Hi Carrie:
I am right there with you. I eat super healthy and excercise about 5 times a week and am still 5 lbs away from where I want to be. And let's not discuss my flabby belly : )
I think what works is trying new things, especially things that you can have fun with.. tennis, volleyball, swimming long distance, trail running, basketball, road biking, yoga, pilates, tai chi, etc. Not only will something fun encourage you to do it more often, but your muscles will respond better if they are exposed to new challenges. I just started playing tennis again and I was pooped after 1 1/2 hours of singles. It so fun and a great workout.
Also, now that it's summer, you might make a vow to bike to as many places as possible, as opposed to using your car. Not only will you help the environment, but you'll burn tons of calories while you're seeing new things. My husband and I are going to try that this summer and I'm really looking forward to it. I'll bet I'll eat less at a restaurant knowing I need to get on a bike afterward.
And lastly, I've heard from many people in your situation that a detox diet helps them get to where they want to be, especially if nothing else has worked.
Good luck,
Joelle
