I'm back home

I haven't exercized the last three days as I have been away. I'm going right after I write this. While I was away at my sister's, I didn't stay on my diet, but I didn't overeat either. The change in what I ate there helped me get off my latest plateau. I think when I'm always eating the same thing and exercising the same, my body adjusts and my weight gets stuck. I think this is what they talk about on the biggest loser-about having a high calorie day so your body doesn't think you are starving. I need to go as I am procrastinating about going to the gym.
