Sweeteners To Avoid On Keto: Sugar-Free But Not Keto-Friendly

Sugar-free sweeteners can be a great way to satisfy a sweet tooth while on the keto diet. However, not all sugar substitutes are created equal, and some may even kick you out of ketosis. Here's a guide to help you navigate the world of keto-friendly sweeteners and choose the best options to maintain your ketogenic lifestyle.

When it comes to sweeteners, the keto-approved options include stevia, monk fruit, erythritol, xylitol, and sucralose. These sweeteners have little to no impact on blood sugar levels, are low in calories and net carbs, and are generally recognised as safe for consumption. Stevia, for example, is derived from the Stevia rebaudiana plant and is 30-150 times sweeter than sugar. Monk fruit, a natural sweetener from Southeast Asia, contains antioxidants and is 100-250 times sweeter than sugar. Erythritol, a sugar alcohol with a similar structure to sugar, has been shown to have dental benefits and no impact on blood sugar. Xylitol, another sugar alcohol, is as sweet as sugar but with fewer calories and carbs. Finally, sucralose is a zero-calorie artificial sweetener that is 400-700 times sweeter than sugar.

On the other hand, there are sweeteners that should be limited or avoided on a keto diet. These include aspartame, which has been controversial due to safety concerns; naturally derived sugars like honey, maple syrup, and agave, which are high in net carbs; maltodextrin, a sweetener that can spike blood sugar and negatively impact gut health; and coconut and brown sugar, which, despite having some nutrients, still contain a significant amount of net carbs.

When choosing a keto-friendly sweetener, it's best to opt for stevia or monk fruit as they have zero net carbs and minimal to no effects on blood sugar. Remember to always check the labels for hidden additives that might increase the net carb count.

Stevia is a natural sweetener with little to no calories or carbs

Stevia is a natural sweetener that has been used for hundreds of years. It is extracted from the leaves of the Stevia rebaudiana plant, which is native to South America. The active compounds in stevia are steviol glycosides, which are around 200 to 400 times sweeter than sugar.

Stevia is a no-calorie sweetener, meaning it has little to no calories or carbs. This is because humans cannot metabolise the glycosides in stevia, so it has zero calories. It is also heat-stable, pH-stable, and not fermentable.

Stevia is often used as a sugar alternative in food and beverages. It can be used in baked goods, although it may slightly alter the texture and volume of the final product. It is also used in tabletop sweeteners, such as Truvia, Pure Via, and Splenda Naturals Stevia Sweetener.

Stevia has been deemed safe for consumption by the U.S. Food and Drug Administration (FDA) and other global health authorities. It does not raise blood glucose levels and can be safely consumed by children and those who are pregnant or breastfeeding. It may also have health benefits, such as anti-hypertensive, anti-obesity, anti-diabetic, antioxidant, anti-cancer, anti-inflammatory, and antimicrobial effects.

However, stevia may have some side effects, such as bloating, dizziness, nausea, and numbness. It can also lower blood sugar and blood pressure, so it should be used with caution by those taking insulin or blood pressure medication.

Monk fruit is a natural sweetener with zero calories, carbs and no impact on blood sugar

Monk fruit is a natural sweetener with zero calories, carbs, and no impact on blood sugar. It is a small, round fruit grown in Southeast Asia and has been used for centuries in traditional Chinese medicine. The monk fruit, also known as lo han guo or Swingle fruit, is native to Southern China. The sweetener is made by removing the seeds and skin of the fruit, crushing it, and then filtering and extracting the sweet portions into liquid and powdered forms. Monk fruit is 100-250 times sweeter than sugar, so only a small amount is needed to achieve the same level of sweetness. It is often blended with erythritol, a sugar alcohol with zero calories, to create a product that looks and tastes more like table sugar.

Monk fruit sweetener is safe for consumption and is Generally Recognized As Safe (GRAS) by the U.S. Food and Drug Administration (FDA). It does not cause blood sugar spikes and is safe for people with diabetes. It is also safe for pregnant and breastfeeding women and children. Monk fruit sweetener is also keto-friendly and can be used in baked goods due to its stability at high temperatures.

