Depending on where you are going on vacation, you may have a measure of control over what you will be eating. For Keto dieters who are staying at a hotel and will be traveling from tourist spot to tourist spot, check with your hotel and see what kind of meal options their restaurant offers or whether there’s a continental breakfast. There may be fewer Keto-friendly options to choose from, but you will likely be able to find something to enjoy. Also, when out traveling, be sure to stop at grocery stores and purchase some Keto-friendly snacks that travel well, such as cured meats or cheeses, which can help keep you from overindulging.
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. 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).
Seeds are another high-fiber food that you can eat on keto, but only occasionally to stay in ketosis. Full seeds, ground seeds and seed butters will help to increase your fiber intake and minimize keto flu symptoms like constipation. Plus, they supply important nutrients, including essential fatty acids and protein, and are known to support cardiovascular health.
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. 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.
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.
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.

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.
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.
