To maintain whole-body glucose homeostasis, coordination of three different metabolic events is required: adequate secretion of insulin by pancreatic b-cells, suppression of hepatic glucose production, and stimulation of glucose uptake by insulin-sensitive tissues, primarily muscle. Three potential rate-controlling steps and molecules for insulin-stimulated muscle glucose metabolism (i.e., synthesis of glycogen from glucose) have been identified: glucose transporter 4 (GLUT4), hexokinase, ...
Knowing your stage of change can help you discover what you need to do to move forward. The questions in Assessing My Stage of Change will help you gauge where you are on the spectrum between precontemplation and maintenance. section on pages 155-156 contains advice for people in the precontemplation stage, including many reasons to become active.
In addition to increasing the amount of time you are active, you can also increase your daily physical activity by cranking up the intensity. Light-intensity activity is any physical activity more strenuous than sleeping and less strenuous than a brisk walk. In the following space, write down two light-intensity activities that you are willing to crank up into moderate-intensity activities simply by picking up the pace.
For the participants in our study, obstacles to being active came in all shapes and sizes. One way to motivate yourself is to remember the important benefits that physical activity can provide. Benefits that our participants often listed included feeling productive, enjoying improved communication with a spouse, and feeling good about their bodies.
