A laboratory study on rats found that the animals that breathed Beijing's notoriously polluted air gained weight and showed sighs of cardio-respiratory and metabolic dysfunctions after three to eight weeks of exposure.
Our perception does not always reflect reality, as evidenced by numerous studies. The information sent by the eyes to the brain is processed and contains many short-cuts and assumptions which makes things more optimized, but also leads to biases. One study, for instance, found that people who are overweight will judge an object as being farther than it really is. This suggests that physical characteristics -- people who thought they were overweight, but weren't in fact, did not share this bias -- plays a major role in defining perception.
Throughout our hunter-forager days, humans have developed a subconscious urge to over-eat and became less and less psychologically equipped to avoid obesity, especially during the winter months, a University of Exeter study recently found.
The fatty acids in fish oil have been proved to help with a wide range of conditions, with WebMD detailing benefits ranging from improving the health of the heart and circulatory system all the way to fighting dyslexia, kidney disease and improving your child's IQ. Now, scientists from the Kyoto University found that feeding fish oils to lab mice made them gain considerably less weight than their fish-less counterparts.
Obesity rates have increased virtually everywhere in the world, especially in the developed world. Some 160 million Americans are obese or overweight. Over 70 percent of all men and 60 percent of all women from the US are overweight, and it seems like the next generation will have similar problems: nearly 30% of boys and girls under age 20 are either obese or overweight, up from 19% in 1980. When talking strictly about obesity, one-third of American men (32%) and women (34%) were obese in 2013 compared with about 4% of Chinese and Indian adults. Being obese puts you at risk of developing a myriad of conditions from heart disease and stroke, to diabetes, to some cancers, to osteoarthritis. Yet, for all the hazards that being overweight causes most people would rather lose weight to appear more attractive, than be more healthy. The two are interlinked, as we shall see. But that's better than not having any reason at all to lose weight, and now a new study quantified just how much weight men and women need to lose for this to show and make them look more attractive. Some might find the findings useful.
Exercise is good for you, we all know that. Even better with drugs.
Low and middle-income countries bear the most deaths associated with sugary drink consumption. About 3 out of 4 deaths related to drinking sugary drinks happen in developing countries. These drinks greatly contribute to obesity, which in turn is associated with Type 2 diabetes, cardiovascular disease and cancers of the breast, colon, esophagus, gall bladder, kidney, pancreas and ovaries.
The Center for Science in the Public Interest, a nonprofit health advocacy group based in Washington, DC, just released its Xtreme Eating Awards. Hint: it's not that kind of award you want to win or even get mentioned. CSPI officials ranked the highest calorie, fat-rich meals served in restaurants across the country. This year, they say, they've been completely blown away by what they found on the table served to Americans.
It's no secret that TV food commercials stimulate pleasure and reward centers in the brain, after all advertisers wouldn't pay big money for them to air if they didn't entice people to order more. In fact, food advertising has increased dramatically over the past 30 years. Teenagers are exposed on average to 13 food commercials on any given day. At the same time, childhood and adolescent obesity in the US has been on the rise fast and worrisome, so we can't help but notice the connection. Now, researchers at Dartmouth found overweight teens are disproportionately affected by TV food commercials, as key brain regions that control pleasure, taste and - most surprisingly - the mouth are all much more stimulated than those teens with less body fat. The findings are important since they suggest overweight teens exposed to this kind of environment will experience further difficulties when they try to lose weight. A further insight is that dietary plans should also target subsequent thinking concerning eating food, not just the temptation.
Mice that had gut bacteria transferred from other mice fed with a high fat diet changed their behavior in a negative way, exhibiting anxiety or impaired memory. The findings suggest that apart from heart disease and stroke, obesity might put people's mental health at risk as well.
The topic of obesity inspires quite a bit of discussion, as well it should. The claim that North America is currently experiencing an obesity “epidemic”, a claim oftentimes mentioned by the media, is not hyperbole. Indeed, weight management has become such a global issue that the World Health Organization (WHO) has also termed the problem […]
A study conducted on a small number of men concluded that the "love hormone" oxytocin may reduce appetite, helping men lose weight.
