I don't know what your diet is like now, however, exchange anything white (bread, rice, pasta) for whole wheat or whole grain. Exchange
unhealthy sugary snacks for fruit, yogurt, etc. I hate to
excercise, and have absolutely no desire to join a gym. Instead, I walk every day. DH and I often do it together, and its sort of a nice "date" after a hectic day. I also make use of our community centre and swim at the drop in programs.
