Carbs

[Roughneck82]

When we are counting our macros, does fiber count as a carb? I see on different things I eat, take quest bars for example. 21 carbs, 18 are fiber. Then underneath it says only 3 countable carbs. So are we only counting what converts into sugar?

to get technical, they are right. dietary fiber that is non digestible does not contribute to glucose in the blood stream and therefore do not offer calories to the metabolic process.

this is why celery has "negative" (net) calories.

Ok good to know, so does that go for all fiber? And thanks for the macro counter T-roman

You can either count the fiber calories or not count them but be consistent whichever method you use. Fiber also is partially digestible and contains around 2cals/gram. I personally choose to count fiber

[Times Roman]

there are two types of fiber

1) Soluble fiber (absorbs water) - slows down the release of glucose in the blood stream (reduces the GV of food)
2) Insoluble fiber (does not absorb water) - speeds up the throughput of food through the digestive tract

neither type of fiber increases or provides caloric content. Therefore, NO fiber should be counted as a carbohydrate when counting carbs that contribute to the release of glucose into the blood stream nor as contributing any calories.

You're welcome for the macro calculator

Newsflash: Fiber Provides Calories to Humans
But there is another effect of fiber on energy balance that often goes unappreciated. Backing up, it’s often stated that fiber provides no calories to the body since humans lack the enzymes necessary to digest it. This has often been taken even further to claim that high-fiber vegetables are ‘negative calorie foods’, that is they take more calories to digest than they provide (assumed to be zero).
Here’s the thing: it’s not true. Not entirely anyhow.
Above I discussed the issue of fermentation of some types of fiber to short-chain fatty acids which are then reabsorbed by the body. Well, those fatty acids provide calories to the body. While there is still some debate in the area, researchers have assigned a caloric value to fiber of 1.5-2 cal/gram (depending on the specific type).
Admittedly this is an average and will depend on the specifics of the diet and the type of fiber but, simply, the idea that fiber provides no calories to the body is not true. While the caloric value of fiber is still lower than starchy carbohydrates (4 cal/g), it is not zero.

I've heard this before. And I can appreciate Lyle's reputation. What I haven't seen is anything other than his opinion on the matter. Are there any authoritative reference materials through NCBI or equivalent?

I ask because the general body of information in the medical community has it that fiber, due to it's nature and cellulose like composition, yields zero calories. True, some forms of fiber are highly fermentable, and thus can yield some calories, but to say on average all fiber is between 1 and 2 calories seems excessive.

Fermentation of fiber, blah blah blah. Then we get into sugar alcohols and impact. Screw that. Pick a method, stick with it, adjust accordingly for YOU! How you respond. This shit is spinning your wheels when you could be training, eating,or resting and growing.
End rant.

blah blah blah?

...well, I guess that settles that!

(can't argue with the blah's)
