Keto And Sugar: Enemies Or Frenemies?

The keto diet is a low-carb, high-fat diet that can lead to reductions in blood sugar and insulin levels, as well as weight loss. When following a keto diet, it is important to limit sugar intake as much as possible because sugar is a carbohydrate, and consuming carbohydrates can kick your body out of ketosis. Ketosis is a condition in which the body burns fat instead of carbohydrates for energy. While it is not necessary to completely eliminate sugar from your diet, it is recommended to limit it to 20-30 grams of carbohydrates per day. This includes not only refined sugar but also natural sweeteners like honey and maple syrup, as well as fruits high in carbohydrates such as bananas, apples, and oranges. Even small amounts of sugar can impact blood sugar and insulin levels, so it is important to be mindful of your sugar intake when following a keto diet.

Sugar is a carbohydrate, and the keto diet recommends limiting your daily carb intake to 20-30 grams

Sugar is 100% carbs, and all sugars have a similar negative impact on weight gain, blood glucose, and insulin response. Therefore, on a keto diet, sugar in all its forms should be avoided. This includes sweeteners such as white or brown sugar, maple syrup, coconut sugar, and dates, which have the same effect on blood sugar, weight, and insulin resistance as pure white sugar.

However, it is important to distinguish between naturally occurring sugars and added sugars. Naturally occurring sugars, such as those found in fruit (fructose) and milk products (lactose), are not inherently bad and can be included in a keto diet in moderation. For example, a cup of blackberries has 13.8 grams of carbohydrates, but when you subtract the fibre grams, you are left with only net carbs, which is acceptable on a keto diet. Similarly, dairy products like milk and cheese contain naturally occurring sugars, with milk being higher in lactose and carbs, and cheese being a lower-sugar option.

Added sugars, on the other hand, should be kept to a minimum on a keto diet. These are sugars that are added to processed foods and can include cane juice, corn syrup, granulated white sugar, and high-fructose corn syrup. While you can include small amounts of added sugars in your daily macros, they can quickly use up your carbohydrate allowance and kick your body out of ketosis.

So, while you don't have to quit sugar entirely on a keto diet, it is important to be strategic about the types and amounts of sugar you consume.

Sugar can quickly use up your daily carb allowance and kick your body out of ketosis

Sugar and Ketosis: Enemies or Occasional Friends?

When your body is deprived of carbohydrates, it enters a state called ketosis, where it burns fat for energy instead of carbohydrates. This process can take several days, and maintaining it requires a strict low-carb diet.

Sugar is a simple carbohydrate that can quickly use up your daily carbohydrate allowance and kick your body out of ketosis. A single tablespoon of sugar contains 12.5 grams of carbohydrates, and a tablespoon of honey contains 17 grams.

To illustrate, the recommended daily carbohydrate intake for keto is 20 to 50 grams. A Hershey's milk chocolate bar has 25 grams of net carbs, which is already close to or exceeds the daily limit.

The Problem with Sugar and Ketosis

The issue with sugar on keto is that they are incompatible. If you consume enough sugar, your body will switch back to using glucose (from carbohydrates) as fuel, kicking you out of ketosis.

So, How Much Sugar Will Kick You Out of Ketosis?

The recommended daily sugar intake on keto is zero grams to avoid spiking blood sugar and insulin levels. However, you can still have small amounts of sugar if you budget it into your daily macros.

Strategies for Handling Sugar Cravings on Keto

• Indulge in fruits with low carbs, such as berries.
• Opt for keto-friendly sweeteners like Stevia, Erythritol, or Monk Fruit.
• Enjoy a keto-friendly dessert or a few bites of a non-keto treat.
• Plan for a higher-carb meal and get back to keto at the next meal.

The Bottom Line

While sugar and ketosis don't mix well, the occasional treat won't derail your long-term keto goals. The key is moderation and being mindful of your daily carbohydrate allowance.

Sugar increases blood sugar and insulin levels, which can lead to insulin resistance and weight gain

Sugar is a combination of glucose and fructose, which are both carbohydrates. On a keto diet, it is recommended to consume 20 to 30 grams of carbohydrates per day. A single tablespoon of sugar contains 12.5 grams of carbohydrates, which can quickly use up your daily allowance and potentially kick your body out of ketosis.

When you consume sugar, your body breaks it down into glucose. This causes your blood sugar and insulin levels to rise. Insulin is a hormone that helps the body use or store glucose as energy. However, if you consume too much sugar, your body may become resistant to insulin, leading to a condition called insulin resistance. This means that the body's cells don't respond properly to insulin, making it harder for glucose to enter the cells, and as a result, blood sugar levels remain high.

