Yeah the key to losing your stomach is cardio (running, etc) to lose the excess fat, and abs work to tone up the stomach muscles. Getting in the habit of sucking it in(good posture) also helps. If you work in an office spend a few minutes each day sucking in as much as you can, holding it for 10 seconds, and letting it out. Do it a few times. Changing your diet isn't going to help. I've seen bony girls with a tummy. Salad and a water please. Boo that. Atkins is an awful diet. People who are on it don't realize the controversy behind it. Carbs are an important part of your diet and if you take them away you can never bring them back unless you're willing to put on many many lbs. Reduce your carb intake at night though and track it through out the day like fat. But like i said, diet is no substitute for exercise especially since exercise makes you feel better and you benefit from it for the rest of your life. Body and Mind. Edit: From what I've heard, when you lose the carbs your body has to get what it loses from your body fat and that's how you lose weight. But after the fat is gone, your body has no source for these nutrients. I consider it an unhealthy way to lose weight.
