Good luck! I think the two things above are really important things to do for your health (no matter what your weight is but they help you lose weight). Remember, it will take time for your body to get used to the changes so don't be too hard on yourself when you mess up; just try again. When we don't exercise, we lose muscle mass making our metabolism slow down. After you exercise for a while, it will get easier and you will feel better. That cute dog is inspiring!
