I’ve heard it before, you use a body wrap and you lose significant amounts of weight.  You melt away the fat inside of you and then you pee it out, which is the same logic behind lunchtime lipo.  Of course there have been cases of something collecting and collecting bacteria in one spot and then causing serious complications with lunchtime lipo to say the least, one woman being completely horrified because when she called to complain about a lump sticking out of her stomach, they said it was a good thing. 

That being said, there are some people who would believe in fat burning body wraps.  They heat up your body, and at higher temperatures at least theoretically your body burns more calories and more fat.  The problem is more that while you may be losing weight, you have to question what kind of weight it is.  It’s fairly quick yes, but all the weight is water weight.  Your body is heating up and water weight is being eliminated naturally speaking. 

So in so many ways it’s like a diuretic.  The weight will come back once you drink more water, it’s really quite simple.  Still, if your problem is a buildup of water weight that is actually unhealthy and unnecessary, you could drink more water.  That’s the healthiest way to flush it out.  But there are various options in general.
