The ketogenic (keto) diet is a popular eating plan that focuses on high-fat, very low-carbohydrate intake to shift the body into a metabolic state called ketosis. This article explores the amount of sugar, or rather carbohydrates, you can consume while following a keto diet and provides guidance on how to make informed food choices.
Understanding the Keto Diet
The keto diet involves drastically reducing carbohydrate consumption and replacing it with fats. This restriction forces the body to burn fat for energy instead of glucose, leading to the production of ketones. This metabolic state is known as ketosis.
Macronutrient Ratios in Keto Diets
Different variations of the keto diet exist, each with varying macronutrient ratios:
- Standard Ketogenic Diet (SKD): This is the most researched version, consisting of 70% fat, 20% protein, and 10% carbohydrates.
- Cyclical Ketogenic Diet (CKD): This involves cycling between 5 days of low-carb intake and 2 days of high-carb intake.
- Targeted Ketogenic Diet (TKD): This allows for increased carbohydrate consumption around periods of high-intensity exercise.
- High-Protein Ketogenic Diet: This consists of 60% fat, 35% protein, and 5% carbohydrates.
Carbohydrate Limits on Keto
To maintain ketosis, a daily carbohydrate intake of up to 50 grams is generally recommended. Some individuals may need to restrict their carbohydrate consumption even further, while others might have slightly more leeway.
Net Carbs vs. Total Carbs
When following the keto diet, it's essential to focus on net carbs rather than total carbs. Net carbs represent the carbohydrates that the body can digest and absorb.

- Total Carbs: This includes all carbohydrates in a food serving, including fiber and sugar alcohols.
- Net Carbs: This is calculated by subtracting the amount of fiber and half the sugar alcohol content from the total carbohydrates.
Calculating Net Carbs
To calculate the net carbs in a food serving:
- Subtract the grams of fiber from the total grams of carbohydrates.
- If the food is processed and contains sugar alcohols, subtract half the grams of sugar alcohol from the result.
Sugar on Keto: Natural vs. Added
While the keto diet restricts overall carbohydrate intake, it doesn't necessarily eliminate sugar entirely. The focus is on choosing the right types of sugars and consuming them in moderation.
- Natural Sugars: These are found naturally in whole foods like fruits and dairy products. These options also include fiber, vitamins, minerals, and antioxidants.
- Added Sugars: These are introduced during food processing or preparation and are often found in processed foods, snacks, sauces, and sweetened beverages.
Identifying Hidden Sugars
Hidden sugars can easily sneak into your diet through processed foods, snacks, sauces, and salad dressings. To spot them, look for ingredients like fructose, sucrose, lactose, and dextrose - basically, anything ending with “-ose” might be a form of sugar.
Checking Nutrition Labels
Nutrition labels are your biggest ally. Always check the labels on packaged foods for the carbohydrate and sugar content.
Watch Out for Low-Fat Products
Many low-fat products have what's called a "health halo" effect. We view them as healthy, but to keep up the delicious, crave-worthy taste, manufacturers might add more sugar. Full-fat versions of foods are often more likely to be keto-friendly (and taste better, too).

