The ketogenic diet, or keto diet, is a low-carb, high-fat diet that promotes weight loss and has been shown to provide numerous health benefits. To follow the keto diet, it is important to know how to read nutrition labels on packaged foods. Nutrition labels can be tricky to understand, but they provide valuable information about the food we eat and can help us make the right diet choices. The main goal of the keto diet is to shift the body into ketosis, a metabolic state in which the body uses fat for energy instead of carbohydrates. This is achieved by consuming a very low amount of carbohydrates and replacing them with fat. The nutrition facts label on packaged foods can help individuals on the keto diet understand the amount of carbohydrates, protein, and fat in a serving, as well as other important nutritional information.
| Characteristics | Values |
|---|---|
| Carbohydrates | Check the total carbohydrates and calculate net carbs by subtracting dietary fiber and sugar alcohols. |
| Fats | Check the grams of fat and be mindful of saturated fats, which can be unhealthy in large quantities. |
| Proteins | Ensure sufficient protein intake, which helps you feel full for longer. |
| Sugar | Avoid added sugars and syrups. Sugar alcohols like erythritol can be a suitable alternative. |
| Serving Size | Pay attention to the serving size and the number of servings per container. Smaller serving sizes may be used to manipulate the nutrition facts. |
| Macronutrients | Calculate the percentage of each macronutrient (carbs, fats, proteins) to ensure they align with your daily keto goals. |
| Calories | Consider the calorie count per serving and how it fits within your daily energy intake. |
| Micronutrients | Look for foods high in Vitamin D, dietary fiber, calcium, potassium, and iron to support overall health. |
| Whole Foods | Choose whole, unprocessed foods like vegetables, fruits, healthy fats, nuts, and seeds whenever possible. |

What You'll Learn
Understanding nutrition labels
Serving Size and Servings per Container
The nutrition label always mentions the serving size and the number of servings per container or package. It's important to note that the serving size is a standardised measure and may not reflect the amount you typically consume. Always check the serving size and be mindful of your portion sizes.
Macronutrients: Carbohydrates, Protein, and Fat
The main portion of the nutrition label includes essential macronutrients like carbohydrates, protein, and fat. The ketogenic diet is a low-carb, high-fat diet, so you should pay close attention to these values. Check the total carbohydrates and calculate the net carbs by subtracting dietary fibre and sugar alcohols. Be cautious of hidden sugars, as they can affect your carb count.
Added Sugars, Saturated Fats, and Sodium
Typically, added sugars, saturated fats, and sodium are overconsumed and can lead to health issues like cardiovascular disease. It's best to limit or avoid these nutrients. Added sugars are usually derived from artificial sweeteners, so look out for ingredients like corn syrup or sugar.
Daily Value
The nutrition label will also provide the percent daily value of various nutrients. Generally, 5% or below is considered low, while 20% or more is considered high. Aim for foods high in vitamin D, dietary fibre, calcium, potassium, and iron.
Ingredients List
In addition to the nutrition label, always check the ingredients list. Look for obvious ingredients to avoid on a keto diet, such as flour, starch, syrups, oats or grains, and sugar. Remember that sugar can be listed under different names or included as natural sugars.
Calories
The nutrition label will also display the number of calories per serving. Fatty foods consumed on a keto diet can be calorie-dense, so be mindful of your calorie intake.
Remember that whole, unprocessed foods are always the best option, even on a keto diet. Nutrition labels can be tricky, so it's important to practice reading them and calculating your macros to stay on track with your keto goals.

Checking grams of fat, carbs, and fiber
Checking the grams of fat, carbs, and fiber is crucial when following a ketogenic diet. Here's a detailed guide to help you navigate this process effectively:
Understanding Macronutrients:
The keto diet revolves around achieving a state of ketosis, which is maintained by balancing your intake of macronutrients: fat, carbohydrates, and protein. Each of these macronutrients provides a certain amount of calories per gram, and they collectively influence weight loss, maintenance, or gain. While calorie counting is less emphasized in keto, understanding the calorie content of these macronutrients is still valuable.
Reading Nutrition Labels:
When checking nutrition labels, start by looking at the total carbohydrates. This value includes sugar, starch, and fiber. To calculate the net carbs, subtract the grams of dietary fiber and sugar alcohols from the total carbohydrates. Net carbs are crucial in keto, as the diet typically restricts carb intake to 5% or less of total calories. Remember to pay attention to the serving size to ensure you don't exceed your daily carb limit.
Identifying Sugar Content:
Sugar is often a hidden culprit in packaged foods. Check the grams of sugar listed under total carbohydrates. The "sugars" value includes both naturally occurring sugars (like fructose in fruits) and added sugars (such as in salad dressings or baked goods). Be cautious of serving sizes that seem unusually small, as they may be manipulating the nutrition facts to appear healthier.
Evaluating Fat Content:
When checking grams of fat, differentiate between unsaturated fats, which are considered healthier, and saturated and trans fats, which should be limited. The total fat content on a label includes all types of fats. Additionally, be mindful of sodium content, as it's often linked to fat intake and can impact cardiovascular health.
Fiber Considerations:
Fiber is an essential part of a healthy diet, promoting good gut health. While it's included in the total carbohydrate calculation, it doesn't negatively impact ketosis. Therefore, many people on the keto diet calculate net carbs to ensure they're not reducing their fiber intake too drastically.
Remember, the keto diet is not just about macronutrient ratios but also about the quality of those macronutrients. Aim for healthy fats and complex carbs while limiting added sugars and processed foods.

