These days, it seems that everyone is stressed. We all have too much to do and too little time to do it. Times are tough, money is tight, and deadlines are imminent. |
What happens when you're stressed? You tend to eat more, sleep less, skip the gym and feel rundown. Additionally, stress is linked to a number of illnesses, such as heart disease, high blood pressure and an increased risk for cancer.
No wonder so many of us are gaining weight. A study in the July 2009 issue of the American Journal of Epidemiology studied stress related work demands, difficulty paying bills, strained family relationships, and depression or anxiety disorders in a nationally representative group of 1,355 men and women for more than nine years. The overall result? Men tend to gain weight when unable to make decisions at work, learn new skills job or perform interesting job duties. More types of stress affected women's waistlines, according to the study. In addition to weight gain associated with financial problems or a difficult job, women also gained weight when dealing with strained family relationships and feeling limited by life's circumstances. Overall, this study found that people who reported increased stress gained more weight if they already had higher body mass indexes. In other words, if you're overweight already, you're even more likely to gain weight when under stress.
Although everyone handles stress differently, these researchers believe that when coping with life's stressful periods, people change their eating behaviors—and not for the better. Food isn't the only factor that influences stress-induced weight gain; a person's gender, the types of foods they eat, and whether or not the person is already overweight or obese are all contributing factors. This explains why some people gain more weight under stressful circumstances, while others may gain just a little or even lose weight.
It's obvious that to fight weight gain or to lose weight permanently, we have to control and manage the stress in our lives. How do you do that? Why does the body react this way to stress?
The Science behind Stress
Stress serves an evolutionary purpose. Think back to the early caveman days when bills weren't an issue but saber-toothed tigers were. In preparation for a possible attack, our body's neuroendocrine system would send out a "fight or flight" set of hormones: adrenalin, corticotrophin-releasing hormone (CRH) and cortisol. Adrenaline gives us instant energy, CRH decreases appetite initially, but later, after the threat is long gone, cortisol can increase appetite to make up for energy that was lost fighting the tiger or running away.
