Here's your reality check, Angi -- you're doing great!
You're losing inches, your clothes are looser, you're getting fitter and stronger ... wow, it all sounds perfect!
Screw the scales! Your weight is only a number and isn't a very good indication of progress. Remember, that number isn't tattooed on your forehead for the world to see ... what they see is YOU and it sounds like there's a lot less of you these days!
Who knows? The scale at the doctor's office may be off - is it the same one you weighed on last time? If not, then you're comparing apples and oranges, but even if it's the same scale, sometimes scales that are used a lot need to be recalibrated.
I think your calories are right in line where they should be. Are you focusing on healthy choices? As for exercise, have your increased the intensity of your walking? Do you have access to any other cardio to mix things up (gym equipment, bike, swimming)? Would you consider mixing in some easy jogging?
Good for you for starting with weights! Squats and lunges are outstanding lower body exercises! Are you working out in a gym or at home? Have you ever tried DVDs? Have you checked out any of the stickies in the Ladies Who Lift forum for some more ideas for workouts?
Boy, I hope you find that whooshie fairy too
but until then, I think you're doing everything right and building habits that will get you to goal ... and keep you there.
Keep up the good work!
