Breath Hydrogen is an assay that indicates in “real-time” whether or not a particular nutrient is being digested. Upon consumption of a standard carbohydrate (e.g., rice), you can see that it is broken down in the small intestine, and, subsequently, blood glucose rises. If the carbohydrate is not digested in the small intestine, it moves into the large intestine. This indicates that it is a “true fiber.” In the large intestine, bacteria digest the fiber through a process called “fermentation.” In doing so, the bacteria produce hydrogen ions (H+) that circulate into the bloodstream, through our lungs, and is then exhaled outward. We monitored a subject consuming either IMOs or SCF respectively and then tracked the variables listed above for 150 minutes following consumption.

One of the first studies to examine IMO syrups[2] had six subjects consume 25 grams of IMO syrup. These researchers found that glucose levels increased from 109 mg/dL pre-ingestion to a peak of 136 mg/dL 30 min post-ingestion. Additionally, insulin rose to nearly parallel levels with that of glucose from 4.8 μU/mL pre-ingestion to nearly 32 μU/mL at 30 min post-ingestion. These values clearly indicate that some digestion is occurring. Furthermore, these researchers found that IMO was about 83% as digestible as maltose under resting conditions and about 69% as digestible after the exercise period. Taken together, this suggests that a large majority of the carbohydrate in the IMO syrup was, in fact, digested, absorbed, and metabolized.


Dr. Ryan P. Lowery is the CEO of Ketogenic.com, author of The Ketogenic Bible, President of the Applied Science and Performance Institute and KetoPhD™. His mission  is to spread awareness around the Ketogenic Lifestyle and its’ many benefits beyond body composition. He earned his BS and MS in exercise physiology and exercise and nutrition science from the University of Tampa and completed his doctorate work at Concordia University in Health and Human Performance with a focus on “The Effects of a Well-Formulated Ketogenic Diet and Exogenous Ketone Supplementation on Various Markers of Health and Body Composition in Healthy and Diseased Populations.” Over his career, Ryan has published over 150 papers, abstracts, and book chapters on human performance and sports nutrition and has dedicated his life to educating the masses. In his free time, Ryan enjoys spending time with his best friend, Scoot the Keto Pup, jet skiing, and traveling around the world. The way to his heart is through a good glass of wine and Keto desserts.
Another significant benefit of the ketogenic diet is that you avoid the big spikes in blood glucose levels caused by excessive carbohydrate consumption. Because some of the benefits of eating dietary fiber come from improved glycemic control, your fiber needs may be further reduced on the keto diet since your glycemic control comes from eating very few carbs.
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.
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.
