Game on—and it's your willpower up to bat! We asked nutritionists across the country how to hit concession stands without putting thousands of empty calories on the scoreboard.

Do: Choose grilled chicken

These sandwiches are a stadium slam dunk. A ballpark burger can pack up to 500 calories and as many as 10 grams of artery-clogging saturated fat (and that's before cheese and toppings), but the sandwich often comes in at around 300 calories with half the fat.

Do: Get cracking on peanuts

Craving popcorn or Cracker Jacks? Opt for plain, unsalted, in-shell peanuts instead, said Chicago dietitian Amari Cheffer, registered dietician (R.D.) and licensed dietician-nutritionist (L.D.N.). They've got heart-healthy monounsaturated fats, Vitamin E and magnesium—and the act of cracking the shell makes you work a little harder to enjoy them. The catch: A typical eight-ounce bag is much larger than one serving (it can have over 800 calories total), so don't eat more than a quarter of it yourself.

Don't: Sip sugary sodas

Save a cool 100 to 300 calories by sticking to sparkling water, unsweetened iced tea or ice water with lemon. But if a ballgame just isn't the same without soda, don't stress, said New York City-based Marissa Lippert, R.D. Just order a small size and fill it to the brim with ice.

"You're addressing your craving strategically," she said, "since your body won't know you're taking in 10 or 20 percent less soda."

Don't: Get a "personal" pizza

Seek out a single slice of plain cheese or veggie instead of devouring a whole personal-pan pie-size portion (which packs about 200 additional calories). The (pizza) can actually deliver heart-healthy benefits, since tomato sauce contains lycopene, an antioxidant.

"Interestingly, it's been found to be especially well-absorbed in pizza," Seattle-based Minh-Hai Tran, R.D. and certified specialist in sports dietetics, said.

Do: Be choosy about beers

Love your ballpark brews? There's no need to deny yourself, just stop at one or two 12-ounce pours. Choose a low-calorie option like Amstel Light (which has just 95 calories), said New York City-based Keri Glassman, R.D., and author of "The New You and Improved Diet." Or sip a stout beer: Guinness is another low-cal brew (you'll get 25–30 calories less than a regular beer) that also happens to be high in antioxidants.

Do: Lighten up on the toppings

One fan's harmless hot dog can be another one's diet strikeout, and the difference is in the topping. A chili cheese dog can contain upwards of 700 calories, while a plain frankfurter should be closer to 300.

"Keep condiments relatively clean," Lippert said, "with just mustard and maybe some relish or sauerkraut so at least you're getting some vegetables."

Do: Create your own portion sizes

Most ballparks offer veggie and turkey versions of burgers and hot dogs, which are almost always a better pick than low-quality stadium beef, Lippert said. But a healthy serving should be about four to six ounces, she said, which means you should aim to eat only half to three-quarters of the concession-stand-sized portions. Bonus? Skip the bun to shave off another 100 calories.

Do: Seek out salads

Once impossible to find at ballgames, pre-made salads are popping up on concession stand lineups.

"Fresh produce is a great source of nutrients at a low calorie cost and a healthy way to stay full at the game," Glassman said. A typical stadium salad has a not-so-bad 200 calories a serving—as long as you avoid creamy dressings and stick with olive oil or a balsamic vinaigrette.

Do: Pick a parfait

Most ballparks are upping their gourmet options, but trendy foods don't necessarily translate to healthy choices. At Dodgers Stadium, Avanti satisfies her sweet tooth with a strawberry yogurt parfait—a much better option at about 200 calories than, say, a chocolate cupcake's 400 or so calories.

"Think to yourself, the amount of exercise I'd need to burn off that cupcake is one hour of climbing steep stairs," she said.

Do: Brave the sushi

It may not be as American as apple pie, but ballpark sushi is increasingly easier to find, Glassman said. At Yankee Stadium, spicy tuna rolls rack up about 195 calories, and veggie rolls about 160.

Don't: Eat mindlessly

While noshing, tear your eyes off the game and try to savor each bite. Otherwise, you may find yourself holding an empty container and still feeling unsatisfied.

"A number of studies show that eating while distracted results in eating larger quantities of food," Tran said. "And at least one study showed that people who ate while distracted even had a hard time recalling what they'd eaten."
