text: 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. \nSweating during normal workouts is alright but then a target weight loss of more than 2 kgs per week in unsupervised condition is dangerous.\nSo as a matter of precaution, no matter how quickly you want to lose weight don't ever wear a plastic body suit.
