I am a 59 year old female who has not lost any weight on an extremely low carb (south beach) diet
after 4 weeks. Several years ago,
I was successful
losing weight using this diet, but
not now. I had a benign brain tumor removed successfully in 2006 (after the weigth loss), and the surgery caused some numbness in my legs which gives me problems exercising, but I walk daily. I have been gaining weight since the 2006 surgery, and am at a loss as to what to do now. What's wrong?
