You may need to skip the cake, or at least limit your intake of sweets and carb-heavy vegetables. Know your body and do what makes you feel best. If you don’t think you will be able to get back on the Keto Diet comfortably after having a “cheat day” or “cheat vacation,” then perhaps it might be best to continue eating a strictly Keto-friendly diet.
Taken together, the above studies prompt the question: What is the prebiotic activity of SCF? If it is a true fiber, per our definitions above, then SCF should have a beneficial effect on gut microbiome bacteria. A study performed in 24 adolescents noted an increase in beneficial bacteria (e.g., Bacteroides, Butyricicoccus, Oscillibacter, and Dialister). Furthermore, this was correlated with an increase in calcium absorption upon the consumption of 12 grams of SCF per day for three weeks. An additional study, which administered 8, 14, and 21 grams of SCF over 14 days, found that good bacteria (e.g., Bifidobacteria) increased and peaked at 8 grams per day. This value is nearly identical to inulin, which is considered the “gold standard.” Despite its nearly parallel effects to inulin at 8 grams/day, research has demonstrated that SCF is 3-4 times more tolerable than inulin due to its slower rate of digestibility by the gut bacteria. In fact, 26 grams of SCF barely increased GI symptoms relative to a placebo!
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.

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!
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.
