                                According to the USDA, a 100g serving of raw onion contains an average of 7.6 grams of net carbs, a significant amount that could impact a ketogenic diet's strict carb limits. This high carb load is a primary reason why avoid onions on keto, or at least restrict their quantity, to maintain a state of ketosis.
