Public Health

When you are a weight loss doctor, your friends and colleagues cannot help but comment on your work. Many conversations contain the question, "Isn't it all just....(carbs, laziness, fast food, inactivity, genes, fructose - fill in speculation here). I began to avoid the subject of my job like it was my dirty secret, but it came up fairly regularly nonetheless. Of the many completely wrong-headed things that non-obese people wonder, the one that came up most often was, "how does a  person let themselves get that way?"

A study of nearly 1,000 teens found that sexually active obese adolescents were significantly less likely to use contraception than normal weight peers, putting them at higher risk of unintended pregnancy. Obese adolescents who did use contraception were also less likely to use it consistently, according to the paper. 

Researchers analyzed 26,545 weekly journal surveys measuring sexual practices and contraceptive use from a longitudinal study of 900 women ages 18-19 in Michigan. They examined the association between weight and sexual behaviors.

Most Americans have never heard of it, but according to new federal data, sepsis is the most expensive cause of hospitalization in the US.

A vegan diet remains controversial because it is in defiance of our evolutionary mandate - it is unnatural in humans to only eat meat the same way it is in cats.

But diets are popular for lots of reasons that defy scientific explanation and regardless of the evidence basis, they work. People who eat all meat, for example, lose weight, and people who eat only animal products lose weight. In most cases, it is because people who go on any diet tend to live healthier in multiple ways but a new review of 12 studies determined that people on a vegan diet lose around two kilograms more in the short term than dieters on a normal plan.

If you ask some people why they would never want to get divorced, they joke that they would not want to have to 'get back down to dating weight', but do married people really give up and get heavier?

We can blame smartphone alerts, constant connectivity and a deluge of media for sleep deprivation but that is talking about the symptoms rather than the disease. The root cause is instead the thing that has led to cultural and social improvements for over 100 years - artificial light.

When it comes to educating the public about all matters chemical, there is no one better than Dr. Joe Schwarcz, a wildly popular professor at McGill University in Montreal. "Dr. Joe," as his students call him, is one sharp dude. He has written about 20 books, given countless lectures, been on TV and radio hundreds of times, and even hosts his own weekly radio show.

In 2011–2012, the most recent years for which finalized data were available, public health officials from 32 states and Puerto Rico reported 90 recreational water–associated outbreaks to CDC's Waterborne Disease and Outbreak Surveillance System (WBDOSS) via the National Outbreak Reporting System (NORS).

Searching for the perfect equation

You can discuss obesity and weight loss without using the same way you can discuss Astronomy without using math. While there may be a way to present a conjecture in either field using just logic and pure reason, math becomes necessary as the questions tackle more complex and defined aspects of the science. The mathematical regulation of body weight is easy understand and comes directly from a simple energy balance equation with “R” equaling the amount of weight gain or loss, based on calories in, “I”, minus calories expended, “E.”

The acidity of urine -- as well as the presence of small molecules related to diet -- may influence how well bacteria can grow in the urinary tract, a new study shows. 

Urinary tract infections (UTIs) often are caused by a strain of bacteria called Escherichia coli (E. coli), and doctors long have relied on antibiotics to kill the microbes. But increasing bacterial resistance to these drugs is leading researchers to look for alternative treatment strategies.
