BMI Versus Eyeballing

It used to be that to determine how fat a person was one took calipers and took anywhere from three to seven measurements of the body, came up with a total, and looked at a chart that took age into account to come up with a number for body fat percentage.  That might that a few minutes or a little longer if you did as recommended and checked it twice to make sure. 

Now BMI is the preferred measurement.  Take weight and height and look at a chart – you’re done, let’s golf. 

In his prime fighting weight Mike Tyson was 5’10’ and 220 pounds.  According to BMI charts Mike's BMI of 31.6 would classify Mike as clinically obese.

How much does added muscle increase metabolism?

A number often bandied about is that an additional pound of muscle will burn 50 calories a day. What about already existing muscle? Wouldn't that muscle also burn 50 calories a day too? The 50-calorie-a-day number can’t be true if one makes the assumption that the muscle tissue you all ready had before adding that pound of muscle will produce the same calorie burn - i.e.

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.

Thin People May Be Fat On The Inside, Doctors Warn; Exercise Is Key

From this article Thin people may be fat on the inside, doctors warn; exercise is key comes this quote:

“Some doctors now think that the internal fat surrounding vital organs like the heart, liver or pancreas - invisible to the naked eye - could be as dangerous as the more obvious external fat that bulges underneath the skin.
