I think attitude has something to do with losing too. I have been stalled for months now, gaining and losing the same 3 or 4 pounds. I have been careful to keep a food diary, so I know that I haven't been eating too many carbs. However, my attitude was terrible. "OH, poor me, I work so hard and don't lose, while my husband and daughter lose so easily!" last week I decided to lighten up and have a more positive attitude. I lost 4 pounds this week, with no other change (same number of carbs, exercise, and percentages of fat, carb and protein.) I don't know why it worked, but I'm happier, and so is my family.
