Sushi rolls, or maki rolls, contain a lot of white rice which fills them up with calories and carbs, leaving little room for any other important nutrients like protein or fiber. How many carbs are in your sushi rolls really depends on their size and how much white rice it contains.  However, on average, a sushi roll contains 3 or 4 ounces of white rice. This means that the average sushi roll contains 30 grams of carbs - that’s around 140 calories!  This means that most sushi rolls are not keto-friendly because they are so high in carbs!
