I don't know what you're talking about...those of us who eat low-carb DO NOT try to get into "starvation mode". Unless you are talking about ketosis, but that isn't starvation by any means. All "starvation mode" is going to get you is fatter because you can't sustain that very long, and then you'll binge, and you'll be back where you started and then some.
Buy yourself a few good books on low-carb eating, read them, and then come back and ask all the questions you want about hints/help/support for this way of life.
