Type 2 diabetes, a disease strongly influenced by diet and lifestyle, affects 13 million Americans and threatens 16 million more whose blood sugar levels are above normal. In 2003, Reader's Digest published a book on its "ChangeOne" weight-loss program. Now, the publisher has adapted the regimen to fit the needs of diabetics, 90% of whom are overweight. Nutritionist Harper and journalist Laliberte walk readers through a step-by-step plan for making small changes that can lead to impressive results. They claim that following the plan will lower blood sugar by 25%, boost the body's cells' ability to respond to insulin and result in a loss of 10% of body weight. The plan is simple and doesn't count calories or limit carbs. Instead, it requires diabetics to keep food in their system, eat more frequently and consume balanced meals and smaller portions. Exercise is also crucial, as it reverses insulin resistance, decreases blood sugar and reduces the risk of high blood pressure, heart attack, stroke and arthritis, all problems common among diabetics. Sections on yoga-based exercises, easy-to-follow recipes and attractive photos lend a glossy magazine feel. With its strong focus on lifestyle and diet, this text will particularly interest those hoping to reduce or eliminate the need for medication. (Jan.) Copyright 2004 Reed Business Information.
