Gwen- I love your attitude. Major round of applause!!!
I do have one concern-- the amount of calories you're eating. Not less than 1000, but no more than 1400 PLUS exercising 5 days a week. Depending on how much/how hard you exercise, you may find your calorie intake too low at 1000 and just right at 1400. I do at least 14 hours of cardio a week (that includes all my martial arts classes and going to the gym for an hour, plus soccer on Fridays) and 1400 is at the extreme LOW end for me to function.
Tip: If you find yourself stuck on one weight after a couple of weeks, up the calories by 100 per day until you start losing again.
Why? Your body needs fuel (food); if it doesn't get any, it'll keep the calories you've been eating "in storage" to use when you're exercising.
But seriously, I applaud you and I'm stealing your post as an inspiration for me to do better. Thank you.
