text: will u lose more weight if u wear a plastic sweat suite while workingout,is it true the more u sweat more lost   technically yes, but this can be dangerous because excessive weight loss due to sweating alone can make you dehydrated which can cause a lot of health complications because with sweat you lose essential body salts also - minor problems can be cramps, fainting, weakness and major can be a toll on your kidney and your beauty if your skin sags.  sweating during normal workouts is alright but then a target weight loss of more than 2 kgs per week in unsupervised condition is dangerous. so as a matter of precaution, no matter how quickly you want to lose weight don't ever wear a plastic body suit.
