If you are on diet and you like sushi, you are in luck. Sushi helps you maintain your healty diet, but beware! Not all sushi are low in calory. When it comes to choosing low cal sushi, all you do is excercise your common sense. Anything cooked including tempura and spider rolls are high in calory because… you guessed it. An oil is used in the process of making them. Go for the sushi with fresh ingredient, but stay away from those with mayo. Again, no brainer.
