About Hot Shaper Hot Shaper is a new waist training belt that’s claimed to help you hide your belly, support your back and posture, burn more calories, and instantly look up to 2 sizes slimmer, while giving you a perfect hourglass shape. In order to accomplish this, Hot Shaper’s Neotex Smart Fabric features an inner layer that’s claimed to increase heat with skin contact, while the absorbent outer layer is claimed to “sweat away the calories” and keep you dry. In fact, Hot Shaper is claimed to help 87% of users burn more calories when doing the same workouts. On top of this, Hot Shaper is claimed to be so comfortable that you can wear it over or under your clothes. So what’s the deal with Hot Shaper? Can it really help you burn more calories while giving you a perfect hourglass figure? Consider the following: Will Hot Shaper Help You Burn More Calories? In short, no. Despite this, many other waist trainers also claim to help you burn calories, including Tummy Truck Belt , Xtreme Power Belt , and more. To explain, while the compression provided by Hot Shaper (more about this next) might help conceal some of your belly bulges, the reality is that “people who use devices such as waist trimmers and rubber sauna suits to help them sweat excessively during workouts are losing water weight, but not burning more calories to lose fat. As you sweat, your body loses a slight amount of weight due to the water it loses, but this type of weight loss is neither long-term nor effective. As soon as you consume water or another beverage after your workout, any weight you've happened to lose through sweat is quickly restored.” With this said, there was a disclaimer posted at the bottom of Hot Shaper’s website that read, “Hot Shaper users followed the Hot Shaper reduced-calorie eating plan and did a cardio workout regularly. *RSI - International Research Services , October 2013.” Unfortunately, it doesn’t appear that this study is available online, or directly through International Research Services’s website. Potential Hot Shaper Side Effects Despite the fact that Hot Shaper probably won’t do much more than temporarily flatten your belly, these types of compression belts and waist trainers can cause some real harm. This is because too-tight waist trainers can lead to: Compressed lungs, which can lead to breathing problems (especially if you’re working out intensely), and even rib damage. This reduced oxygen intake can even slow down your Metabolism, making it more difficult to burn calories. Acid reflux, since your stomach can be pushed up beyond your diaphragm. Abdominal pain due to bowel constriction, which can also lead to constipation. What is Neotex Smart Fabric? Outside of websites directly related to Hot Shaper, there wasn’t any additional information online about Neotex Smart Fabric. Because of this, it’s our opinion that’s it’s essentially just a neoprene sleeve, which the manufacturer has named for marketing purposes. Whatever you call it though, while this neoprene might make you sweat, it won’t necessarily help you lose weight or shed inches. Speaking of which, we find it hard to believe that Hot Shaper could comfortably be worn on the outside of your clothes, since you’ll almost certainly sweat through them quickly.
