Cut calories? If only it were that easy……

Finally, a great piece in the New York Times last week to only add to the confusion.
First, the linear thinking: if one pound of fat is 3500 calories, then wouldn’t it make sense to simple cut our intake by a small amount, say 100 calories, daily? That way, in a little over month, we would be down one pound, right?
Wrong. It’s an argument that I am sure many of you are tired of hearing from me. Nothing about the health and well-being of the complex systme known as your body is ever that linear. The Journal of the American Medical Association (JAMA) notes that this line of thinking fails to take into account the body’s adaptive qualities. As you take in slighty fewer calories, you will lose a few pounds but then your body will adapt to function with a lower intake. As you take in a few more, it will adapt to function with the higher intake. The extra calories go to supporting the new extra weight.
But I still want you to think about the small steps.
Combine this with an increase in physical activity and the benefits increase. Now, start working out at a very high level, the “zero to 60″ theory of January 1st, and your body is going to crave the extra calories to support the new stress and strain of all the work. Fail to give the body the right materials and you are setting yourself up for breakdown. However, cut back slightly on the calorie intake, you can then increase your activity level slightly and start to roll back the dial on the scale. Then increase the activity level, then decrease the calorie intake…… you starting to get the picture?
The key is working intelligently and strategic and listening to your body. Cutting out 100 calories a day? You should be able to do that without blinking and without that horrible feeling of deprivation. Increasing the number of steps you take daily by 2000? Again, very easy to incorporate into your agenda if you know what to do.
But strict focus on calories in/calories out? Eventually your body is going to catch on and balance itself out……and then you are going to be frustrated……
…….and, of course, that’s not even taking into account what those calories are comprised of……..
