Depends on what you mean by carbohydrate?
If your talking pure sugar, yes, but whole wheat bread no, if you cut out the refined sugar then you can eat the bread because your primary source of nutrition is coming from protein and fat which allows you to eat the bread; I’ve done it and it does in-fact work on a ketogenic diet.
Big mistake Bunny. “Healthy Carbs” are what injured me. It is total marking garbage. Wheat and bread have higher glycemic loads and indexes that do a bowl of table sugar. And the nutrition difference is between whole and white is negligible. Do the math. White rice and white flout have no nutrition. Brown rice and whole wheat have double that. Zero times two is still zero. And the glycemic load and index are virtually identical.
Wheat grass? Are you kidding. Grok (my favorite cave man) only ate grains if he accidentally picked up some seeds off a piece of meant he picked up off the ground. Grok would have not even extended the effort of stooping over to pick them. Grok did not eat grass. His/our digestive track is not that of a four chamber cow.
And as far as you fermented seed flour the bacteria is good for you and the fermenting process removes a lot of the toxins in wheat, but is DOES NOT lower the glycemic index or load. I will grant you that you have to ferment what yourself as sour double bread in the market is just white brad with vinegar added.
I will repeat, grains are not historically appropriate in a human diet.
In the future, yo need to go to http://nutritiondata.self.com or similar and check the Glycemic Load of what you are eating or your will NEVER kick the addiction to carbohydrates and will never get over the ill effect they have on you.
