Compared to a decade ago, fewer Americans have a cluster of risk factors that together can signal heart troubles and diabetes down the line, according to a new study.
But while so-called metabolic syndrome is declining, some of its components - including large waistlines and poor blood sugar control, which carry their own risks - are becoming more common, researchers found.

Researchers from the University of Bonn have treated mice with Viagra and discovered that the drug converts white fat cells (those unwanted denizens of the belly and similar swollen regions) into beige fat cells. Instead of storing excess energy, these recently discovered beige fat cells burn the energy from ingested food and convert it to heat. Viagra also appears (at least in mice) to decrease the risk of other complications caused by obesity.

1. The author has facts from scientific studies to prove that the case that 'Viagra could prove useful in the fight against obesity', The author has proven their case very effectively 2. This article explains that a drug may help in the obesity crisis. 3. It is a very interesting article with a rather odd topic.

In a review of almost 100 past studies covering nearly three million people, researchers found that being overweight or slightly obese was linked to about a 6 percent lower risk of dying, compared to people considered "normal weight."

The relevant idea from this article is not that being slightly overweight lowers risk of dying but that being obese or severely obes increases risk of dying by 18-29 percent. The cost of that risk is a major factor. Most of those will develop heart issues or diabetes which increases health care costs. There needs to be continuous education on the effect that obesity has on quality of life and healthcare costs--similar to the campaigns on smoking that are now second nature to most of us.

Approximately 68 percent of U.S. adults are overweight or obese, according to the National Cancer Institute, which puts them at greater risk for developing cancer, cardiovascular disease, diabetes and a host of other chronic illnesses.
But an international team of scientists led by Virginia Commonwealth University Massey Cancer Center researcher Andrew Larner, M.D., Ph.D., has successfully reversed obesity in mice by manipulating the production of an enzyme known as tyrosine-protein kinase-2 (Tyk2). In their experiments, the scientists discovered that Tyk2 helps regulate obesity in mice and humans through the differentiation of a type of fat tissue known as brown adipose tissue (BAT).
Ray and Terry's 's insight:
This discovery may lead to methods to treat obesity by modulating levels of the enzyme. If successful, not only would obesity rates decrease, but healthy life span would increase.

Vaccines and antibiotics may someday join caloric restriction or bariatric surgery as a way to regulate weight gain, according to a new study focused on the interactions between diet, the bacteria that live in the bowel, and the immune system.
Researchers examined the complicated relationship between the immune system, gut bacteria, digestion and obesity. They showed how weight gain requires not just caloric overload but also a delicate, adjustable -- and transmissible -- interplay between intestinal microbes and the immune response.

Earlier this year, a team from UC San Francisco reported on the discovery that a class of commonly prescribed type-2 diabetes drugs, called TZDs (thiazolidinediones, such as Actos and Avandia), promoted the conversion of energy-storing white fat cells into energy-burning brown fat cells. Now researchers at Columbia University Medical Center (CUMC) have identified the mechanism that causes this change to take place, potentially leading to new treatments for obesity and type-2 diabetes.
While it was known that TZDs have the ability to change white fat cells to brown fat cells by activating a cell receptor called peroxisome proliferator-activated receptor–gamma (ppar-gamma), the exact mechanism behind this transformation was unclear. Because TZDs have numerous adverse side effects,

The epidemic of obesity is well known. But how well do we understand the costs?
With an impact ranging from increased gasoline usage to wider public seats, the cost of obesity has been hidden. Many assume that health care is the budget that suffers the most. However, there are additional costs that will affect everyone.

LONDON (Reuters) - More people in developed countries are overweight or obese than ever before, dooming them to years of ill health, pushing up healthcare costs and piling more pressure on health systems,...
While obesity in some countries has stabilized, this is not true in the US and Canada. The cost is high. “Experts say severely obese people die on average eight to 10 years sooner than people at normal weight, with every 15 extra kg increasing risk of early death by around 30 percent.”

Chronic diseases linked to obesity and overconsumption of food are now a bigger global healthcare burden than illness and disease caused by malnutrition, according to the most comprehensive disease report ever produced on global health issues.
Ray and Terry's 's insight:
Moderate caloric restriction (reduce your daily caloric intake by 10-20%) can have numerous health benefits. Start by finding your target calorie intake to maintain an optimal weight. If you can stick to that daily level, reduce it by 10%.
Fasting is also beneficial. The easiest way? Stop eating at 6-7pm and don't eat again until 6-7am. With minimal effort, you have a 12 hour fast. Plus, you will sleep easier if your digestive system is at rest.

For the first time ever, diseases associated with obesity are now more of a global health burden the lack of nutrition. This investigation has been going for 5 years with over 50 scientists exploring the deep issues of obesity. I believe it's a personal decision too eat badly, don't do enough physical activity, drink to much, smoke to many cigars and just don't look after your body the way were meant to. Rising numbers of obesity has been increased with young adults over the years. The biggest global risks effecting people is high blood rate, which is also the biggest neglected global health in most countries. These scientists thankfully have put out antidotes that have helped save many millions of kids and adults from obesity. We really need more help like this in society, we need to team up and help out each other, were all human no one is special so don't be afraid to ask for help.

With health authorities saying the world is facing an obesity epidemic and with a recent major study finding that – for the first time – more people now die from obesity-related illnesses like heart attacks and strokes than malnutrition, scientists have been tackling the fat problem.
Recent approaches to this problem include looking at ways to slow down the biological clock and converting calorie-storing white fat cells into heat-generating brown fat cells. Now, a new study has found that linking two hormones into a single molecule could lead to improved treatments for medical conditions such as obesity.

Scientists have long suspected that metabolic disorders, such as type 2 diabetes and obesity, could be linked to our circadian rhythm or biological clock. For example, laboratory mice with altered biological clocks often become obese and develop diabetes.
Now biologists at UC San Diego have discovered that a chemical, which affects the activity of a key protein that regulates our biological clock, can repress the production of glucose by the liver, offering a promising new direction for the development of a new class of drugs to treat diabetes.
A team headed by Steve Kay, dean of the Division of Biological Sciences at UC San Diego, had previously found that altering the levels of a key protein, called cryptochrome – which regulates the biological clocks of plants, insects and mammals and also regulates glucose production in the liver – could improve the health of diabetic mice.
