meat dishes.

I read the article, but I still don't have a clean answer: How should I count these toward carb limits for UD2?
Don't count the fiber? (3 grams each)
Do count it? (13 grams each)
Count it times 0.6, since fiber has about 60% of the calories of normal carbs? (9 grams each)

[edit] Is the answer different depending on soluble/insoluble? (I can't identify the actual fiber component in the ingredients, so I can't say for sure which it is.)

These are huge differences, especially if I eat a few of these things. So, not nitpicking.

--

By the way, I'm a bit skeptical of the numbers. Quest bars have similar numbers, but they're made largely of iso-malto-oligo-saccharides so that makes sense.
The #1 ingredient of these, though, is whole wheat flour. Not sure how we get 10/13ths fiber from there... but let's just say it's true for the sake of the question.

Thanks.

A very well phrased question that bothers me too. I eat TONS of vegetables and brans and I always make questimates and compromises deciding whether or not to count the fiber calories. I usually take the middle route and count 50% on high fiber days.

Peter, thanks, I saw that thread, but the discussion there is just about calorie counting.

The issue of carb counting, for UD2/CKD purposes, is left unaddressed.
