Should we put our mind to it, go for it, get down and break a sweat?

treadmillA recent story in Time Magazine made a bold statement by proclaiming that while exercise and physical activity may improve physical and mental health, it may not help you lose weight. As the author acknowledges, there are a number of reasons this might occur. Physiologically, exercise can prompt the release of hormones that stimulate hunger, causing people to eat more. Additionally, as the article discusses, some dieters often reward themselves after workouts by consuming high-calorie foods that merely replace the calories burned during the workout.

Another possible explanation addressed in the article looks to social psychological research performed by Roy Baumeister and colleagues. In their pivotal studies about self-regulation, they found that when people are depleted of the energy to exercise self-control, they often engage in disinhibited behaviors, such as eating more. These studies have interesting implications for weight loss and exercise. For instance, people who are exercising frequently might also be dieting to lose weight. Dieters often employ substantial self-restraint throughout the day to resist tempting food. Thus, it might not be exercise that is leading to increased eating; rather, the frequent self-monitoring process of dieters may deplete them of the energy needed to resist fattening foods. On the other hand, exercise lowers blood sugar levels, including that of glucose, which has been intimately linked to self-regulatory abilities (Gailliot et al., 2007). Is it the case then that post-exercise hunger, which often leads to the consumption of high-sugar food, is simply the body’s way of returning to homeostasis?

It seems that social psychological research will have much more to say about this topic in the future, as it remains unclear whether it is dieting or exercise that is directly leading to the consumption of fattening foods. And if the booming weight-loss market tells us anything, it’s that people want to know the best way to get fit and look good.

Help our overweight children

childhood-obesity-by-joe-huObesity has been rated as the No.1 health problem for American children, according to a 2009 poll conducted by C.S. Mott Children’s Hospital. Up to one out of every five children in the U.S. is overweight or obese, and this number is continuing to grow. Obesity places children at risk of developing chronic diseases such as heart disease and diabetes later in life. The overweight children are also more prone to be depressed, anxious, and withdrawn, and report low self-esteem.

Children become overweight and obese for a variety of reasons. The most common causes are genetic factors, lack of physical activity, unhealthy eating patterns, or a combination of these factors. For example, psychologists explain that a combination of environmental pressures (e.g., parental concerns about children’s safety), technological factors (e.g., labor-saving devices such as cars), and societal transitions from childhood to adulthood are likely to increase sedentary behaviors, which usually coexist with eating, resulting in weight gain in children (Hills et al., 2007).

Although factors associated with and possible causes of obesity are complex, a child’s total diet and activity level play an important role in determining a child’s weight. Today, many children spend a lot time being inactive. For example, the average child spends approximately 4 hours each day watching television. As computers and video games become increasingly popular, the number of hours of inactivity may increase. Reducing the prevalence of childhood obesity is a public health challenge, and schools and parents have the potential to play a powerful role in diminishing this serious health crisis.

Divorce hurts health even after remarriage

man woman hands holding broken heartLove is a miracle and happy romantic relationships might be the best gift for most people in the world. In fairy story, marriage is always the ultimate happy ending of romantic relationship. In reality, about 2.4 million American couples marry each year; during the same time period, half or more of these marriages fail as the result of the departure or death of a partner, most often during the second to sixth years of marriage (US census bureau, 2005). What happens when the sweet dream of marriage falls into pieces?

A new study shows that divorce or losing a spouse to death can exact an immediate and long-lasting toll on mental and physical gains, even after remarriage. Romantic relationships don’t end easily because they involve the investment of one’s time and feelings, the exchange of powerful rewards, and commitment. However, once the romantic relationships end up, people will experience not only the loss of caring, affective support, intimacy, and companionate love, but also extremely stressful and miserable feeling of pain, loneliness, helplessness and hopelessness. Besides, people ignore their health; they’re less likely to go to the doctor; they’re less likely to exercise; they’re sleeping poorly. Remarriage helps people get back on a healthy trajectory, but it puts people back on a healthy trajectory from a lower point, because they didn’t take care of themselves for a long time! Divorce operates like a traumatic event in one’s life; it damages not only your romantic relationship, but also your health.
