But a former NASA scientist is behind the latest no-effort calorie burn. The description clearly states, "Let's be blunt: there is no magic pill for weight loss, and The Cold Shoulder is no exception to that rule. The cold, hard truth is that the foundation of weight control is your diet." The vest can burn up to 500 calories per day if used as directed, but you can easily nullify the effect by eating an extra 500 extra calories. But if you are already eating well and getting moderate exercise and want to accelerate your calorie-burning efforts by burning excess calories while at rest, there's no simpler, easier, or more time-efficient way than wearing our vest. Even if wearers wanted to exercise, they shouldn't, he said — for the vest to work, the body needs to be at a comfortable temperature. If you are in a hot environment, the The Cold Shoulder will help you stay cool, but it won't burn excess calories, because you're not cold. Remember that the goal of The Cold Shoulder is to force you to burn calories at a time when you otherwise would not: sitting down, at rest, in a comfortable environment at room temperature. So, to burn excess calories, wear The Cold Shoulder sitting on the couch watching the game, or in front of your computer, or in your car during your commute. Hayes, an associate professor at the University of California-Irvine, hopes it's a way for people to burn calories and even combat obesity. The latest volley in the war against weight is a Kickstarter project called the Cold Shoulder. Basically, if you extract heat from your body, even if you’re sitting on your couch in front of the T.V., your body will need to burn calories to stay warm. There have been some scientific studies in this direction, including a look at whether cold acclimation could be used to combat obesity.  The Cold Shoulder 
 
 From the ThighMaster to allegedly fat-burning Japanese underwear, people will try almost anything in the quest to tone up and lose extra pounds. The vest looks like this:

 I have put it to the scientific test and proved this vest's efficacy in controlled clinical trials. After giving birth to their 10-week-old, she started wearing it to burn pregnancy weight while unable to exercise. A discomfort that only lasts the first few times, he promises. The Cold Shoulder 
 
 The Cold Shoulder vest is designed to go into a freezer. "None of those things are comfortable or practical," he said. Then, you take it out and wear it over a shirt (to protect your skin). Hayes said he's worn it to fancy French restaurants and even as part of a three-piece suit. The idea is to make your body work harder and burn calories. "The first couple of seconds, you'll feel like, 'Holy cow, this water is freezing.' Our vest, The Cold Shoulder, has ice draped over the shoulder and across the back: 
 
 Due to the temperature difference between the body and the ice vest, heat flows from the body to the vest, causing your body to burn calories. Put together after Hayes mulled the body's natural tendency to burn calories when cold, the initial vest could burn as many as 500 calories a day, or a pound of fat each week. In order to cover the costs of fabric and production at this level, we need to commit to this minimum order quantity to secure the best deal, which can then be passed onto you, with special rewards exclusively offered here on Kickstarter! Once the vests are made, we’ll prepare them for shipment (at most 1-2 weeks), and then ship them to your door (2-3 days Domestic US, or 1-2 weeks International). I wore it for a few minutes before bed every night and slept much more soundly than I had done for months.”– Mike Sirak 
 
 “Thanks to The Cold Shoulder I was able to eat 6000 more calories over two weeks while having friends and family visit without any weight gain. Please follow us on Twitter and help by tweeting about the campaign!
– If you've ever wished you could burn a fair amount of calories just by sitting around, and you don't mind that just-jumped-into-a-swimming-pool feeling, a NASA scientist may have a solution: his Cold Shoulder Calorie Burning Vest. Dr. Wayne Hayes, who has studied both ice and the effects mild cold exposure have on calorie burn, designed the vest to take advantage of the body's tendency to try to warm itself in cold conditions. He tells the Chicago Tribune that wearing a freezing-cold vest may not be the only way to expose oneself to mild cold conditions, but it sure beats the pants off, say, running nearly nude in February, which he calls neither comfortable nor practical. But apparently a $199.99 vest with ice packs that feels "just like jumping into a pool" is a no-brainer, and earlier this year 1,524 backers raised an astronomical $281,319 for Hayes' idea on Kickstarter. (He originally asked for $13,500, reports CNET.) Hayes recommends wearing it for 60 to 90 minutes twice a day. A handful of testimonials from early Cold Shoulder testers suggest enticing results, but a larger sample size is about to put the vest to the test now that the first Kickstarter orders shipped out in September. Being a scientist, Hayes wants to make one thing perfectly clear: "Let's be blunt: There is no magic pill for weight loss, and The Cold Shoulder is no exception to that rule. The cold, hard truth is that the foundation of weight control is your diet." The vest, he proposes, is simply a way to accelerate calorie burn for those already eating well and exercising.
