Stress, Cortisol, and your waistline

Excess visceral fat is connected to several health issues

Do you struggle with extra fat around your midsection?  Excess abdominal fat is not only visually unappealing to some, but it also increases your heart disease risk.

What causes abdominal obesity?

There are many different reasons your body likes to store fat in the abdomen.  I want to discuss one possibility: Cortisol.

What is cortisol?

Cortisol is a hormone made by the adrenal glands in the kidney.  Cortisol levels are highest in the morning.  Through gluconeogeneis (term for glucose production), cortisol breaks down muscle to provide the body with needed glucose for energy needs.  Cortisol also relocates fat cell deposits into the visceral cavities of the abdomen.

Stress and Cortisol

When you are confronted with stress, your body’s initial response is “fight or flight.”  When we go into “fight” mode your body releases the hormone norepinephrine.  When you respond with “flight” (or anxiety), your body releases epinephrine.  If the stressful situation is long term and you begin to feel distressed and defeated, the hypothalamus in the brain becomes involved, eventually leading to the release of cortisol from the adrenal gland in the kidney.

Why is “fight or flight” important to understand?

Your perception of an event can determine your body’s physical response.  Do you feel stressed, but challenged by an obstacle or do you feel overwhelmed and out of control?  If you feel challenged and “fight” your body responds with an accelerated heart rate that increases the release of fatty acids into circulation.  If you feel out of control and defeated (“flight”), the body increases fat formation (lipogenesis), breakdowns tissue (muscle), suppresses the immune system, and increases visceral fat deposits.

What is visceral fat?

Visceral fat is the fat around and between your organs.  Subcutaneous fat is the fat layer beneath your skin.

Excess visceral fat leads to the “beer belly” effect (also referred to as the “apple” shape).  Visceral fat is connected to insulin resistance and glucose intolerance (linked to diabetes), high cholesterol, high blood pressure, and heart disease.

Are you at risk?

Get out a tape measure. 

Wrap the tape measure around your abdomen at the level of your navel (belly button).  Make sure the tape measure is level all the way around (you may need extra hands).  Resist the temptation to cinch in the tape measure for a lower number, instead hold the tape measure lightly against your skin. 

Men: A waist measurement of 40 inches (102 cm) or greater equals abdominal obesity.

Women: A waist measurement of 35 inches (88 cm) or greater equals abdominal obesity.

How to reduce stress for minimal impact on abdominal fat and heart disease risk?

Stress is a normal part of living, but you can take steps to reduce your stress levels.