Cut Back on Processed Foods
The more whole a food is, the less likely it will contain hidden sugar. The closer a food is to its natural state (e.g., an apple versus apple sauce versus apple pie), the healthier it will generally be.
Keto-Friendly Sweeteners
If you crave sweetness while following the keto diet, several keto-friendly natural sweeteners are available, like stevia, erythritol, and monk fruit. Many of these sweeteners are good for baking and for sweetening up your morning cup of coffee. Keep in mind, though, that baked goods and other treats can still contain carbohydrates and are fairly processed. While they might seem like healthier choices, check the ingredient list.
Foods to Enjoy on Keto
A wide variety of foods can be enjoyed on the keto diet while staying within your carbohydrate limits:
- Fresh Meat and Fish: These are staples of the keto diet, containing no carbs and providing essential nutrients. Examples include turkey, pork, chicken, lamb, beef, veal, venison, shellfish, tuna, cod, salmon, and sardines.
- Cheese: Most cheeses are low in carbs and high in fat, making them a good choice for keto.
- Low-Carb Vegetables: Green leafy vegetables (spinach, kale, lettuce), peppers, summer squash (zucchini), avocados, and olives are all excellent choices.
- Nuts and Seeds: Almonds, macadamia nuts, pecans, walnuts, chia seeds, and flaxseeds are high in fat and low in carbs.
- Berries: Berries like raspberries, blueberries, and strawberries can be enjoyed in moderation.
- Other Options: Eggs, plain Greek yogurt, cottage cheese, cream, half-and-half, unsweetened plant-based milk, shirataki noodles, dark chocolate (in moderation), olive oil, butter, ghee, unsweetened coffee and tea, and unsweetened sparkling water.
Foods to Limit or Avoid
Certain foods are high in carbs and should be limited or avoided on the keto diet:
- Wheat-Based Products: Rice, pasta, cereals, bread, and other grain-based products.
- Starchy Vegetables: Potatoes, corn, and other starchy vegetables.
- High-Sugar Fruits: Some fruits are high in carbs, so research - including checking labels - is key.
- Beans and Legumes: These are generally high in carbohydrates.
- Sugary Drinks: Sodas, juices, and sweetened beverages.
Potential Benefits of Reducing Sugar Intake
Cutting your sugar intake, even if you’re simply following a low-calorie or low-carbohydrate diet, has plenty of benefits. In a keto diet, it’s a must. Fortunately, there are quite a few benefits to cutting back (or cutting out) sugar.

- Improved Weight Management: Sugar is linked to weight gain. Cutting back on sugar will almost certainly result in weight loss.
- Better Blood Sugar: If you are managing conditions like diabetes, then reducing sugar intake can help you feel good and keep your blood glucose levels consistent.
- Lower Risk of Heart Disease: Sugar is linked to an increased risk of heart disease. If you want to improve cardiovascular health, ditch the sweets.
- Enhanced Dental Health: Your dentist wasn’t lying to you. Sugar plays a big role in tooth decay. Less sugar improves dental health and lowers your risk of cavities.
- Lower Risk of Certain Types of Cancer: While studies are still looking at the connection between high-sugar diets, inflammation, and cancer, there appears to be a correlation.
- Boosting Energy Levels: You’d think that sugar would give you more energy (and it does at first), but if your energy levels are unstable, cutting sugar can help you stabilize and keep your energy levels more evenly paced.
Tips for Staying on Track
- Read Nutrition Labels: At the beginning of keto, nutrition labels are your biggest ally. Always check the labels on packaged foods for the carbohydrate and sugar content.
- Track Your Macros: Measure your foods and write down your carb intake, especially at first.
- Enjoy Whole, Unprocessed Foods: Choose foods as close to their natural state as possible.
- Modify Recipes: If you crave carbohydrates and sugar-heavy foods, consider ways to modify the recipe in a keto-friendly way.
- Don't Deprive Yourself: The more you tell yourself that you can't have something, the more it feels like punishment.
- Consider your cravings conquered! If you’re ready to beat sugar cravings and stay within your sugar grams (while still staying full and satisfied), It’s Skinny is a delicious answer. The less you feel punished and deprived, the more likely you will be to stick to your guns and make progress on keto!
Potential Side Effects and Risks
The ketogenic diet may cause side effects, especially when starting. These can include the "keto flu," characterized by fatigue, headache, and digestive issues. Long-term risks may include kidney stones, osteoporosis, and nutrient deficiencies if the diet is not well-planned.
Consulting with a Healthcare Professional
It's essential to consult with a doctor or registered dietitian before making significant dietary changes, especially if you have underlying health conditions like diabetes. Regular health monitoring is important to check for any adverse effects.
