Psyllium husk is a type of fiber commonly used as a gentle, bulk-forming laxative. With no net carbs and a whopping 7 grams of fiber per two tablespoon serving, ground psyllium is an easy way to increase fiber intake on the keto diet. “It works great as a binding agent in recipes,” Yule says. “Just make sure to consume it with plenty of water, coconut water, or juice to avoid dehydration.” Add a tablespoon to your beverage, and you’re good to go.
Skimping on fiber isn’t good for your digestive health, as it feeds the good bacteria in your GI tract, something that benefits you beyond adequate bowel movements. “The digestive tract is where your body’s second brain is, and it’s home to the majority of your immune system,” says Elia. “If you’re following keto, it should be one of your biggest priorities to make sure you get adequate fiber to keep your gut healthy and happy,” she adds. And, she notes, high-fat diets slow digestion and decrease GI motility, so it’s especially important to get enough.
Lastly, one of the advertised benefits of IMO is possible prebiotic activity. Prebiotics are critical, as they feed the beneficial bacteria in our digestive system, specifically in the large intestine. These bacteria have several amazing functions, such as lowering body fat, improving insulin sensitivity, and lowering depression. Two “gold standard” prebiotics in the industry are inulin and fructooligosaccharides (FOS). Inulin and FOS are non-digestible carbohydrates that robustly increase beneficial bacteria. The challenge, however, is that both inulin and FOS, due to their rapid digestibility by intestinal bacteria, result in low gastric tolerance, and, ultimately, gastric distress. Additionally, inulin and FOS, when added to protein bars or other goods, may degrade over time into individual sugar units. Regardless, one study comparing inulin to IMOs, found that the prebiotic activity in inulin is 14 times greater than that of IMOs. This is logical because, as you recall from above, approximately 70% to 90% of IMOs are digested. As such, only a small portion of these prebiotic fibers make it to the large intestine, in which two out of three studies have demonstrated that this small portion may indeed have some prebiotic effects.
Whisk 1 cup of the warmed nut milk into the yolk mixture. Then add back into the remaining nut milk in the saucepan. Stir until combined. Continue cooking over low heat until the mixture has thickened and reach about 165 degrees and will coat the back of a spoon. Don’t boil or overcook or else your eggs will curdle. If the eggs do curdle, you can strain the mixture to get rid of the curdled chunks.
We’ve all seen it on food labels: “Only 2 net carbs” or “Low net carbs.” But what does this truly mean? What are net carbs, and why does it matter? Are all net carbs created equal, or are we stretching those claims a bit too much? After reading through this article, I think you will agree that there is a pressing need to educate on the precise definition of net carbs, and what exactly constitutes a true fiber.

Keto Diet practitioners who overeat a little on vacation shouldn’t chastise themselves too harshly. Life is about balance, and the Keto Diet helps practitioners regain control over their eating habits, but it shouldn’t be an overbearing burden. As long as you can get back to your diet plan after vacation, and you don’t use your holiday as an excuse to go back to your old way of eating, eating outside of what your Keto Diet plan recommends doesn’t have to be a huge problem.
Taken together, the above studies prompt the question: What is the prebiotic activity of SCF? If it is a true fiber, per our definitions above, then SCF should have a beneficial effect on gut microbiome bacteria. A study performed in 24 adolescents noted an increase in beneficial bacteria (e.g., Bacteroides, Butyricicoccus, Oscillibacter, and Dialister). Furthermore, this was correlated with an increase in calcium absorption upon the consumption of 12 grams of SCF per day for three weeks. An additional study, which administered 8, 14, and 21 grams of SCF over 14 days, found that good bacteria (e.g., Bifidobacteria) increased and peaked at 8 grams per day. This value is nearly identical to inulin, which is considered the “gold standard.” Despite its nearly parallel effects to inulin at 8 grams/day, research has demonstrated that SCF is 3-4 times more tolerable than inulin due to its slower rate of digestibility by the gut bacteria. In fact, 26 grams of SCF barely increased GI symptoms relative to a placebo!
If you’ve been following a keto diet then you know that it takes a bit of time to get into ketosis. Ketosis is the state in which your body uses ketones, which are created during the breakdown of fats in the liver, as a fuel source to give you energy. If you eat carbs then your body will use glucose that comes from the carbs as the main source of fuel.
As observed by the graphs above, in contrast to the IMOs in which blood glucose rapidly increased to 125 mg/dL, SCF did not elicit any blood glucose response. In addition, while insulin was elevated during the IMO condition, it actually tended to go down in the SCF condition! Despite the results from the blood glucose and insulin responses, the breath hydrogen assay will distinguish which is a “true fiber.” Our data below clearly indicates that SCF indeed passes into the large intestine, as indicated by the large breath hydrogen response. In stark contrast, IMOs do not.
The increased awareness regarding the importance of fiber, in addition to its distinct metabolic effects, has resulted in a surge of companies switching to an alternative fiber known as soluble corn fiber (SCF). Interestingly, SCF has been available on the US market since 2007 and is used in foods and beverages across the Americas, Europe, and Southeast Asia. SCF is produced through an extensive process: corn syrup is exposed to a suite of enzymes for at least 48 hours, some of which are found in the brush border of your small intestine, as well as the pancreas. Notably, a large majority of the corn syrup contains easily digestible carbohydrates; however, a small portion is, in fact, not digestible. At the end of this enzymatic exposure, a stream of digestion-resistant carbohydrates remains and is subsequently filtered several times. The resulting product is a “true fiber” that contains a mixture of α-1,6, α-1,4, α-1,2, and α-1,3 glucosidic linkages, which, as mentioned above, contribute to its low digestibility.
