Boy I have been there! I finally stopped dieting when I took on a management job with a lot of responsibility and found that I couldn't afford to be too hungry to think clearly. Cucumbers when you're hungry? That wouldn't keep my brain functioning. During my dieting years I remember getting too hungry to do my job (I think chronic dieting was one reason I got stuck in dull jobs where you can go on autopilot), being so befuddled by low blood sugar in the hour before lunch on various occasions that I lost my ATM card, broke three typewriter ribbons in a row (this was in the 1980s), lost a package I was supposed to take to FedEx, and the list goes on. I am not obese and actually am only medically overweight now because I am four inches shorter than I was 10 years ago. I eat six times a day, always something with protein and fat, almost always feel alert and centered, and so, I have a BMI of 26. So what? The wonderful thing is that a weight/BMI that was elephantine for a 12 year old is less than the national average for someone almost 69.
