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.
"Once you have a kitchen, you have control over what you purchase and what you eat," Addison Johnson wrote on Dietingwell. "An added benefit of this style of travel, other than the fact that you can stick to your keto diet effectively, is that you get to experience the local side of life. Going to grocery stores, choosing from local ingredients, and cooking for yourself will help make you feel like you’re a part of the culture, instead of only a visitor."

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.”
"If you know where you’re going far enough in advance, you can contact your resort or vacation destination and explain your dietary needs with an employee," they wrote. "The vast majority of destinations, including ours, are opening up their menus to try and make them more friendly to those with food allergies and special dietary needs. While keto/low carb aren’t always on those special menus, the fact that they have special menus at all shows that vacation spots recognize that there are a lot of different dietary needs and are willing to help people who can’t or won’t eat the standard fare."

The increased awareness regarding the importance of fiber, in addition to its distinct metabolic effects, has resulted in a surge of companies switching to an alternative fiber known as soluble corn fiber (SCF). Interestingly, SCF has been available on the US market since 2007 and is used in foods and beverages across the Americas, Europe, and Southeast Asia. SCF is produced through an extensive process: corn syrup is exposed to a suite of enzymes for at least 48 hours, some of which are found in the brush border of your small intestine, as well as the pancreas. Notably, a large majority of the corn syrup contains easily digestible carbohydrates; however, a small portion is, in fact, not digestible. At the end of this enzymatic exposure, a stream of digestion-resistant carbohydrates remains and is subsequently filtered several times. The resulting product is a “true fiber” that contains a mixture of α-1,6, α-1,4, α-1,2, and α-1,3 glucosidic linkages, which, as mentioned above, contribute to its low digestibility.
