Sweet onions contain 6.65g net carbs per 100g
Onions are not completely keto-friendly due to their carbohydrate content. However, they can be consumed in moderation as part of a ketogenic diet. The key is to be mindful of the carbohydrate count and choose onion varieties with lower carb counts, such as green onions or scallions, which can be used in recipes without sacrificing flavour.
Sweet onions, in particular, have a higher carbohydrate content than some other varieties. They contain 6.65g of net carbs per 100g. In comparison, yellow onions contain 5.9g, white onions contain 6.48g, and red onions contain 5.96g of net carbs per 100g. Therefore, if you are aiming to limit your carb consumption, it may be advisable to swap out sweet onions for yellow or white onions in your recipes.
It is worth noting that the average person on a ketogenic diet can consume around 20-25g of net carbs per day. A 100g serving of onions, regardless of variety, contributes significantly to this daily allowance. Therefore, it is recommended to consume onions in small quantities, such as ¼ to ⅓ cup servings, to stay within the desired carb limit.
Additionally, it is important to consider individual health needs when including onions in your diet. Onions are high-FODMAP foods and can be triggering for individuals with IBS, Chron's disease, or other digestive issues.

Red onions are less keto-friendly due to their higher sugar content
Onions can be consumed on a keto diet, but only in moderation. While onions are a good source of vitamins, minerals, and antioxidants, they are also high in carbohydrates. Red onions, in particular, have a higher sugar content than other varieties of onions, making them less keto-friendly.
Red onions have a strong flavour and a peppery punch. They are commonly used for grilling, pickling, or garnishing salads. A 100g serving of red onions contains 5.96g of net carbs, which is slightly higher than the net carb content of other onion varieties. For example, sweet onions contain 6.65g of net carbs per 100g, while yellow onions contain 5.9g, and white onions contain 6.48g.
Since red onions have a higher sugar content, they should be used sparingly in recipes. If a recipe calls for red onions, it is recommended to use a keto-friendly substitute such as green onions or scallions, which have a lower carb count of 4.7g net carbs per 100 grams. However, it is important to note that all onions can be included in a keto diet in small amounts, as long as carbohydrate consumption is tracked to avoid exceeding daily carb limits.
While on a keto diet, it is recommended to limit carbohydrate consumption to 20-25g of net carbs per day. A 100g serving of onions, regardless of variety, is over a quarter of the total daily recommended carb intake.

This is especially true for those in the early stages of ketosis, as even a small amount of onions can impact carbohydrate levels.
