Pick and Pass: Best Summer BBQ Foods

Pass: Margaritas

"Mojitos are generally less in calories than a margarita," says Mosier. That's because mojitos use plain club soda (which is a big zero on the calorie scale), while margarita mix is about 100 calories for four ounces. "If you really want a skinny drink, order a mojito, skip the sugar and use a zero calorie sugar substitute instead," recommends Mosier. Also add lots of ice—it cuts the calories and sugar while also causing you to sip your drink a little slower.

Pass: Potato Salad

Potato salad tends to come with a lot of extra fat because of all the mayo used to make it. Beyond that, potatoes are usually higher in sugar than baked beans (as long as you drain the sweet sauce baked beans sometimes swim in). Mosier says to go with the less starchy choice, as potatoes can spike your blood sugar levels and leave you with an increased appetite later in the day.

Pass: Chips and Guacamole

"Though guacamole has a lot of heart healthy fat in it from the avocado, it's still pretty high in calories," says Mosier. "As long as you are judicious with the dip (like hummus) you choose, non-starchy veggies are the better choice."

Pass: Apple Pie

According to Mosier, apple pie is loaded with sugar, plus an average slice can clock in around 400 calories! Angel food cake is fat-free and has a lot less sugar. One slice will only set you back 100 calories, making this dessert the blue ribbon winner.

Also Pick: BBQ Chicken

When it comes to the main attraction at a summer BBQ, these two options are about dead even in calories while both being a great choice of lean protein. Mosier says to look at how each is prepared—if the chicken is grilled with its skin on and can be taken off, that's probably your best bet. Other than that, pick the one that appeals to your palate.

Pass: Coleslaw

"Although coleslaw is made with cabbage (a super low calorie veggie with a surprising amount of vitamin C), it's also prepared with a lot of oil, like mayo and sugar," warns Mosier. "to be safe choose corn on the cob and go easy on the butter and salt." Another bonus: Corn on the cob is a controlled portion, so you're less likely to overeat!