Insulin resistance can lead to weight gain and increase the risk of developing type 2 diabetes. This is because when the body is unable to use glucose effectively, it gets stored as fat. Additionally, high blood sugar levels can also cause inflammation and increase the risk of nonalcoholic fatty liver disease.

Therefore, it is important to limit sugar intake on a keto diet to maintain ketosis and avoid the negative health effects associated with high blood sugar and insulin levels.

Sugar alternatives, like artificial sweeteners, can also impact blood sugar and insulin levels

Sugar Alternatives and Insulin Levels

Sugar alternatives, such as artificial sweeteners, can be used to satisfy a sweet tooth while on a keto diet. However, it is important to note that these alternatives can still impact blood sugar and insulin levels. The key is to choose sweeteners that have a low glycemic index (GI) and do not cause a significant increase in blood sugar or insulin levels.

Artificial sweeteners like sucralose, maltodextrin, dextrose, aspartame, and Splenda are popular choices. Sucralose, for example, is derived from cane sugar that has been modified with chlorine atoms, making it over 600 times sweeter than cane sugar. While it has a low GI and does not affect blood sugar, it can trigger intense sugar cravings and lead to weight gain. Maltodextrin, a common filler in packaged foods, has a high GI and can impact blood sugar levels. Dextrose, a simple sugar found in honey and refined sugar, also ranks high on the GI and should be consumed with caution. Aspartame, found in diet sodas, is about 200 times sweeter than sucrose and can trick the body into thinking it has consumed more sugar, leading to increased cravings. Splenda, which contains sucralose, also has thickening agents like maltodextrin and dextrose that will impact blood sugar and insulin levels.

Natural sweeteners like stevia and monk fruit are other alternatives. Stevia is derived from an herb and is 250 to 300 times sweeter than sucrose. It has zero calories, no sugars, and no carbs, and it can help lower blood sugar and insulin levels. However, it may cause digestive issues for some people. Monk fruit sweetener is also natural and has no sugar, no carbs, and no calories. It has anti-inflammatory and anti-obesity properties and can help fight fungal infections. It is important to check labels when purchasing monk fruit products to avoid added ingredients like maltodextrin and dextrose.

While sugar alternatives can be a helpful way to satisfy sweet cravings while on a keto diet, it is important to choose options that have a low impact on blood sugar and insulin levels. Additionally, it is crucial to consume these alternatives in moderation, as they can still trigger cravings and impact overall health.

Excessive sugar consumption is linked to harmful health conditions, including chronic inflammation, obesity, and dental issues

Why You Should Avoid Sugar on a Keto Diet

Chronic Inflammation

Chronic inflammation is a harmful health condition associated with excessive sugar consumption. Inflammation is the body's natural response to injury or infection, but when it becomes chronic, it can lead to long-term damage. Sugar, especially in high amounts, can trigger and worsen inflammatory processes in the body. This is because sugar can cause spikes in blood sugar and insulin levels, leading to increased inflammation. By reducing sugar intake on a keto diet, you can help mitigate these inflammatory responses and lower your risk of developing chronic inflammatory conditions.

Obesity and Metabolic Syndrome

Obesity and metabolic syndrome are also linked to high sugar consumption. Sugar is often associated with weight gain and can lead to obesity if consumed in excess. This is because sugar is high in calories and easily added to various foods and beverages, increasing overall calorie intake. Additionally, sugar can affect hormones that regulate hunger and fullness, leading to overeating and weight gain. Metabolic syndrome, a cluster of conditions including increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol levels, is also associated with high sugar intake. By reducing sugar on a keto diet, you can support weight management and lower your risk of developing metabolic syndrome.

Dental Issues

Dental issues, such as dental plaque and cavities, are common consequences of excessive sugar consumption. Sugar, especially in the form of added sugars, can promote the growth of harmful bacteria in the mouth, leading to plaque formation and tooth decay. The bacteria feed on the sugars, producing acids that erode tooth enamel and increase the risk of cavities. By reducing sugar intake, you can improve your dental health and lower the risk of dental issues.

In summary, excessive sugar consumption is linked to various harmful health conditions, including chronic inflammation, obesity, and dental issues. When following a keto diet, it is important to minimize sugar intake to promote overall health and well-being. While it may be challenging to cut back on sugar, the potential health benefits make it a worthwhile endeavor.
