People will try just about anything if they think it can produce easy weight loss, so it shouldn't surprise you that some advocate extreme measures like working out covered in cling wrap. The truth is, this won't provide easy weight loss -- or any real weight loss at all. If that's not enough to turn you off the idea, also know that exercising in cling wrap can be dangerous.
Wrapping your body in cling wrap when you exercise will increase your perspiration. This can cause weight loss, but there's a big catch -- this weight loss is from water loss, not fat. According to Columbia University, this weight loss will only be temporary; as soon as you rehydrate, your weight will return to normal.
Furthermore, wrapping your body in cling wrap can be dangerous as it doesn't allow sweat to evaporate and cool your body. This can cause your body to reach unhealthy temperatures and may be deadly. To lose fat, you should engage in moderate exercise and reduce your calorie intake. A safe calorie deficit of 500 to 1,000 calories a day will yeild weight loss at the rate of one to two pounds per week.
