Stress and Weight Gain

Pizza and Pop Tarts never solved anyone’s problems, but that doesn’t keep us from seeking comfort inner favorite food. When life gets hectic, when plans fall through, when relationships blunder, we often try to calm our minds by seeking comfort in foods.

“Everybody has their own comfort food,” says Marci Gluck, PhD, a research clinical psychologist with the National Institutes of Health. A bag of chips, a big plate of macaroni and cheese, or a carton of mocha fudge ripple ice cream can all make a person feel better, at least temporarily.

The disadvantage of comfort foods

Food we choose for therapy has an obvious downside: While it may be temporarily comforting, it’s also long term fattening. Everybody knows that obesity rates have been climbing steadily over the decades and that we live in stressful times. Is it possible that we’re simply trying to eat our way out of misery and into happiness? Is stress making us fat?

Stress, appetite and weight gain connections

Recently, scientists have discovered surprising connections between stress, appetite and weight gain. Simply stated, the chemicals that we produce during stressful times can help determine what we eat and how we store fat in our bodies.

Despite what some late-night commercials claim, this new understanding has not led to any magic-bullet treatments for weight loss; you can’t slim down simply by taking a pill that supposedly blocks stress hormones.

But recent research does help drive home a point that many psychologists and weight-loss specialists have been making for years: Managing stress can be a crucial first step toward successfully losing weight.

The cortisol connection

When we feel stressed out, our bodies resort to chemical hormonal warfare. Unsettling deadlines, major traffic jams, or arguments turn on an alarm in the brain that triggers the release of stress hormones. As a key part of our defense, the adrenal gland starts releasing large amounts of the hormone cortisol, which is a chemical that helps prime the body’s “fight or flight” response.

Cortisol gets a lot of attention in both medical journals and the press, and for good reason. For one thing, it seems to play a major role in all sorts of stress-related health problems, including heart disease and weakened immune systems.

It also helps control the buildup of fat, a process of deep interest to just about everyone. In times of stress, cortisol can collect fat from the blood and other storage places in the body and move it to the belly. Cortisol can also increase the size of individual fat cells. For some people, waist size may be an outward sign of stress. A study published in Psychosomatic Medicine found that women with mostly abdominal obesity tended to produce especially large amounts of cortisol when faced with a difficult task.

Control Cortisol Hormones

Cortisol isn’t the only hormone released during stress, and it’s certainly far from the only hormone that controls appetite. For these reasons, Gluck says, it’s overly simplistic to say that cortisol alone causes weight gain. Likewise, she says, it’s unrealistic to think that so-called cortisol-blocking supplements could aid in weight loss — and that’s assuming such products can even reduce cortisol levels in the first place. “I’m sure they don’t work,” she says.

Still, there’s little doubt that cortisol affects food choices. Studies in both animals and humans suggest that the hormone may help stoke an appetite for high-energy foods loaded with fat, sugar, or both. As reported in a 2003 issue of the Proceedings of the National Academy of Sciences, rats that have their adrenal glands removed suddenly lose all interest in sugary drinks, but will still happily eat their rat chow. (Interestingly, they no longer want to run in their wheels, either.) When injected with the rat equivalent of cortisol, they suddenly develop a taste for things like sugar and lard — at the expense of their regular food.

Manage Stress for better Weight Loss

The same study found that sweets and fats can quiet the stress alarm in a rat’s brain. The flood of stress hormones slows down, and the rat suddenly acts less annoyed. If it could talk, the rat would probably say it feels calm — the same feeling that humans often find at the bottom of an ice cream carton.

Gluck points out that it’s often hard to translate findings from animals to humans. “There’s just so much more going on in people,” she says. Still, a few studies suggest that cortisol can encourage people to overeat, too. For example, a study published in Psychoneuroendocrinology found that women who produced large amounts of cortisol during stressful situations also consumed more calories afterward.

Stressful binges

Gluck and colleagues published another intriguing study that suggested a link between cortisol and eating habits in humans. As reported in the Annals of the New York Academy of Sciences, subjects who were prone to eating binges tended to have higher levels of cortisol both when they woke up in the morning and after they completed a physically stressful task.

Gluck believes that stress may be especially dangerous — and especially fattening — for anyone with binge-eating disorder, a condition that causes people to periodically go on eating sprees that are beyond their control. As Gluck and colleagues noted in the Annals of the New York Academy of Sciences, roughly 30 percent of people who seek medical treatment for weight loss have the disorder. The researchers point to stress as a key trigger of the disorder’s onset. However, binge eaters aren’t the only ones who overindulge when times get tough. “There are definitely people who are not binge eaters who overeat during stress and gain weight,” Gluck says. While binge eaters feel like they lose control over food, other people may make a conscious decision to go for that extra brownie or slice of pizza, perhaps with the idea that a stuffed stomach will take their minds off their troubles.

Managing stress, slimming down

Whatever a person’s basic approach to eating, lingering stress can scuttle any efforts to lose weight. In the words of a report from the American Psychological Association, “Weight loss is never successful if you remain burdened by stress and other negative feelings.”

If you’re facing twin battles against stress and weight, calming your mind should be your first priority, Gluck says. “Addressing stress would be more effective than going on a diet,” she says.

Laurel Mellin, a clinical psychologist  has designed a weight-loss program that addresses this issue. To drive down the urge to overeat, people must first find the tools to nurture themselves and to set limits. Among other things, she recommends simply asking yourself two basic questions. These questions are “How do I feel? What do I need?” Besides learning how to detect and deal with buried feelings and needs, exercise will help relieve stress and find balance.

Activity to reduce Cortisol Hormones

Of course, there’s no one-size-fits-all remedy for stress. Some people find relief through physical activity, relaxation exercises, yoga, or meditation. Others need to see a psychologist who can help them adjust their outlook on life and their approach to food. Still others may need to make lifestyle changes, perhaps including more long walks and fewer late nights at the office.

The American Psychological Association does offer a few other tips for people trying to lose weight:

• Think about what you eat and why you’re eating it. Do you tend to overeat when you feel upset or sad? If so, remember that there are healthier, more effective ways to cope with stress.
• Avoid radical changes in your diet or activity level. Trying to reinvent yourself overnight will only add stress to your life. Instead, make changes slowly. For example, you can cut down the portion sizes of foods. Try switching to entirely new foods.
• Get support from family and friends. Encourage your entire household to make healthier food choices and find an exercise buddy. As a bonus, you’ll find that social support is an excellent buffer against stress.

Ice cream and chips can make a person feel better, but the feeling won’t last. In the end, staying healthy is the ultimate victory over stress.
