How many grams of sugar can you have on Keto

A ketogenic or keto diet is a high-fat, low-carb diet designed to help with weight loss by putting your body into a metabolic state known as ketosis. While on this diet, the primary energy source switches from glucose (from carbs) to ketones (from fats). This shift can aid in weight loss, improve insulin sensitivity, and bring several other health benefits.

Given the low-carb nature of the ketogenic diet, it’s understandable why people get confused about their sugar intake. After all, sugar is a type of carbohydrate.

Sugar on a Keto Diet

Sugar, whether it's table sugar, brown sugar, or high-fructose corn syrup, is a simple sugar that can rapidly spike your blood glucose levels, leading to an insulin surge. The American Heart Association suggests limiting added sugars due to their link to weight gain and risk factors such as high blood pressure and risk of heart disease.

On a keto diet, your daily carb limit is typically about 20-50 grams of net carbs. Now, you might ask, "how does sugar fit into my carb intake?" The answer is, "it’s complicated." You see, sugars are considered total carbohydrates. This means, in theory, you could use part of your daily carb allowance for sugar. However, doing so would contradict the core principle of the ketogenic diet – minimizing high glycemic index carbs to maintain a state of ketosis.

Natural sugars, such as those in fruit juices and some dairy products, also fall into the total carbohydrates count. It's not a good idea to have a lot of sugar, whether natural or added, on a ketogenic diet as it can disrupt the metabolic state that makes the diet so effective.

Tips for Managing Sugar Intake on Keto

Read the Nutrition Label

Reading the nutrition label is more than a good idea; it's an essential habit for those on a ketogenic diet. Food labels give you a comprehensive understanding of what you're about to consume. They reveal not only the grams of sugar but also the grams of total carbs, grams of fiber, and other key nutritional information.

For keto dieters, it's not just about counting the grams of sugar. You have to focus on 'net carbs,' a concept which considers the grams of total carbs minus the grams of fiber. This is crucial because dietary fiber is a type of carbohydrate that your body can't digest, so it doesn't impact your blood sugar levels and won't interrupt ketosis.

Opt for Natural Sweeteners

In a world where sugar is in almost everything, keto-friendly sweeteners are a lifesaver. Natural options like Stevia, Erythritol, and Monk Fruit sweetener are excellent because they have little to no impact on blood sugar levels. These alternative sweeteners are low on the glycemic index, meaning they don't cause a rapid spike in blood glucose levels like regular sugar does.

In addition to being keto-friendly, these sweeteners come with their own unique benefits. Stevia, for instance, is calorie-free and has been linked to lower blood pressure. Monk Fruit Sweetener has antioxidant properties, and Erythritol doesn't cause tooth decay like traditional sugar.

Find Low-Carb Alternatives

For those moments when you're hit with sugar cravings, remember that there are always keto alternatives. You'd be surprised at the number of low-carb snacks that can satiate your sweet tooth. From keto-friendly chocolate to low-carb pastries made with almond or coconut flour, you have options.

When picking out low-carb alternatives, pay close attention to food labels. Look for products that use natural sweeteners and have a low number of carbs. With these snacks, you can enjoy a sweet treat without worrying about going over your daily carb limit or disrupting your state of ketosis.

Incorporate Healthy Fats

Healthy fats are the backbone of the ketogenic diet. Foods rich in healthy fats like olive oil, coconut oil, avocados, and fatty fish not only increase the satiety of your meals but also help curb sugar cravings. This is because fats take longer to digest, making you feel fuller for longer.

Moreover, these fats don't cause a spike in your blood glucose levels like sugar does. So, incorporating them into your meals can help keep your energy levels stable and reduce the instances of sugar cravings. These fats also offer numerous health benefits, such as improved heart health, enhanced brain function, and better weight management.

Maintaining a low-sugar lifestyle on keto may seem challenging initially. But with a keen eye on your food's nutrition facts, opting for natural sweeteners, finding low-carb alternatives to your favorite sugary foods, and incorporating more healthy fats into your meals, you can manage your sugar intake effectively while still enjoying the foods you love.

H ow many grams of sugar can you have on keto FAQ

Q: Can I consume sugar alcohols on a keto diet?

Q: Are all sugars the same in a keto diet?

A: Not all sugars are created equal. While table sugar, brown sugar, and white sugar are high in carbs, some sugars, like those in dairy, come with other essential nutrients like protein and Vitamin C.

A: Consuming too much sugar can indeed disrupt your state of ketosis, as it increases your blood sugar and insulin levels.


In conclusion, the amount of sugar you can have on keto is minimal. Sugar consumption needs to be carefully managed to maintain ketosis and promote metabolic health. The key is to keep track of your grams of carbs, read nutrition labels, opt for natural sweeteners, and find low-carb alternatives to your favorite sweet treats.

While it might seem tough at first, sticking to these rules can help not only in successful weight loss but also in overall health improvement.