It's increasingly hard to eat less sugar, as market shelves are filled with sugary products. In the past ten years alone, global sugar intake has risen by ten percent. In what's not the first and surely not the last appeal of the sort, the Wold Health Organization reports adults and children from the Americas to Western Europe and the Middle East must halve their daily sugar intake to reach acceptable levels. Otherwise the risk of obesity and tooth decay, to name a few, will skyrocket. In terms of daily energy intake, the new guidelines means that people should keep sugar at a maximum of 10% of equivalent energy.
A new study suggests that two very common emulsifiers - chemicals that stabilize foods and stop products like mayo from separating - could increase the risk of obesity and irritable bowel syndrome.
In the developed world, obesity is one of the biggest health concerns, so weight loss is one of the hottest topics today. But while dietary supplements and gastric by-pass surgeries are becoming more and more popular, we are also starting to discover issues associated with these procedures. Recently, a study published in Cell showed that the new generation of weight loss drugs may actually favor cancer development.
It’s painfully true by this point that we have a global obesity problem. Over the past 20 years, obesity rates have more than doubled, now including over a billion adults. The World Health Organization (WHO) has now released its global report card on obesity. See what countries are “in red” below: The first thing you […]
Nutritionists have identified pizza as a major contributor to obesity among young children and adolescents, and caution parents to be extremely careful considering the prevalence of the food stuff. One of the world's favorite snack is very rich in saturated fat, sodium and calories and, in the US, one in five children eat pizza on any given day. Fast food pizza is considerably more rich in calories than cafeteria pizza.
Obesity is a huge problem in the developed world, with some places worse off than others (i.e. the US). There are a slew of environmental factors that contribute to obesity, like eating unhealthy, hectic work schedules, genetics and so on. Researchers at University of California have a different hypothesis in mind that explains why people overeat. […]
A senate panel interviewed Dr. Mehmet Oz on Tuesday regarding his claims of various ‘miracle’ weight loss cures; as a result of lack of any scientific evidence and a big cloud of suspicion was floating above his head, Oz admitted that there is no actual evidence behind his proposed products. Obesity is the biggest health […]
A study has concluded that if obesity is thought of as a disease instead as a problem related to diet/lack of exercise, people will continue to eat high calorie foods. On June 18, 2013, the American Medical Association officially recognized obesity as a disease. This was met with mixed opinions, but the largest US medical […]
There’s been a lot of talk about obesity and what it really is, especially after the American Medical Association recently declared it a disease. Personally, I don’t agree with this idea. I’m no doctor, but it’s pretty clear that you can be obese without being sick in any way – so it’s pretty hard to […]
Researchers at Penn State College of Medicine studied the eating habits of overweight women during pregnancy, and found that those who expressed an “eating for two” were more likely to gain excessive weight, which contrary to what some may think is not recommended in their condition. Overweight is defined as having a body mass index of […]
The world is changing awfully fast, and with change expect many paradigms to shift or crumble entirely to dust. Over the course of a mere couple of decades, world’s politics has changed dramatically. Superpowers have fallen, the Cold War is well behind us and countries which not long ago were considered hallmarks of poverty have […]
A new study found that parent stress is linked to heightened weight gain in children. The causes of this aren’t very clear yet, however scientists advise interventions should focus on how to support families in challenging conditions. Researchers at St. Michael’s Hospital in Toronto studied data collected during the Children’s Health Study, one of the largest and […]
It’s surprising to me that this has to be said, but … oh well. If you are obese, you’re unhealthy. Even if you have normal blood pressure, cholesterol and blood-sugar, you’re still unhealthy. A study, published in the Annals of Internal Medicine, concluded that so-called “healthy obesity” was a myth. “Healthy obesity” or “benign obesity” […]
Previously, it’s been shown that obesity can cause changes in the brain, leading some people to over eat food high in saturated fat and refined sugar, as well as cause poorer memory. A new study published by researchers at University at Buffalo found a new physiological trait that can become altered as a result of obesity. […]
Despite all the related problems which contribute to obesity such as stress , the main cause is… eating too much. Recent studies have shown that people tend to overeat when they are stressed out – often creating a negative cycle of eating more, gaining weight and then getting stressed out about gaining weight – especially […]
