A study published in the Journal of Strength and Conditioning Research looked at the calorie-burning effects of a 50-minute Body Pump workout. Subjects burned, on average, 265 calories during the workout. The men burned a little more calories (315) compared to the women (214).
Since popcorn is 100% whole grain, itâs also a good source of fiber, and as long as you air-pop it and donât douse it in butter, oil or salt, it wonât add much artery-clogging fat to your diet. But the findings arenât license to substitute popcorn in your diet for fruits and vegetables, says Vinson.
If you do opt for pretzels, look for ones made with whole-wheat flour as the first ingredient. Fiber: Popcorn also naturally contains a fair amount of fiber: 3 to 4 grams in each 1-ounce serving. You wonât find too much fiber in pretzels, with less than 1 gram per ounce, although whole-wheat pretzels can have up to 4 grams per 1-ounce serving. Lower in Calories: With popcorn, you get to more food to snack on, without eating more calories, because popcorn is so airy. Even though both deliver about 100 calories per ounce, a serving (about 1 ounce) of popcorn is a satisfying 3 cups, compared with 1 ounce of pretzelsâjust a mere 2 handfuls.
