Zero-Calorie Sweetener: Friend Or Foe On Keto?

The keto diet is a low-carb, high-fat diet that aims to put the body into a metabolic state called ketosis, where it burns fat for fuel instead of carbohydrates. This means that keto-friendly foods and ingredients are typically those that are low in carbs and sugars. So, what about zero-calorie sweeteners? Are they keto-friendly?

Zero-calorie sweeteners, also known as non-nutritive sweeteners, are indeed suitable for a keto diet. These sweeteners contain few or no calories and sugars, so they won't raise your blood sugar levels or kick you out of ketosis. Some examples of zero-calorie sweeteners that are keto-friendly include stevia, monk fruit, erythritol, xylitol, and yacon syrup. These sweeteners can be used to add sweetness to keto-friendly foods and drinks without compromising the benefits of the keto diet.

However, it's important to note that not all zero-calorie sweeteners are created equal. Some may contain fillers or additional ingredients that can affect blood sugar levels. For example, some stevia products may be mixed with maltodextrin, dextrose, or polydextrose, which can impact blood sugar. Additionally, the sweetness of zero-calorie sweeteners can vary, with some being much sweeter than sugar, so it's important to use them in the appropriate amounts.

While zero-calorie sweeteners can be a helpful tool for managing carb and sugar intake on a keto diet, it's always a good idea to consume them in moderation and check product labels to ensure they align with your keto goals.

Natural Sweeteners: Stevia, Monk Fruit, and Yacon Syrup are natural, zero-calorie sweeteners that are keto-friendly

Natural Sweeteners: Stevia, Monk Fruit, and Yacon Syrup

Stevia, monk fruit, and yacon syrup are natural, zero-calorie sweeteners that are keto-friendly. These sweeteners are derived from plants and have been used for various purposes for hundreds of years. They offer a range of health benefits and are excellent alternatives to sugar for people on the keto diet.

Stevia

Stevia is a natural sweetener derived from the Stevia rebaudiana plant, a shrub native to South America. It has been used by natives for over 200 years and was adopted as a sweetener by the Japanese in the 1970s. The sweetness in stevia comes from 11 types of steviol glycosides, which are compounds that provide health benefits in addition to its unique sweetness.

Stevia is 300 times sweeter than sucrose (table sugar), so only a tiny amount is needed to achieve the same level of sweetness. It is available in both liquid and powdered forms and can be used to sweeten drinks, desserts, and other recipes.

Monk Fruit

Monk fruit, also known as Lo Han Guo or siraitia grosvenorii, is a green gourd grown in Southeast Asia, particularly southern China and Thailand. It has been used in Eastern medicine for centuries and is known for its incredibly sweet taste. Monk fruit contains compounds that are 250 times sweeter than regular sugar, yet it has zero calories and does not negatively affect blood glucose levels.

Monk fruit sweetener is made from the fruit and is available in liquid, granule, and powdered forms. It can be used in keto baking, as a sweetener in tea and coffee, or added to smoothies. Monk fruit is considered safe by the FDA and provides several health benefits, including anti-inflammatory and anti-cancer properties.

Yacon Syrup

Yacon syrup is derived from the roots of the yacon plant, a tuber widely grown in South America. The roots are crushed to release juice, which is then filtered and evaporated to create a thick syrup. Yacon syrup has a sweet taste and an amber color, similar to molasses.

Yacon syrup is packed with prebiotic fiber, which feeds good gut bacteria and may offer potential health benefits such as stabilizing blood sugar levels and promoting weight loss. It also contains antioxidants and has potential anti-cancer properties, according to early studies.

Yacon syrup can be used as a low-carb substitute for honey, maple syrup, corn syrup, brown sugar, or molasses. It is a good option for keto baking as it adds moisture and viscosity without the high sugar content of other sweeteners.

Stevia, monk fruit, and yacon syrup are excellent natural, zero-calorie sweetening options for individuals on the keto diet. They offer a range of health benefits, from improved oral and liver health to reduced inflammation and potential anti-cancer properties. These sweeteners can be used in a variety of recipes, from beverages to baked goods, making them versatile and healthy alternatives to sugar.

Sugar Alcohols: Erythritol is a popular sugar alcohol and zero-calorie sweetener often used in keto products

Erythritol is a sugar alcohol, a class of naturally occurring compounds that stimulate the sweet taste receptors on your tongue to mimic the taste of sugar. It is often used as a zero-calorie sweetener in keto products.

Erythritol is found naturally in some fruits and vegetables, but it is also commercially manufactured in a lab. It has around 70% of the sweetness of regular sugar but only about 5% of the calories, with just 0.2 calories per gram. This means it can be used as a low-calorie sweetener in food products.

Erythritol is popular in keto products because it has a negligible effect on blood sugar levels. When you eat sugar, your body breaks it down into smaller molecules that are absorbed into your bloodstream, causing your blood sugar levels to rise. However, your body cannot fully break down and absorb carbs from erythritol and other sugar alcohols, so they cause a much smaller rise in blood sugar levels. This makes them suitable for people on a keto diet, who need to keep their blood sugar levels low.

Erythritol is also popular in keto products because it is well tolerated by the body and doesn't usually cause the digestive issues associated with other sugar alcohols. This is because it has a smaller molecular weight, so it is absorbed and broken down more easily by the body.

