From BBC Health News.
Given that obesity is becoming a world wide epidemic, and kills more people than the bird flu, this can be a helpful tool.
Scientists say they have developed a 3D scanner that can accurately determine if a person is truly obese.
Currently, doctors gauge fatness with a calculation of body mass index (BMI). But BMI is flawed – people with lots of muscle are considered overweight.
Instead of relying on weight and height measurements, as BMI does, the scan takes into account body shape and how much fat a person carries.
Birmingham’s Heartlands Hospital has been testing this Body Volume Index.
Muscle or fat?
One human guinea pig who has tested the BVI scanner is 19-year-old rower Ashley Granger.
He is 6ft 2ins (1.88m) tall and according to his BMI of 28 is at the top end of the overweight category, borderline obese.
Muscle weighs more than fat does. And you can hide away fat but be quite thin looking

His BVI scan correctly showed that he carries very little fat and that his weight is largely down to muscle.
Fitness trainer Matt Roberts said: “Muscle weighs more than fat does. And you can hide away fat but be quite thin looking.
“So it’s important that we don’t just use BMI alone.”
Dr Asad Rahim, a consultant in the obesity and endocrinology department at Heartlands Hospital, explained the work they had done with the BVI scanner over the last two years.
“We have completed the patient evaluation stage and are currently assessing the results.
“The scanner has certainly helped motivate some patients to manage their weight more effectively but there are also patients who were not scanned who lost weight.”
The next phase of testing has now been launched – the plan is to scan at least 20,000 people over the next two years as part of the Body Benchmark Study.
Select Research, the company which makes the scanners, said it hoped to make them available to GP surgeries at an “affordable” cost.
Fresh from my e-mail, an Irish joke. Heard it before, but didn’t see this coming!
An Irish woman of advanced age visited her physician to ask his help in
reviving her husband’s libido ..
“What about trying Viagra? asks the doctor .
“Not a chance”, she said . “He won’t even take an aspirin” ..
“Not a problem”, replied the doctor . “Give him! an “Irish Viagra” . It’s
when you drop the Viagra tablet into his coffee . He won’t even taste it . Give it a try and call me in a week to let me know how things went.”
It wasn’t a week later that she called the doctor, who directly inquired as
to progress . The poor dear
exclaimed, “Oh, faith, bejaysus and begorrah! T’was horrid! Just terrible,
“Really? What happened?” asked the doctor
“Well, I did as you advised and slipped it in his coffee and the effect was
almost immediate . He jumped straight up, with a twinkle in his eye, and with his pants a-bulging fiercely! With one swoop of his arm, he sent the cups and tablecloth flying, ripped me clothes to tatters and took me then and there, took me passionately on the tabletop! It was a nightmare, I tell you, an absolute nightmare!”
“Why so terrible?” asked the doctor, “Do you mean the sex your husband
provided wasn’t good”?
“Twas the best sex I’ve had in 25 years! But sure as I’m sittin’ here, I’ll
never be able to show me face in that Starbucks again!”