Monk fruit sweeteners can be used in a wide range of beverages and foods, including soft drinks, juices, dairy products, desserts, candies, and condiments. It is a good alternative to sugar for those looking to reduce their calorie and carb intake and manage their weight. However, it is important to note that monk fruit sweeteners may cause digestive issues in some individuals, similar to other sugar alcohols. Overall, monk fruit is a natural and healthy sugar alternative that can be used in various applications.

Erythritol is a sugar alcohol with little to no calories or carbs and no impact on blood sugar

Erythritol is a sugar alcohol, a class of compounds often used as low-calorie sweeteners in sugar-free or low-sugar products. It is found naturally in small amounts in fruits and vegetables, and it can also be produced commercially by fermenting glucose from corn or wheat starch.

Erythritol has a taste similar to table sugar but with only 6% of the calories. It has zero calories and is about 60% to 80% as sweet as table sugar. It is quickly absorbed by the small intestine and excreted through urine within 24 hours, which is why it does not have a chance to metabolize and turn into energy in the body. This also means that erythritol does not spike blood sugar or insulin levels, making it an excellent alternative for people with diabetes.

Erythritol is also beneficial for dental health. Unlike sugar, it does not feed the bacteria that cause cavities. In fact, it suppresses the growth of these bacteria directly and is more effective at inhibiting their growth than other sugar alcohols like xylitol and sorbitol. Several studies have shown that erythritol reduces plaque and harmful bacteria, leading to improved oral health.

However, consuming large amounts of erythritol may cause digestive issues such as bloating, cramping, excess gas, and diarrhea. It may also be associated with blood clots and an increased risk of heart attack and stroke, although more research is needed to confirm these potential side effects.

Overall, erythritol is a good alternative sweetener for those looking to reduce their sugar intake, especially for people with diabetes or those wanting to improve their dental health.

Xylitol is a sugar alcohol with minimal calories and carbs

Xylitol has a similar level of sweetness to sugar but with a fraction of the calories. It has a glycemic index (GI) of 7, whereas regular sugar's is 60–70. This means that consuming it does not cause spikes in blood glucose or insulin levels in the body. For this reason, xylitol is a good sugar substitute for people with diabetes.

Xylitol is a common ingredient in sugar-free chewing gum, candies, mints, diabetes-friendly foods, and oral-care products. It is also used as a table-top sweetener and in baking.

Xylitol is generally well tolerated, but some people experience digestive side effects when they consume too much. It can cause gas, bloating, and diarrhea. However, the body seems to adjust well to xylitol. If you increase the intake slowly and give your body time to adjust, you likely won't experience any negative effects.

Xylitol is highly toxic to dogs. When dogs eat xylitol, their bodies mistake it for glucose and start producing large amounts of insulin. This can lead to hypoglycemia, or low blood sugar, and even death.

Sucralose is an artificial sweetener with zero calories and carbs

Sucralose is an artificial sweetener that is not metabolised, meaning it passes through the body undigested and does not provide any calories or carbohydrates. It is approximately 600 times sweeter than regular sugar, so only a tiny amount is needed to replace sugar in recipes.

Splenda is the most common sucralose-based sweetener on the market and is popular because it lacks the bitter taste found in many other artificial sweeteners. While sucralose itself is calorie-free, Splenda contains maltodextrin and dextrose, two carbohydrates that supply about 3 calories and 1 gram of carbohydrates per packet.

Sucralose is generally considered safe when consumed in moderation. However, research on its long-term effects has produced mixed results. Some studies have linked sucralose consumption to negative health effects, while others have found no significant impact.

When it comes to baking, there is conflicting evidence regarding the stability of sucralose at high temperatures. Some studies suggest that sucralose may break down and interact with other ingredients at high temperatures, potentially forming harmful compounds. However, other studies refute this claim and conclude that sucralose is safe for cooking and baking.

Overall, sucralose is a popular choice for those following a ketogenic diet as it contains zero calories and carbohydrates. However, it is important to be mindful of the potential health effects and consider using alternative sweeteners when cooking or baking at high temperatures.
