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.
A close relative of maltose is a molecule known as isomaltose (typically found in items such as beer and honey). The biggest difference between maltose and isomaltose is that isomaltose is joined together by an α-1,6 chemical bond, rather than an α-1,4 chemical bond. Scientists suspected that by adding a certain enzyme (transglucosidase) to high maltose syrup, they could change the bonds from α-1,4 to α-1,6, thereby making it more resistant to being broken down by the enzymes, as described above, when compared to maltose. Again, while this sounds excellent in theory, it is not necessarily what happens in our bodies. In fact, isomaltose (and thus, IMO syrups used in some of these products) is broken down by certain enzymes on the brush border of the small intestine.[2] Though the α-1,6 bond breaks down slower compared to the α-1,4 bond, these IMO syrups, which often use a blend of di-and oligosaccharides, ultimately metabolize into small amounts of glucose and maltose[2] and thus should be viewed as a slow digesting carbohydrate rather than a true fiber.
Taken together, previous research in combination with our lab’s current research may argue that IMOs should not be classified as a “true fiber.” Rather, IMOs should be viewed as a very low glycemic carbohydrate source, much like steel cut oats. In essence, if you see a low-carb snack that has 20 grams of IMO fiber, it is likely that approximately 16 grams of this fiber will act as a slow-digesting carb, and four grams will act as an indigestible fiber. Those who are on a ketogenic diet should be aware of these fibers and proceed with caution when consuming them in large amounts, as they could raise both blood glucose and insulin levels. A more ketogenic-friendly fiber is SCF, which has been demonstrated to act as more of a true fiber. Additionally, SCF is very tolerable in the gut despite its profound prebiotic activity. It is important to keep in mind that everyone is metabolically different, so if you are consuming food items with these fibers in them, be sure to monitor blood glucose and ketone readings to find how each of these fibers personally affects you.

There are two general categories of dietary fiber: soluble and insoluble. Fibrous foods typically contain both soluble and insoluble fibers. As a society, we understand the importance of fiber, including the benefits related to lowering body fat, decreasing the prevalence of diabetes, improving insulin sensitivity, decreasing the risk of heart disease and increasing satiety, as well as the beneficial bacteria in our digestive system.[1] Unfortunately, less than 5% of Americans actually meet the 30 gram per day recommended intake. To help increase fiber consumption, an increasing number of companies have developed a host of delicious, low-carb, high-fiber treats. Despite this, it is important to understand how our bodies process two of the most common “fibers” on the market that are used in these treats: isomaltooligosaccharides (IMOs) and soluble corn fiber (SCF).


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.
One study compared the glycemic response of SCF to the glycemic response of glucose in 12 healthy adults during a randomized, controlled, crossover study.[6] The findings of this study revealed that SCF had a significantly lower incremental glucose and insulin response than that of the glucose control. Additionally, another study observed a significant lowering effect on postprandial (during or after food consumption) blood glucose and insulin (coinciding with an increase in fat oxidation) upon consumption of 55 grams of SCF in 18 overweight adults, compared to a full calorie control.

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.


Not all the extra ingredients are keto friendly. Some of the dressing mixes are high in carbs as well as some of the extra ingredients such as tortilla strips and croutons. Depending upon how many carbs you eat in a day you may want to avoid those mixes, or at least remove some of the ingredients, and stick with the mixes that only contain salad greens.

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.

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.
If you are aware of what you’re eating throughout the day, you can better plan for indulgences. When traveling to a place that is known for their cuisine, enjoy eating while remaining balanced about your diet. Instead of getting a sweet all to yourself, maybe share it with whoever you are going. By sampling small portions of food, instead of overeating till you feel sick, you can enjoy your vacation food while still keeping your Keto Diet in mind. Alternatively, be sure to get as much exercise as possible (walk to destinations instead of taking a bus or driving), and the extra exertion will help use up any extra calories (or carbs) that you may eat.

It can be hard to eat at a restaurant and understanding what everything is made out of. One of the most basic things you can do is stick to the basics. Most people on the Keto diet don’t eat bread, pasta, or rice…easy enough. Of course, staying away from items that are heavy in sugar in carbs is also a good idea. Most people can look at a traditional dish and gauge whether something has a lot of carbs or not.
Eggnog is delicious all year round, but far from keto friendly. However, I found a simple way to mimic the milk that is normally found in eggnog, so that you can’t even tell the difference! If you use heavy whipping cream as the majority of the base and lighten it up with some flax, almond or cashew milk you’ll get the perfect thickness for your eggnog. Aside from the milk the rest is perfectly suited for a low carb diet, including the optional whiskey you add *wink face*.
Alex is editor in chief of Bodyketosis, an author, low-carb enthusiast and a recovering chubby guy who reclaimed his health using the ketogenic lifestyle. The need for the keto life began after his aunt and cousin were diagnosed with type 2 diabetes and he was next in line. Through personal experience and extensive scientific research, Alex offers insightful tips for everything keto.
To figure out the correct amount of fiber for your body, try experimenting. If you’re on the keto diet, start with 15-20 grams of total dietary fiber per day from a mix of soluble and insoluble fiber for several weeks, then consider adding 3-5 grams at a time as needed to see how you feel. Remember that some people actually feel worse when they boost their fiber intake[*][*][*]. 

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.

i am an eggnog fangirl too! i like to separate the egg yolk from the whites, blend everything except the whites, whip the egg whites till stiff then fold into the nog for a frothier fuller experience. nutmeg ground on top, of course! i never tried whipping the cream first. might be a little too thick, but also could be fun! esp if you use this to top coffee w a little rum or keto kahlua!
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.
This recipe has been highly requested as of late, so we figured we should have our go at it so you can enjoy the holidays to their full extent this year! Our Keto Eggnog is not only easy to make, but replicates the eggnog you use to drink pre-keto to a tee. I’ll be honest, I’ve never had eggnog, but Matt used to drink it every year and couldn’t stop raving about how exact our keto version tastes. Matt isn’t quick to give a compliment so I think it’s safe to assume we have a winner with this recipe!
