Sweating and Fat Loss

I think there's much confusion about the role of perspiration/sweat in fat loss.  This has lead to several products (personal saunas, sauna suits, etc) which promise to help you "sweat off the pounds." 

Here's the truth:  weight loss caused by sweating is only temporary water loss.  As soon as you drink water, the weight you lost through sweating comes right back.

Boxers and wrestlers often wear plastic bags or sauna suits to make a specfic weight class.  The reason is simple:  dropping water weight is the quickest way to lose weight.  But there's only so much weight you can safely lose through prespiration--dehydration can be extremely dangerous.  Most boxers/wrestlers start drinking water/Gatorade immediately after their weigh-in so they can be hydrated before the match. 

Don't wear plastic or other products designed to induce sweat.  It does nothing to help with fat loss and only dehydrates you.
