I enjoyed another article I read at diettogo.com. It was entitled "What You Need to Know About Your Metabolism" by Alicia Kirchenheiter. As I get older, I realize I cannot eat as much as I used to. I find that eating smaller amounts of food more often keeps me satisfied and keeps me from gaining weight. As long as I am doing my gardening and riding my bicycle to work each day, I don't have to do aerobic exercises. I enjoy doing yoga and lifting weights and can watch movies or do other things at the same time. I also get up and walk around often while I am at work. I have my printer in another room from my computer. The suggestion to drink plenty of water is also a good one, especially in hot weather.
