I always stay around 50-60 g total carbs and <42 g NC carbs a day and do well there. Everyone's different. You won't starve if you eat enough fat and protein foods (ideally in combination) to feel full. Atkins wasn't designed for starvation although in the beginning it may take a while for you to get a handle on what, how much and how often you eat to find your ideal levels and routines.
