Many researchers have reported over the years that there is a relationship between activity levels and weight loss. In general, our findings support their reports, yet we have also observed that a rigorous exercise regime is not essential to the success of the diet, and other scientists have supported our findings.
Do these findings seem odd? They aren’t, really.
The explanation lies in the distinction between exercise and physical activity. Today, the word exercise is usually used to mean a programmatic pattern of activity, a planned regimen of regular running or swimming or other vigorous workouts. On the other hand, physical activity is less well defined: a job that requires considerable walking, for example, involves what we would term physical activity.
Thus, while exercise may make you feel good, look good, and stay healthy, it is not an integral part of the weight-loss component of this diet. At the same time, we do emphasize that you need to maintain a moderate level of physical activity (not necessarily a rigorous exercise plan) to help make the diet work for you.
So run or swim if you wish: there are many health benefits, and it may make1 you look good and feel better. But don’t do it solely to advance your weight-loss goals. Recall that it is a return to normal insulin balance that eventually produces weight loss in the carbohydrate addict.
In short, you don’t have to be in training for the marathon to lose weight: but you also can’t expect reasonable weight loss when you never get out of your easy chair.
As always, follow your physician’s recommendations, too.
