If you are eating too much, you are not going to lose weight no matter how low your carbs are. Dr Eades had a post on this today: Low carb and calories
Although the lowered insulin and elevated glucagon open the doors to the fat cells allowing fat to come out to be burned, the fat comes out only if it’s needed. If you are meeting all your body’s energy needs with the food you eat, the body doesn’t need the fat in the fat cells. On a low-carb diet your body burns fat for energy. But it doesn’t care where this fat comes from; it can come from the diet or it can come from the fat cells or it can come from both. If you are consuming enough fat to meet all your body’s requirements, your body won’t go after the fat in the fat cells no matter how severely you restrict your carbs. You will burn dietary fat only and no body fat. And you won’t lose weight. It’s that simple.
The low-carb diet is a wonderful, healthful way to lose weight quickly, but you do have to watch your calories as well to a certain extent. If your plugging along losing away, keep doing what you’re doing. But if you quit losing, take a look at your cheese and/or nut consumption. Cut those out, and I’ll just about guarantee that your weight loss will pick up again.