After they identified precise groups of cells in mice brain that induce eating and others that curb it, a team of researchers caused full mice to continue eating and hungry mice to stop eating simply by stimulating one of these areas. Their findings could aid in the development of novel drugs that target eating disorders […]
Counter the popular dictum “out of sight, out of mind”, Kerri Boutelle, professor of psychiatry and pediatrics at University of California, San Diego’s School of Medicine, wants to tackle junk food addition in a novel way. In her experiments, she instructs overweight kids to stare at foods like french fires or cheetos in order to overcome their […]
Western society is becoming ever sedentary, as more and more jobs have transitioned to the office and technology offers people all kinds of comfortable reasons not to leave their homes. It’s well documented how a sedentary lifestyle can affect health, exposing the body to a slew of diseases, still a careful assessment of sedentary energy […]
I always find it funny when something says “zero fat”, but has tons of sugar in it. Sugar is addictive, it’s teeming in your cereal, it’s in your soda, it’s almost everywhere – and we need to get off of it; not to say we shouldn’t eat any sugar, but we really need to lower […]
I really liked New York’s mayor Bloomberg campaign of limiting sugary drink consumption, but that didn’t really work out as good as we were hoping. Another, better idea that has a lot of potential however is conveying the food’s calories into walking. So a regular burger would give you some 250 calories, which you can […]
Researchers looked at data that described people involved in car accidents and, after balancing factors like airbag and seat belt, found that obese people are at a much greater risk of dying during a collision than people of normal weight. The study holds a rather important significance since it might prompt car manufacturers to rethink […]
There are a number of factors that lead to obesity, the most obvious of which is of course eating too much, without burning the excess fat by exercising. Fact is, there are some people in the world who no matter how much they’d eat, they never seem to be satisfied, constantly consumed by a sense […]
The latin phrase “mens sana in corpore sano” has been put to the test by researchers who wanted to study what kind of repercussions an unhealthy lifestyle has on the mind. What they found was a dramatic increase in brain damage and dementia cases among subjects who have experienced high blood pressure, diabetes, smoking and obesity […]
Due to the rising of the phenomena, there has been a surge in the studies concerning obesity; there are, of course, a significant number of factors which affect it, and the number continues to grow each month. This time, it’s bottle feeding. Obesity in babies Researchers from the Center for Obesity Research and Education at […]
According to a recently published study reported by Swedish scientists, people who are obese and middle aged are up to four times more likely do develop dementia than people of normal weight. Published in the journal Neurology, the research was conducted 8,534 Swedish twins over the age of 65, of which data showed that 350 […]
According to a research conducted by anthropologists from Arizona State University, there seems to be a big increase in the general negative attitude people living in diverse societies have towards obese individuals. The study was made on 680 correspondents across 9 countries who were asked to agree or disagree with various statements expressed by scientists […]
Obesity is a condition that affects a significant portion of people throughout the world; as a result, a whole industry of “get rid of obesity” emerged, each offering its own “unfailable” method that just has to work. However, until now, nobody conducted a extremely thorough study to pinpoint exactly what you have to do to […]
According to a research conducted by researchers from the Cornell University the portions and the plates depicted in more than 50 paintings of the Last Supper have gotten bigger as time passed – way bigger. This finding seems to obviously suggest that as time passes, we eat more and more, which should raise some concerns; […]
Obesity is a problem that’s taking bigger and bigger proportions (especially in the US), due mostly to fast food and lack of physical activity, and it seems that most people still fail to understand the major bad impact it has on one’s health. However, thanks to a recent study published in the February 2010 issue […]
A recent study conducted by the U.S. Centers for Disease Control and Prevention shows that obesity related disorders account for ~10% of the total medical spending in the U.S. or, money-wise, approximately a whooping $147 billion. The study continues on stipulating that obese individuals spend 40% more on medical treatment than those of normal weight, […]
Whether you want to admit it or now, the world (and most of all America) has a problem with obesity. The fact that people are eating less healthy and working out less is something that can’t be denied even by the most optimistic of us. However, even taking into consideration all those aspects, the numbers […]
