IMHO its time to look at another strategy or lc plan.

Some ideas.

Women over 40 sometimes need to do a lower fat, 30-40% plan.

Are you getting at least 12 ounces cooked weight protein a day?

Do you know your metabolic type? People are one of three types protein, carbo or mixed. Protein types do best on Atkins. If you are a carbo or mixed type you might do best on the Cabbage Soup Diet, Somersizing or Protein Power.

Are you a carbohydrate addict (CA)? You can take the test in the CAD/CALP forum. Many CAs can stall on Atkins due to eating more than 4 times a day or having foods on Atkins that spike insulin levels. Insulin is a fat storer, if your insulin if too high, you won't lose weight. CAD corrects that condition.

Hope some of this helped.