Calculating net carbs
Counting net carbs is a must for many keto dieters. Net carbs refer to the amount of carbohydrates your body digests and uses for energy. This is different from total carbohydrates, which include dietary fibre and sugar alcohols that the body cannot break down and absorb. By only counting net carbs, keto dieters get a truer sense of how many carbs their body is using for energy, which is key to staying in ketosis.
To calculate net carbs, take a food's total carbohydrates and subtract the grams of dietary fibre and sugar alcohols. This can be done using the following formula:
Net carbs = Total carbs – dietary fibre – sugar alcohols
It is important to note that not all sugar alcohols are truly carb-free. Some sugar alcohols can kick you out of ketosis due to their high glycemic load. Additionally, manufacturers may manipulate nutrition labels by using small serving sizes to make their products appear lower in carbohydrates. Therefore, it is crucial to examine the ingredients and look for obvious keto no-nos like flour, starch, syrups, oats/grains, and sugar.
When reading nutrition labels, pay attention to the percentage of each macronutrient (carbs, protein, and fat) the food item will contribute to your daily intake. For example, if your daily allotment is 20 grams of net carbs, a food item with 15 grams of net carbs would not be a good option as it would use up three-quarters of your daily carb count. To stay within your macros, follow the one-third rule: never eat more than one-third of your daily carbs in one sitting.

Identifying ingredients to avoid
When following a ketogenic diet, it is important to be able to identify ingredients that you should avoid. The keto diet is a low-carb, high-fat diet that involves shifting your body into ketosis, a metabolic state in which your body uses fat for energy instead of carbohydrates. To do this, you need to consume the right ratio of carbs, fats, and proteins.
The nutrition facts label on packaged foods is a valuable source of information for anyone on a keto diet. It tells you the amount of carbohydrates, protein, and fat in a serving, as well as other important nutritional information. The main portion of the label includes all essential nutrients like fat, carbohydrates, and proteins.
- Check the grams of sugar on the nutrition facts label. This includes both naturally occurring sugars (like fructose in lemon juice) and added sugars (like sugar or corn syrup in some salad dressings). The newly updated nutrition facts label distinguishes between these two types of sugars, but some smaller companies may not have adopted this yet.
- Be mindful of sweeteners, including some sugar-free sugar alcohols, as these can affect your overall carb count. Erythritol, a sugar-alcohol, is acceptable on the keto diet as long as you do not have adverse reactions to it.
- Avoid ultra-processed foods, which are high in additives and low in nutrients. Instead, focus on eating whole, unprocessed foods like vegetables, fruits, healthy fats, nuts, and seeds.
- When choosing fatty foods, remember that a little goes a long way. Most fatty foods that are suitable for a keto diet are calorie-dense, so be mindful of serving sizes.
- Calculate the net carbs of a product by subtracting the grams of dietary fiber and sugar alcohols from the total carbohydrates. This can be a great way to compare similar products.
- Look at the percentage of each of your macros that a food item will take up. For example, if you are allotted 20 grams of net carbs per day, a food item with 15 grams of net carbs would not be a good option as it would use up three-quarters of your daily carb allowance.
By following these tips and carefully reading nutrition labels, you can successfully identify ingredients to avoid when following a ketogenic diet.

Comparing products
When comparing products for a ketogenic diet, it is important to remember that the diet is very low in carbohydrates, high in fat, and moderate in protein. Carbohydrates are the body's preferred source of energy, but on a strict ketogenic diet, only 5% to 10% of energy intake comes from carbohydrates. This reduction in carbohydrates puts the body into a metabolic state called ketosis, where it starts breaking down stored fat into molecules called ketone bodies to use for energy.
When comparing products, look at their Nutrition Facts labels, where food manufacturers must list the grams of carbohydrates. Each gram of carbohydrate provides 4 calories of energy. Focus on choosing nutrient-dense carbohydrates, such as non-starchy and starchy vegetables, legumes, whole grains, and fibrous fruits. Educate yourself on portion sizes and the value of fiber. Limit refined carbohydrates, beverages, and foods with added sugar. Instead, opt for carbohydrate calories from fibrous vegetables and whole grains.
Some foods to include in your ketogenic diet are meat, fish, eggs, butter, nuts, healthy oils, and avocados. Fish is rich in B vitamins, potassium, and selenium, as well as protein and omega-3 fats. Avocados are high in monounsaturated fat and potassium. Greek yogurt and cottage cheese are also high in protein and calcium.
Some foods to avoid are all grains and flour products, added and natural sugars in food and beverages, starchy vegetables like potatoes, corn, and squash, fruit juices, and legumes. Most ketogenic plans allow foods high in saturated fat, such as fatty cuts of meat, processed meats, lard, and butter. However, an emphasis on foods high in saturated fat goes against recommendations from the Dietary Guidelines for Americans and the American Heart Association and may adversely affect blood LDL cholesterol. It is possible to modify the diet to emphasize foods low in saturated fat, such as olive oil, avocado, nuts, seeds, and fatty fish.
Remember, the perfect approach to keto may differ from person to person, and it is always good to consult a doctor or a dietitian before starting a new diet.
