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. 
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.
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.
I still crave eggnog as we get closer to Christmas. Luckily, it’s pretty easy to make a keto, sugar free version of eggnog. Keto eggnog is a combination of cream, and/or nut milk, egg yolks and your favorite sweetener. The hardest part is heating iy on the oven slowly to make sure the egg yolks don’t curdle. Even if you do curdle, you can strain them out and you will be left with creamy low carb eggnog.
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.
After I had spent some time thinking about it and reading the labels on every brand of eggnog at Walmart, I decided to try my hand at making my homemade keto eggnog. I won’t lie, I am an eggnog snob, and I have tasted lots of different brands and homemade versions over the year. My favorite brand is Southern Comfort Eggnog, and I have never tasted homemade eggnog that I enjoyed. That’s why I decided not to get excited about this little experiment. I plan to make five different eggnog recipes, and this was my first attempt. I tasted this recipe immediately after making it, and I wasn’t very impressed. Like many eggnogs, I have tried in the past it was bland and didn’t taste like my favorite brand.
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.

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.
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.

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.

One thing you can do for yourself, if you’re on vacation is pack your own food. This may not work if you’re flying overseas, but if you’re sticking to the USA; you should be able to pack your own food without a problem. Of course, sticking to the basics of the Keto diet is one of the smartest things you can do. Protein, high fat, and low carbs! Stick to foods you know are acceptable on the Keto diet.
