"Stubborn" bellyfat

One of the latest products you see advertised on TV relates to Cortisol and belly fat. The commercial tells you that the hormone Cortisol, when released causes you to store fat around your belly.

The supposedly mechanism for this is as follows; when we get stressed our bodies release hormones to cause the sugar in our bloodstream to enter our cells rapidly so that we are able to move quickly as part of the “fight or flight” mechanism, that is we can fight with or run away from whatever is stressing us with a burst of energy. In today’s society we don’t generally respond to mental or physical stress by running away or fighting so we don’t use up this rush of blood sugar into our cells, therefore it is stored as body fat. Is this true? Absolutely not!

While it’s true that the hormone Cortisol is released during stress and is designed to cause the sugar in your blood stream to enter your cells quickly, this doesn’t increase your body fat.

Let’s go back to my blog about maintenance calorie levels. Say you’re an average male that weighs about 170 pounds. Your caloric maintenance level is approximately 2000 cal per day. This means that if you eat more than 2000 cal, you will add body fat, and if you eat less than 2000 cal you will lose body fat. Now let’s say that today you eat 2000 cal and that’s your total for the day. You haven’t gone over 2000 or under 2000 cal today. If you did not eat excess calories today, how could you possibly get fatter.

Even if you had a stressful moment and your hormones created these changes in your bloodstream you still couldn’t get fatter because you didn’t eat excess calories today.

This example represents a tactic that is typical in advertising. It sounds reasonable that if the sugar in your blood entered your cells and you did not use the energy in the fight or flight mechanism, then you would store this sugar as fat but it’s simply not true and not possible.
