Tons of people have lost weight by following a carb-free routine such as the Atkins Diet, which promotes eating mostly protein and avoiding carbs. The problem is that as soon as you go back to your regular, carb-full diet, you'll most likely gain the weight back.
Aside from the fact that a carb-free diet is not sustainable in the long-term, there are many healthy foods high in carbs — such as fruit and whole grains — that offer valuable and essential vitamins, not to mention filling fiber, that you'll be missing out on. It's also tough to avoid bread, pasta, and cookies entirely, so denying yourself will only make you crave them more. Instead, find a balanced diet that you can live with forever; it's your best bet for losing weight and keeping it off.
