Insufficient Sleep Could Result
To More Calorie Consumption
A
study has linked obesity with not
sleeping enough.
In this study participants either slept
normally or slept only two-thirds their
normal time. During this period,
researchers looked at the levels of some
hormones which are important in
regulating food intake, as well as
overall food intake and activity levels.
Interestingly, the sleep-deprived group
consumed an astonishing 549 extra
calories per day, in comparison to the
well-rested group. Furthermore, this was
associated with higher leptin and lower
ghrelin, but this is more likely to be a
consequence of eating more, and not
necessarily what caused ...

Study
Finds Most Weight Loss
Supplements Are Not Effective
Many
people constantly seek the easiest
methods that they can find to lose
weight. For example, they tend to grab
the latest shiny magic pill in the
market to achieve weight loss. A study
conducted by an Oregon State University
researcher confirms that "no research
evidence exists that any single product
results in significant weight loss". In
fact, many of these weight loss
supplements have detrimental health
benefits. Researcher Melinda Manore
revealed that some of the products such
as green tea, fiber, and low-fat dairy
supplements can produce a modest weight

Daily
Brisk Walking Can Help Prevent
Obesity?
Scientists
know that 50% of obesity cases are
influenced by genetics, but can this be
overturned? In other words, even if you
have the doomed genes, can you still
have a healthy weight? Or no matter what
you do, will you put on the pounds? At
first glance,
the study suggests that a
one-hour brisk walk can prevent obesity.
The overall message coming out of this
study is that we don't have to feel
doomed with the genes we have, and a
little exercise goes a long way.
However, effects of this exercise are
limited and unfortunately don't
completely override the detrimental ...

were asked to make regular daily entries
regarding calorie intake, fat intake,

again rejected by the FDA to become the
second diet drug rejected in the same
week. The diet pill, Qnexa, was

Alarming
Results of Obesity in Teenagers
Study
Obese
teenagers will continue to put on more
weight as adults, according to a study.
This is especially concerning as the
statistics for obesity in the USA are
already alarming. One third of children
and teenagers are overweight, and two
thirds of adults are obese. Overweight
youngsters are becoming the norm, with
many 8 year olds weighing as much as the
average 12 year old. As these young
people hit puberty, their body shapes
change with more muscle being put on
larger bones as they grow. Young girls
start growing breasts and both sexes
tend to spend more time on less
energetic pursuits, passing a lot of ...

Active
Breaks During Prolonged Sitting
Improves Health
A
study confirmed that overweight and
obese people's health can improve if
they take frequent short breaks of light
or temperate intensity activity like
walking to interrupt long sitting
durations. This is because these light
activities help in keeping the glucose
and insulin levels under control even
after taking meals with high calories
level. Repeated spikes in blood sugar
are often associated with "poor health
outcomes, including artery stiffening
and cardiovascular disease". Larger and
recurrent spikes damage the artery and
vein walls increasing the vulnerability
to ...

Fructose
May Not Induce Weight Gain?
According
to a review and meta-analysis carried out by
David Jenkins of the University of Toronto and
his colleagues, fructose is no more a culprit in
weight gain than other carbohydrate types. While
fructose was associated with weight gain when
taken in high doses, it wasn't proven if the
excess weight was due to the fructose intake or
an overall high calorie intake. In fact,
according to a recent trial conducted by George
Bray of Pennington Biomedical Research Center in
La., extra calories do lead to an increase in
fat, no matter what the diet composition.

Do Brown
Fat Cells Hold the Key to
Eliminating Obesity and
Diabetes?
An
article appearing in Science
Daily reports that at the 93rd
meeting of the Endocrine Society
held in Boston, Aaron Cypress,
MD, PhD, reported scientific
findings which have lead
researches to believe that brown
fat in the human body may be
helpful in treating obesity and
diabetes.
Initially, it was believed that
brown fat cells were only
present in infant humans and
small mammals. Further studies
revealed that brown fat cells
are found in most adult humans
in an area extending from the
front of the neck to the chest.
However, the most recent studies
have revealed that brown fat
cells lie in areas of deep fat
in other regions of the ...

Long-Term Weight Loss Requires Almost
Double Suggested Amount
of Exercise
The
American
Heart Association (AHA) recommends at
