One of the wisest researchers who I know writes that exercise won’t help us to lose weight. But in my experience it does, and weight loss is crucial for almost all of us who have diabetes, because our weight is a big factor in high blood sugar levels.
“Appetite and thus calories consumed will increase to compensate for physical activity,” writes Gary Taubes in Good Calories, Bad Calories. When I read the first edition of this book in 2007, it finally convinced me that I could control my diabetes and my weight on a very low-carb diet. It worked: my current A1C is 5.4 and my current BMI is 19.2. Both of these numbers are big improvements over what they were six years ago.
In his subsequent book, Taubes elaborated on his statement. This doessound persuasive.
