Most people admit that when theyre under stress, healthy eating habits can be difficult to maintain. Whether eating to fill an emotional need or grabbing fast food simply because theres no time to prepare something healthy, a stressed-out lifestyle is rarely a healthy one. But weight gain when under stress may also be at least partly due to the bodys system of hormonal checks and balances, which can actually promote weight gain when youre stressed out, according to some researchers. Cortisol is a critical hormone with many actions in the body. Normally, cortisol is secreted by the adrenal glands in a pattern called a diurnal variation, meaning that levels of cortisol in the bloodstream vary depending upon the time of day (normally, cortisol levels are highest in the early morning and lowest around midnight). Cortisol is important for the maintenance of blood pressure as well as the provision of energy for the body. Cortisol stimulates fat and carbohydrate metabolism for fast energy, and stimulates insulin release and maintenance of blood sugar levels. The end result of these actions can be an increase in appetite. Cortisol has been termed the stress hormone because excess cortisol is secreted during times of physical or psychological stress, and the normal pattern of cortisol secretion (with levels highest in the early morning and lowest at night) can be altered. This disruption of cortisol secretion may not only promote weight gain, but it can also affect where you put on the weight. Some studies have shown that stress and elevated cortisol tend to cause fat deposition in the abdominal area rather than in the hips. This fat deposition has been referred to as toxic fat since abdominal fat deposition is strongly correlated with the development of cardiovascular disease including heart attacks and strokes.
