Sweating Calories
August 7, 2007


Thirty-five hundred calories - whether burned or consumed -- equals one pound.

Clinical Dietician Jeanne Struve says that we head to the gym or the track and break a sweat, but does how much we sweat have anything to do with how many calories we’re really burning?

“I think a lot of times people think that because they are sweating they are burning calories. So they have been out and maybe taken a walk and maybe sweated more so now than they did a few months ago so they think they have burned more calories so they can eat more and that is not the case at all.

Jeanne also says that sweating can vary depending on how fit you are. Believe it or not, fitter people sweat sooner and more than unfit people. How hydrated you are and the outside temperature and humidity also affect how much you perspire. “That is your body’s mechanism for cooling. So when you sweat your body needs to be cool so it brings the water out to cool.”

Wellness Center exercise specialist Heather Sines says that one important factor if you want to lose weight is to get that muscle burn, not necessarily to break a sweat. Two ways to really feel the burn are aerobic exercise, or cardio, and the other is aerobic exercise – or weight lifting. “If your doing anaerobic it can be strength training and you’re going to burn calories but it depends if you’re big, if your little it depends on your body composition because you can burn calories either way.”

So remember, if you want to really lose weight you want to lose body fat, not muscle or water weight.

Keeping hydrated while working out is important but if you jump on that scale too soon after your workout you might see the extra water weight register on the dial.
