I don't think you could eat too much raw spinach. My Atking Carb Counter lists it as .2g net carbs for 1/2 cup. If you had five cups that would only be one whole net carb. I eat a lot of spinach in my salad, as well as different kinds of lettuce, scallions, red cabbage, cucumber, and even tomatoe. You can have all these things on induction. Just measure and count the carbs, and stay under 20.
