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.

A close relative of maltose is a molecule known as isomaltose (typically found in items such as beer and honey). The biggest difference between maltose and isomaltose is that isomaltose is joined together by an α-1,6 chemical bond, rather than an α-1,4 chemical bond. Scientists suspected that by adding a certain enzyme (transglucosidase) to high maltose syrup, they could change the bonds from α-1,4 to α-1,6, thereby making it more resistant to being broken down by the enzymes, as described above, when compared to maltose. Again, while this sounds excellent in theory, it is not necessarily what happens in our bodies. In fact, isomaltose (and thus, IMO syrups used in some of these products) is broken down by certain enzymes on the brush border of the small intestine.[2] Though the α-1,6 bond breaks down slower compared to the α-1,4 bond, these IMO syrups, which often use a blend of di-and oligosaccharides, ultimately metabolize into small amounts of glucose and maltose[2] and thus should be viewed as a slow digesting carbohydrate rather than a true fiber.
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?

The Keto Diet works best if you can maintain it. If your body is continually switching from converting carbs to glucose, instead of converting fat to ketones for energy (which is the process of ketosis, wherein the liver converts fat cells into energy), your weight loss will possibly stall. Consequently, you may find that some health benefits of eating a Keto-friendly diet begin to diminish. Find a healthy balance on your next vacation; with some planning, you can maintain your Keto Diet even when you are out of your routine.
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.
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.

I’m not sure who determined that egg nog is a recipe that only comes around during the holidays, but whoever they are shouldn’t be allowed to make anymore decisions. This is now one of my favorite beverages and seems like an awfully good way to end any night of the year. It’s thick, it’s rich, it’s creamy and low carb, does it get any better? Regardless of whether you are an eggnog drinker, you’ll want to make this keto eggnog for your friends and family this holiday season!  **Cooked Eggnog: If you prefer to cook your egg nog, you can first heat your heavy cream and flax milk in a saucepan, remove from heat and slowly whisk in the lightened color yolks and swerve mixture, and the peaked whites. Once fully combined return to heat and heat through once more prior to chilling.  

To figure out the correct amount of fiber for your body, try experimenting. If you’re on the keto diet, start with 15-20 grams of total dietary fiber per day from a mix of soluble and insoluble fiber for several weeks, then consider adding 3-5 grams at a time as needed to see how you feel. Remember that some people actually feel worse when they boost their fiber intake[*][*][*].

Alex is editor in chief of Bodyketosis, an author, low-carb enthusiast and a recovering chubby guy who reclaimed his health using the ketogenic lifestyle. The need for the keto life began after his aunt and cousin were diagnosed with type 2 diabetes and he was next in line. Through personal experience and extensive scientific research, Alex offers insightful tips for everything keto.
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.

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!
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.[1] 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).

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.” 

One of the most common disaccharides (two monosaccharides joined together) is maltose. Maltose is generated when two glucose molecules are linked to one another by an α-1,4 chemical bond (1st carbon is bound to the 4th carbon, making it easily digestible). The type of bond involved in saccharide linkage is critical, as it determines its ability to become hydrolyzed by the enzymes we described above. As such, the α-1,4 chemical bond, as listed in the above example (maltose), has the ability to become hydrolyzed (broken down).

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.

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.
