Exercise and weight loss, how much?

From this article this quote: Exercise: The News You Don't Want to Hear

“A much better and more efficient way to exercise -- and one that research is clearly showing works a lot better -- is to do high-intensity circuit training. Put the beauty bells down and lift some iron. Shorten your rest periods. If you're doing "aerobics," do some interval training where you sprint for a while then jog to catch your breath.

And by the way, forget about "toning." It doesn't exist. You're either building muscle, maintaining the muscle you already have, or your muscles are slowly shrinking. The first two are accomplished with weight that's heavy to lift. The third is accomplished by doing nothing.

Lose weight by lifting weights

Strength training can have a positive role in fat loss. If one goes on a diet with significant caloric restriction the body's response of self preservation is accomplished by lowering it basal metabolic rate. The body does this by catabolizing lean body mass. The weight loss will be both fat and muscle. If one strength trains the body receives the message that lean body tissue is vital to survive the demands placed on it. Rather than losing lean body mass the body preserves it and adds to it.

From Men's Health magazine article 5 Reasons You're Not Losing Weight:

Burn calories four ways with strength training

Strength training helps you burn calories four ways:

1. Calories burned after the exercise stops. Excess Post-exercise Oxygen Consumption (EPOC) occurs after the workout. After running your body replenishes sugar stores. Strength training produces a larger post-exercise calorie demand as the body replaces sugar and rebuilds muscle as a result of the micro-trauma that has been imposed on the muscles.

2. Added muscle burns additional calories. Muscle is metabolically expensive to maintain and will require calories 24/7.

3. The workout itself. All forms of exercise burn calories, but not really as much as people think. Those who exercise with lesser intensity will burn less calories that those who exercise with more intensity.

 

Obesity epidemic may threaten mitten industry

From this Science Daily article comes this interesting headline: Obesity epidemic may threaten mitten industry.

Researchers found that fat people generate more heat. Thermograms (see picture) found that obese people dissipate more heat than normal through the hands and less heat than normal through the torso. They speculate that the feet would be another area for venting excess heat.
