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.
IMOs can be made in several ways, but they are primarily derived from a sugar called maltose. IMO is promoted as a prebiotic fiber with a light sweetness profile. Its functional properties (i.e., moisture retention, low viscosity) make it well-suited for nutrition bars, cookies, candies, and the like. In order to fully understand IMOs and how the body processes them, we first need to understand how starches are digested in the body. Starches, also known as polysaccharides, are long and sometimes branched chains of glucose molecules. Initially, starch digestion begins in the small intestine with an enzyme called α-amylase. A-amylase breaks these long glucose chains into much shorter chains, called oligosaccharides, which are composed of anywhere from two to approximately 10 glucose units. Following this, specific enzymes on the brush border of the small intestine break down these oligosaccharides even further, into individual glucose units (monosaccharides) which are then absorbed.
In contrast insoluble fiber, which does not dissolve in water, is inert to digestive enzymes in your upper gastrointestinal tract. While some forms of insoluble fiber (like resistant starch) can ferment in your colon, most insoluble fiber moves through your digestive system relatively unchanged, absorbing water as it goes, eventually adding bulk to your stool and easing your bowel movements.
A lot of people on the Keto diet take their vacation as a way to splurge and eat whatever you want. It’s important to realize that your body isn’t used to the old way of eating, it’s used to Keto. So, yes – you will most likely gain weight back, and gain it back very quickly. Just make sure you know that what you eat matters. If you are going to have treats, then it helps to make sure that 90-95% of what you are eating is Keto friendly and then include your treats in the other 10% of what you are eating. This will help with the getting to carried away eating non keto foods.

Walk around any fitness expo, or even down the “snack bar” aisle of a grocery store, and you are bound to see many varieties of low carb, high protein bars, cookies, candies, and everything in between. Protein bars are in the mainstream right now, and they seem to be everywhere, from the local grocery store to the airport, and even gas stations. Companies have mastered the ability to create something that is pleasing to both the eye and the pallet (i.e., flavors like chocolate chip cookie dough, birthday cake, chocolate brownie, peanut butter, etc.), yet provides ample protein while “low” in carbohydrates. If you attend any fitness or food-related expo, you are very aware that the booths with the longest lines are the ones that are sampling their latest protein bars or “high protein, low carb” treats (cookies, brownies, ice creams, etc.). Nonetheless, in a red ocean market (i.e., market ran by competing industries) that is flooded with these “healthier and high-protein” alternatives, what truly separates one product from another?
Low in carbs and high in fiber, lupini beans (aka lupin beans) are perfect for those on keto who are looking for a high-protein, high-fiber snack. Never heard of them? This yellow legume is hot on the heels of the edamame and fava bean as an on-trend nibble for the health-conscious consumer. One cup of cooked lupini beans contains 4.6 grams of fiber—about 19% of the recommended daily value. However, ready-to-eat branded lupini bean snacks often contain even more. “I've noticed that the amount of carbs/fiber can vary greatly between lupini bean brands,” says Yule. “To make sure that you are choosing a food that is keto-friendly, be sure to check the label.”
