A daily limit of 60 to 130 grams of carbohydrates is typical with a low-carb diet. These amounts of carbohydrates provide 240 to 520 calories. Some low-carb diets greatly restrict carbs during the initial phase of the diet and then gradually increase the number of allowed carbs.
I do a lot of reading about low carb/kenogenic diets, and typically I see people are in ketosis and losing weight between 20-60 net grams of carbs a day. I began my low carb (not low enough for some people) with a goal of <100 net grams a day, and I've lost about 2 lbs a week.
