A study published this week in Nature led by the University of Texas Southwestern Medical Center reports that, in mice, exercise induces autophagy in heart and skeletal muscle cells, which improves their ability to remain “young” and adjust to changes in energy and nutrition. The autophagy was associated with increased diet-related insulin resistance and lower rates of diabetes. These findings provide at least one mechanistic explanation for why exercise is associated with lowering diabetes risk.
A description of the study and interview with the researchers is available through Scientific American.

In a creative way, Dr. Mike Evans answers the question, “What is the single best thing we can do for our health?”. Dr. Evans, Associate Professor of Family Medicine and Public Health at the University of Toronto and physician at St. Michael’s Hospital, with an animation by Liisa Sorsa, says that exercise should be the first priority, with a goal of at least 30 minutes of activity per day. Dr. Evans draws on numerous findings both nationally and internationally that have highlighted the importance of physical activity for positive health changes. His primary message is simple: limit the number of hours you spend sitting and sleeping to 23 and 1/2, and use that final 30 minutes to benefit yourself.
