I just got back from vacation. I lost 7 lbs that week. All I did different than my normal life is that I didnt eat fast food and I walked to and from the beach daily, plus walked up and down three flights of stairs several times a day. I have read that you must walk 30 or 45 mins a day to lose weight. So, my question is , can I not do short spurts of excercise several times a day and still lose weight and stay healthy? It seems it worked for me that week.. was that just a fluke? xoxoxo Stace
