I think that a couple of people may care that there is yet another

human weight maintenance.

Yet another piece of scientific evidence that says that calories are
not the final word on fat storage or fat loss in humans.

Calories mean squat.

Huh? Over a six year period, a 5.4% weight gain effect could be easily
explained by different effects on muscle, exercise tolerance/predisposition,
sleep, or any number of things that would have meant the trans-fat group
burned fewer calories than the cis-fat group.

Kylie Kavanagh, at Wake Forest University Baptist Medical Center in
Winston-Salem, North Carolina, US, wondered how this "killer fat"
would affect the risk of diabetes in 51 vervet monkeys.

She fed one group of monkeys a diet where 8% of their daily calories
came from trans-fats and another 27% came from other fats. This is
comparable to people who eat a lot of fried food, says Kavanagh. A
different group of monkeys was fed the same diet, but the trans-fats
were substituted for mono-unsaturated fats, found in olive oil, for
example.

Both groups ate the same total calories, which were carefully metered
to be just enough for subsistence.

Path to diabetes
After six years on the diet, the trans-fat-fed monkeys had gained 7.2%
of their body weight, compared to just 1.8% in the unsaturated group.
CT scans also revealed that the trans-fat monkeys carried 30% more
abdominal fat, which is risk factor for diabetes and heart disease.

"We were shocked. Despite all our enormous efforts to make sure they
didn't gain weight, they still did. And most of that weight ended up
on their tummies," says Kavanagh, who presented her findings at the
American Diabetes Association meeting in Washington DC, on Monday.
"This is walking them straight down the path to diabetes."

This is the first study to show such a dramatic result on abdominal
fat, adds Dariush Mozaffarian at the Harvard School of Public Health in
Boston, US. "The days of thinking about fats just as calories are
over," he says.

Partially hydrogenated oils can easily be replaced by other oils during
food production. Last week, fast-food giant Wendy's announced that it
was cutting partially hydrogenated oils from its food in the US and
Canada, while in January, food manufacturers in US were ordered to
label all trans-fats on packaged goods.

Cherry picking now are we, Mr Chinnis?

I'm sorry, but you apparently forgot to include your point in your post.

I thought you might actually want to read all that was written and not
just cherry pick data points. I figured an MIT grad would catch that
point without having to have it spelled out.

TC

I had read the complete article already. Nowhere does it indicate that
sleep, exercise levels, muscle, etc. were the same in the two groups. The
trans-fats had an effect on something that reduced the use of calories. It
would be interesting to determine what that was.
