I like to wear clothes made with Coolmax or DriFit. They are a very light polyester that wisk the moisture away from you skin. They keep you dryer, so you are cooler in the hot temps and warmer in the cold temps. (Wet clothes in cold temps could make you sick).

I also agree with the form fitting clothes. They prevent chaffing and provide extra support. If you're uncomfortable wearing tight clothes, you can always wear a looser layer over top.

Cotton can be the worst thing to wear, as you will be soaked when you're done. Cotton socks give my feet blisters on longer runs.

The truth is, if you are inducing a sweat by wearing more clothing, the only thing you are really doing is excreating more water. As soon as you start drinking again, the water will come back.. at the same time the induced sweating could exacerbate dehydration to dangerous levels.

Sweating is the bodies natural tendency to cool down, but it doesn't burn more calories..

Conversely, being cold, and your body's natural tendency to warm you up,,, burns 10 times the calories as being too hot. It's like swimming in a pool that is set under 75 degrees.. After the first lap, your body has generated enough heat from within that you don't feel the cold anymore. But just by being in the pool at that point, and your body's constant heat generation, will continue to burn calories.

Something else that I have learned about exercise clothing, that if you have skin folds that tend to rub together, it is recommended that you wear "form fitting" clothing, to prevent chaffing,, and wisk away the sweat from your body, that would otherwise cause a rash. Sweat contains all the poisons and free radicals that your skin is exposed to,, and many things that you would consume from just eating, drinking and breathing... so, by wearing clothing that "fits" it absorbs the sweat and poisons, and keeps them off the body, directly.

Give your skin room to breathe and sweat when you exercise. Cover up when you're finished, to prevent chill. I don't think covering up and sweating a little more does anything for caloric output. One is more likely to burn extra calories when one is cooler.

Get as comfortable as you can while you exercise. I use a T-shirt and sweat pants. Some people use shorts.

Keep it up. Exercise makes all the difference!

Good Luck!

Actually DR Atkins talks about calories burned for body temp as heat production in his book in the chapter 11 question about calories at the end. You are actually burning less calories staying hot while you workout since your body doesn't have to use as much energy to maintain your core temp and you risk over heating. You will lose weight sweating while you workout but it is water weight and will be replaced as you re-hydrate during the day.

Wear whatever you are comfortable in and dress in layers then as you heat up you can remove a layer and if you chill you can add a layer.

Another consideration is that if you make yourself uncomfortably hot you'll likely not work out as long. You benefit more from a longer workout obviously. My goal when I use a treadmill or go out to walk or run is to be as comfortable as possible so that I am feeling good and can extend the time I'm exercising.
