Thanks for the input, Steelslady. I am a bit leary of calories that low, but according to Dr. Katahn (who at the time of the book was a weight loss researcher at Vanderbuilt University), the alternating calories and consistent exercise part of the program prevent the metabolism from slowing down and shouldn't pose any health risks for people who have not existing health problems.
That being said, if I try it and the calories are too low for me, I will definitely up them. In past programs, I have gone as low as 600 calories before, and it was tough. I just don't think I have the energy to stick with a longterm weight loss plan any more, and I'm just heartily sick of this 20 lbs. that's preventing me from fitting into most of my clothes. I guess I have an attitude problem right now!
Thanks, again, for the input.
