I think one of the most frustrating things for me in my practice is when I get a patient who is not active physically. Often these patients are also overweight and/or have other problems that could be helped by exercise. They know they should be active, but for a lot of reasons they just can't get in the habit of exercising. In the book, "Move a Little, Lose a Lot", James Levine, MD and Selene Yeager offer some great scientifically studied non exercise solutions. They contend that we are suffering from a "sitting disease". What the authors recommend is doing non-exercise activity thermogenesis (NEAT), standing, bending, turning, walking, etc. during the day. Dr. Levine is Professor of Medicine in the Department of Endocrinology at the Mayo Clinic in Rochester, MN. I've linked to a People's Pharmacy Podcast and a very engaging YouTube, from the Mayo Clinic. If you only have time for one, watch the YouTube video, it is only 13 minutes. He's pretty inspiring.
