Take the "health halo" effect, for example. By simply labeling foods with healthy-sounding names, manufacturers and restaurants can get you to eat more, regardless of how nutritious (or not) the snack may be. Earlier this year, a study in the Journal of Consumer Research found that people, particularly those with a history of dieting, tended to consume more when a food had a description such as "fruit chews" than when the identical nosh was called "candy chews." And snack-size packaging--which supposedly was introduced to help us manage our eating--may only make matters worse. A different study in the JCR found that dieters inhaled significantly more calories from mini packs of cookies than from standard-size ones. When you finish one bag and still aren't satisfied (the portions are really small, after all), you dig in to another--and then another, says lead study author Maura L. Scott, Ph.D.
They give us a rush
"Like doing the laundry or going to work, eating meals is often seen as routine and obligatory," says WH advisor Susan Albers, Psy.D., author of But I Deserve This Chocolate! "Snacks, in contrast, feel like a gold star for a job well done." Plus, because they tend to be sugary, fatty, or salty, they trigger the release of dopamine, a neurotransmitter that elicits feelings of euphoria, much like the feel-good rush of a triumphant shopping trip or a roll in the hay. Even the best salad, like it or not, won't inspire that kind of biological reaction.
How to Snack Smarter
The secret is simple: You have to rethink what a snack is--or isn't, says WH weight-loss columnist Keri Glassman, R.D., author of The Snack Factor Diet. It isn't dessert, for example. A snack doesn't have to be sweet, chocolate-dipped, or more than 150 calories. "It can be real food, like a packet of oatmeal with 10 walnut halves sprinkled on top," says Glassman. And the experience can still be indulgent if you focus on taking a break and recharging your body. More ways to make your treat go further:
Cut It In Half
A 2010 Journal of the American Dietetic Association study found that people who were given the same snack, either whole or cut into halves, consumed half as much when eating the latter, possibly because they considered only the number of items (not the size of the items) they ate.
Albers has a few tricks she uses to avoid mindless munching: No eating from a serving bowl, out of a big bag, or while standing at the kitchen counter. "Everything I eat goes onto a dish, which helps me keep portion control in mind," she says.
Besides helping you feel full, chewy foods may brighten your mood too. A 2009 study in Physiology & Behavior suggests that the act of chewing can decrease the level of stress hormones in the body. The mechanism may be physiological (chewing can increase blood flow) or psychological (either chomping diverts our attention from stress or we simply associate it with mealtimes, when we tend to be relaxed).
Make You Own Snack Packs
Dole out small portions of your favorite snacks into plastic ziplock bags. Scott believes that homemade servings don't trigger the same overeating as store-bought packs because the size of the food isn't deceptively smaller--only the amount you're allowing yourself to eat is limited, preferably to a portion that satisfies you.
Some eats can be downed with near abandon; others need to be reined in. Try these snack suggestions from Keri Glassman, R.D.
