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.
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.
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.
Thus far, we have established what IMO is and how its structure can differ in regard to its carbon bonds. The real question is, “What are the metabolic responses of products that contain these IMOs?” The glycemic index of IMO is very low,[3] however, it has been shown to be nearly completely digested (83 % or more) by enzymes on the small intestinal border.[3] Thus, IMOs should not necessarily be classified as a true fiber but rather as a low glycemic carbohydrate like steel cut oatmeal, at about 3.3 calories per gram.

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.[4] 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.
But do you need that much fiber to stay healthy? Perhaps not. Several different large reviews of dozens of studies have found that eating more fiber than the average person can reduce your risk of dying from both heart disease and cancer by at least 10%[*][*][*]. The benefits of eating fiber in these studies occurred with a total daily fiber intake between 18-26 grams, much lower than the USDA and NAS recommendations.

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.
Even so, keto followers may experience a rise in LDL cholesterol, sometimes called “bad” cholesterol because too much of it can lead to a buildup of plaque in the arteries, which can increase the risk of heart disease. And that’s where fiber can help. However, many high-fiber foods, like beans, fruits, vegetables, nuts, seeds, and whole grains, are also high in carbs, so they're limited on the keto diet.
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?
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.
Most hotels these days include at least a small refrigerator, and some even include a full kitchen and stove. This is great because it allows you to shop locally for some fresh food options. Search online for nearby farmer’s markets or grocery stores and see if you can pick up some local meats or fresh veggies to have in your room. This is more likely to be an option in the warmer months.
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. 

Going on vacation is exciting, until you realize you just started the Keto diet. When you’re headed on vacation, believe it or not, but there are tons of ways you can stick to the Keto diet. Many people would agree when someone says that Keto is a way of life and not just a diet. Before you start on your vacation, you’ll need to keep this in mind. Don’t stress about eating keto when you are on vacation, it is fairly easy to keto on vacation! 
I’ve been on the Keto zone diet for over 2 months and finally feel energy and a sense of fullness. I have logged purposely the meals you suggested in your book however when I test to see how I’m fairing in fat burning with the ketones sticks I come up in the middle. I tried to adjust here and there to see if my percentages are aligning to the 70-15-15 as you suggest but it still comes up in the middle. In other words I’m average in the fat burning process. Is this just stubbornness on my body’s part?I’m slowly loosing weight but slowly. I exercise but that hasn’t changed anything. Thanks for your help!

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.
Non-starchy vegetables are an essential part of the keto diet because they provide essential vitamins and minerals, are packed with antioxidants and provide plenty of fiber. Plus, when you load up on veggies, you are adding volume to your meals so that you feel more satisfied. You are also working to reduce inflammation, increase your antioxidant intake and support the health of your heart.
