Zaggora HotPants Promise to Help Wearers Burn More Calories It's literally the hottest new trend winning over the fitness fashion-forward. The Zaggora HotPant is part of a clothing line that claims to help you burn more calories by making you not only look, but also feel hot. ABC News" Juju Chang visited Zaggora's founder, Dessi Bell, a 28-year-old investment banker turned workout guru, to give the pants a try. You can actually burn more calories by just wearing these clothes? Chang asked. "Because it makes you hotter," Bell replied. The body burns more calories when you get hotter. According to Bell, these pants will make you sweat while helping you melt off those extra pounds. "We found that wearing HotPants versus a normal garment helps you burn 11 percent more calories while you're exercising, but even an hour after you work out it helps you burn 13 percent more calories," Bell said. So it helps you burn calories even after you stop working out? "Yes," said Bell. Because you are hotter, so your body continues being hotter even after you work out. In 2012 alone, there have been fitness fads with everything from leg toning shoes to vibrating barbells, but despite all the other options, Zagorra has its true believers. The workout wear is selling like hotcakes, in part thanks to real women posting real reviews on the Facebook page, which now has more than 300,000 fans. "Our biggest market is moms, and moms are great because once moms get behind a product, they tell all their friends," Bell said. Bell originally came up with the idea for the HotPant after struggling to find an effective weight-loss and tone-up solution in time for her wedding. The HotPant, which the manufacturer says has undergone testing at the Chelsea School at Brighton University to prove its effectiveness, is designed with Celu-Lite technology fabric lining. To see the pants" benefits, however, its promoters say you must exercise with moderate intensity for at least 30 minutes. Chang visited the running team from LaGuardia High School in New York City to get some real reviews from the student athletes. "It feels more thermal," one team member said. It does feel like I'm sweating more, but in a good way.
