Carbohydrate tolerance varies among individuals. Some people may need to limit themselves to no more than 30 grams of total carbohydrates per day to remain in nutritional ketosis and maintain its benefits; while others may be able to consume more. However, most people with underlying metabolic issues find that they need to maintain a carbohydrate intake below 50 grams per day, especially if they have type 2 diabetes. With diabetes reversal and weight loss over time, many people’s insulin sensitivity improves, and this can open the door to increased carbohydrate tolerance. Thus, to remain in sustained nutritional ketosis you may want to initially consume closer to 30 grams per day; and then while tracking fingerstick blood ketones (the urine test is undependable) explore your personal level of carbohydrate tolerance while maintaining your metabolic health.
