Americans believe obesity is the
biggest health threat in the nation today – bigger even than cancer. But though
research shows that diet and exercise are insufficient solutions, a majority
says fat people should be able to summon the will power to lose weight on their
own. The findings are from a nationally representative survey of 1,509 adults
released on 1 November by the National Opinion Research Center at the
University of Chicago, an independent research institute. The study, funded by the
American Society for Metabolic and Bariatric Surgery, found that concerns about
obesity have risen. Just a few years ago, in a more limited survey, cancer was
seen as the most serious health threat. Researchers say obesity, which affects
one-third of Americans is caused by interactions between the environment and
genetics and has little to do with sloth or gluttony. There are hundreds of
genes that can predispose to obesity in an environment where food is cheap and
portions are abundant. Yet three quarters of survey participants said obesity
resulted from a lack of will power. The best treatment, they said, is to take responsibility
for you, go on a diet and exercise. Obesity specialists said the finding went
against evidence about the science behind the disease. It’s frustrating to see
doctors and the general public stigmatizes patients with obesity and blames
these patients, ascribing attributes of laziness or lack of willpower. Among the
survey participants, 94% had tried to lose weight with diet or exercise, to no
avail. A quarter of those people said they had tried five to nine times, and
15% said they had tried more than 20 times. Trying 20 times and not succeeding –
is that lack of willpower, or a problem that can’t be treated with willpower.

Frequent Facebook Users More Likely To Live Longer
As our social lives have moved onto
social media sites like Facebook over the past decade, there’s been a lot of
hand wringing over what all that screen time might be doing to our health. But according
to a new paper; time spent on social media could be associated with a longer
life. The paper, published in the journal PNAS on 31 October asserts that the
health effects of active online social lives largely mirrors the benefits of
busy offline social lives. Researchers find that people with more friends
online are less likely to die than their disconnected counterparts. This evidence
contradicts assertions that social media have had a net-negative impact on
health. The study’s methods were approved by three university and state review
boards, but skeptics will more that Facebook itself was closely involved with
it. Researchers have something’s in writing that they couldn’t interfere with
the publication of the research no matter what the result was. They noted,
though, that some at the company had been “pretty confident that they were
going to find this result. The research confirms what scientists have known for
a long time about the offline world: People who have stronger social networks
live longer. The study was based on 12 million social media profiles made
available to the researchers by Facebook, as well as records from the
California department of health. It found that “moderate use” of Facebook was
associated with the lowest mortality rate, and that receiving friend requests
correlated with reduced mortality, but that sending friend requests did not. The
paper fond that people with large or even average social networks lived longer
than people who had very small social networks. The paper itself acknowledges
the study’s “many limitations,” saying that Facebook is unique among social
media websites and that its data might not be more broadly applicable. It also
points out that its findings represent a correlative relationship as opposed to
a causal one: There is no evidence in the paper that using Facebook has any
direct effect on a person’s health.