Erythritol can be used in both baking and cooking and can be substituted for sugar in a wide variety of recipes. It is often used in keto baked goods and drinks. However, it can have a cooling effect on the tongue, which may be unpleasant in large doses, so some people choose to avoid using it in baked goods.

Artificial Sweeteners: Artificial sweeteners like aspartame are best avoided on keto due to potential health concerns

While on a keto diet, it is best to avoid artificial sweeteners like aspartame due to potential health concerns. Instead, opt for natural, low-carb sweeteners like stevia, monk fruit, erythritol, xylitol, and yacon syrup. These alternatives can help you maintain your keto lifestyle without compromising your health.

Artificial sweeteners are often associated with the "keto trap," where people replace sugar with these zero-calorie options, thinking they are healthier. However, this can lead to overconsumption and negatively impact your health. Some artificial sweeteners have been linked to an increased risk of heart disease, with studies showing a correlation between their consumption and higher chances of heart attacks and strokes. Additionally, they may also affect your gut bacteria and contribute to metabolic issues, weight gain, and insulin resistance.

Natural, low-carb sweeteners, on the other hand, can be a better alternative. Stevia, for example, is a natural sweetener derived from the Stevia rebaudiana plant. It has zero calories and carbs and is recognised as safe by the FDA. Monk fruit is another excellent option, as it is also a natural sweetener with zero calories and carbs. It is recognised as safe and can be used as a sugar substitute in various recipes.

Erythritol, a sugar alcohol found naturally in fruits and fungi, is generally well-tolerated and doesn't cause the same digestive issues as other sugar alcohols. Xylitol, another sugar alcohol, is as sweet as table sugar but has fewer calories and carbs. It can be used to sweeten coffee, tea, and smoothies. Yacon syrup, derived from the roots of the yacon plant, is another natural sweetener with half the calories of table sugar.

While these natural, low-carb sweeteners are better options than artificial ones, it's important to remember that even these should be consumed in moderation. The keto diet is meant to reduce your sugar intake and reset your taste preferences, so you may find that your "need" for sweeteners decreases over time.

Sweeteners to Avoid: Maltodextrin, maltitol, sorbitol, and honey are examples of sweeteners that can kick you out of ketosis

Sweeteners to Avoid

Maltodextrin

Maltodextrin is a highly processed sweetener derived from starchy plants like rice, corn, wheat, or potatoes. It is not keto-friendly, as it causes blood sugar spikes and insulin spikes, even in small amounts. It has a high glycemic index of 110, compared to 65 for regular table sugar. This means it can quickly push you out of ketosis. It is often found in dietary supplements, sports performance gels, and artificial sweeteners, as well as some powdered stevia products.

Maltitol

Maltitol is a sugar alcohol, or polylol, that is commonly used in "sugar-free" and "keto-friendly" products. However, it has serious drawbacks for those on a keto diet. It increases blood glucose levels and acts as a laxative, causing gas and diarrhea. It is best to avoid products containing maltitol to maintain ketosis.

Sorbitol

Sorbitol is a sugar alcohol that is 60% less sweet than regular sugar. While it is approved by the FDA and is diabetic-friendly, it is not 100% keto-friendly. It is high in net carbs, with 65 grams of net carbs per 100 grams, and can kick you out of ketosis if consumed in large amounts. It can also cause gastrointestinal issues such as bloating, cramping, and diarrhea, and may negatively interact with certain medications.

Honey

Honey, although a natural sweetener with antioxidants and nutrients, is high in calories and carbs. A small amount of honey, such as half a teaspoon, can contain 3-4 carbs. While this may not be enough to kick you out of ketosis, larger amounts of honey can interfere with a keto diet.

Best Keto Sweeteners: A combination of erythritol, monk fruit, and stevia is often recommended as the best-tasting and most versatile option for keto

Erythritol, monk fruit, and stevia are all keto-friendly sweeteners that can be used as substitutes for sugar in various recipes.

Erythritol is a sugar alcohol that is about 60% to 80% as sweet as table sugar but contains zero calories. It is recognised as safe by the FDA and does not cause spikes in blood sugar levels or promote tooth decay. Erythritol can be used as a substitute for table sugar in beverages and some recipes. However, it may not be suitable for baked goods due to its cooling effect on the tongue, which can be unpleasant in large doses. Erythritol is also an ingredient in many stevia products.

Monk fruit is a natural sweetener that is 100-250 times sweeter than table sugar but contains no calories or carbs. It is generally recognised as safe and can be used in salad dressings, drinks, and baked goods. Monk fruit is often blended with other sweeteners, such as erythritol, to balance out its sweetness and improve taste.

Stevia is a low-carb sweetener that is 200-400 times sweeter than table sugar. It is generally recognised as safe and can be used in coffee, tea, and other beverages. However, it may not work well in large quantities, such as in baked goods. Stevia may also have potential side effects, such as lowering blood sugar and blood pressure, so it is important to consult a healthcare provider before consuming it.

Combining erythritol, monk fruit, and stevia can be a good option for keto dieters as it provides a versatile and tasty sweetening option. Erythritol can help balance out the sweetness and improve the texture of monk fruit and stevia blends. Additionally, monk fruit and stevia can add sweetness to erythritol, which is milder in flavour. However, it is important to read labels and ensure that these sweeteners do not contain any fillers or harmful ingredients.
