A February, 2009 article published by the New England Journal of Medicine concluded, in general, that when it comes to weight loss, the kind of diet that is used – low or high protein, fat, or carbohydrate, does not matter near as much as the amount of calories consumed or not consumed.
I agree. However, the amount of calories consumed is only half of the equation. The full equation is more to the order of the amount of calories consumed versus the amount of calories expended determines one’s body weight.
The big challenge to diets is that the body’s metabolism tends to slow down when caloric intake is significantly reduced. This is where ongoing physical activity becomes crucial. Ongoing physical activity increases the amount of calories expended and helps keep the metabolism from slowing as much.
Here’s the surprise for most people. We use two types of calories, carbohydrates and fat. Carbohydrates have to be metabolized before use. Fat does not. It is used directly. Here’s the good part. The higher the intensity of physical activity, the more we use carbohydrates. The lower the intensity, the more we use fat as a fuel source.
With this in mind, my advice is to take it easy. Not only will you tend to use more fat as your energy source, you’ll be less prone to injury. Most important, if you want to make your physical activity endeavor last thereby increasing the chances of a healthy diet, make having fun the priority!
