How Much Sugar Can You Have On The Keto Diet

The ketogenic diet, or keto diet, has gained significant popularity in recent years due to its potential for weight loss and improved health markers. This low-carb, high-fat diet aims to put the body into a state of ketosis, where it burns fat for fuel instead of carbohydrates. While the focus of the keto diet is on reducing carbohydrate intake, it is essential to understand how sugar fits into this dietary approach.

The Basics of the Keto Diet

The keto diet involves drastically reducing carbohydrate intake and replacing it with fat. By doing so, the body enters a metabolic state called ketosis, where it becomes efficient at burning fat for energy. This shift in metabolism can lead to weight loss and other health benefits.

On the keto diet, the typical macronutrient breakdown is as follows:

  • 70-75% of calories from fat
  • 20-25% of calories from protein
  • 5-10% of calories from carbohydrates

The Role of Sugar on the Keto Diet

Sugar is a type of carbohydrate, and on the keto diet, carbohydrate intake is significantly restricted. The goal is to minimize blood sugar spikes and insulin release, as these can inhibit ketosis and fat burning. Therefore, it is crucial to limit sugar consumption while following the keto diet.

When it comes to sugar on the keto diet, it is important to differentiate between natural sugars found in whole foods and added sugars found in processed foods. Natural sugars, such as those found in fruits and vegetables, come packaged with fiber and other nutrients that slow down their absorption and minimize their impact on blood sugar levels. However, added sugars, such as those found in sugary beverages and desserts, can quickly spike blood sugar levels and hinder ketosis.

How Much Sugar Can You Have on the Keto Diet?

While there is no specific limit on sugar intake for the keto diet, it is generally recommended to keep total carbohydrate intake below 50 grams per day. This includes both natural and added sugars. However, it is important to note that individual carbohydrate tolerance may vary, and some people may need to consume fewer carbohydrates to achieve and maintain ketosis.

When it comes to sugar, it is best to prioritize natural sources such as low-sugar fruits like berries and avocados. These fruits provide essential vitamins, minerals, and fiber while keeping sugar intake relatively low. It is also important to read food labels carefully and avoid foods with added sugars, such as sugary snacks, sodas, and processed foods.


1. Can I consume artificial sweeteners on the keto diet?

Artificial sweeteners, such as stevia, erythritol, and monk fruit extract, are generally considered keto-friendly as they do not significantly impact blood sugar levels. However, it is important to use them in moderation and be mindful of any potential digestive issues they may cause.

2. What are the risks of consuming too much sugar on the keto diet?

Consuming too much sugar, especially added sugars, can lead to blood sugar spikes, hinder ketosis, and contribute to weight gain. It can also increase the risk of developing chronic conditions such as type 2 diabetes and heart disease.

3. Can I have cheat days with high sugar intake while on the keto diet?

Cheat days with high sugar intake can significantly disrupt ketosis and hinder progress on the keto diet. It is best to avoid cheat days or opt for keto-friendly alternatives to satisfy cravings.

4. Are there any natural sweeteners that are keto-friendly?

Yes, there are several natural sweeteners that are considered keto-friendly, including stevia, erythritol, monk fruit extract, and small amounts of raw honey or maple syrup. However, it is important to use them in moderation and consider their impact on blood sugar levels.

5. Can I consume fruits on the keto diet?

While fruits contain natural sugars, some low-sugar fruits like berries and avocados can be consumed in moderation on the keto diet. These fruits provide essential nutrients while keeping carbohydrate intake relatively low.

6. How can I satisfy my sweet tooth on the keto diet?

There are several keto-friendly alternatives to satisfy a sweet tooth, including sugar-free desserts made with natural sweeteners, dark chocolate with a high percentage of cocoa, and keto-friendly fruit options like berries.


The keto diet focuses on reducing carbohydrate intake to promote ketosis and fat burning. While there is no specific limit on sugar intake, it is crucial to minimize both natural and added sugars to maintain ketosis and achieve optimal results. Prioritizing low-sugar fruits and avoiding processed foods with added sugars is key to successfully following the keto diet. Additionally, incorporating keto-friendly sweeteners and alternatives can help satisfy cravings while staying on track.
