Ok, there was a misunderstanding of some sort, then.
However, people do lose weight, and improve body composition by going low-carb.
It depends on your lifestyle. If you are moderately active, then you need about 60-65g of carbs per meal. And you need to eat 3 times a day. If you are less active, cut back 10g or so. If you think you are going to loose weight by eating a nice green salad for lunch, you are wrong. Why? Because you don't have any carbs in a salad. And if your other 2 meals are carb deprived, your body will produce the glucose you need, and it ALWAYS produces more than you need. (hopefully using body instead of chemical secreting liver will prevent further techical discussion) That excess however is stored as FAT. Abdominal fat. Not leg fat, underarm fat, abdominal fat.
