Brain activity and response to food cues differ in severely obese women
The brain’s reward centers in severely obese women continue to respond to food cues even after they’ve eaten and are no longer hungry, in contrast to their lean counterparts. The study compared attitudes and the brain activity of 15 severely obese women (those with a body mass index greater than 35) and 15 lean women (those with a BMI under 25).

Researchers show copper is essential for burning fat
Is copper deficiency contributing to the obesity epidemic? Though small amounts of copper are essential to health – oysters, liver, beans and nuts are good sources – copper’s role in metabolism has been unclear: Some studies found that it boosted fat burning, others that it depressed it.

Body fat can send signals to brain, affecting stress response
The brain’s effect on other parts of the body has been well established. Now, a group of researchers has found that it’s a two-way street: Body fat can send a signal that affects the way the brain deals with stress and metabolism. While the exact nature of those signals remains a mystery, researchers say simply knowing such a pathway exists and learning more about it could help break a vicious cycle: Stress causes a desire to eat more, which can lead to obesity. And too much extra fat can impair the body’s ability to send a signal to the brain to shut off the stress response.

Walking an extra two minutes each hour may offset hazards of sitting too long
Eat less, workout more, these are the messages we are being sent almost on a daily basis. But how do we quantify “more” and who really should listen to that advice? Well a new study suggests that engaging in low intensity activities such as standing may not be enough to offset the health hazards of sitting for long periods of time. On the bright side, adding two minutes of walking each hour to your routine just might do the trick.

Watch out Atkins: Over eating fatty foods can alter your muscle metabolism
More bad news on the obesity front and strangely enough, on the popular diet front too — at least for diets like atkins. New research shows that even short term high-fat diets can change your metabolism. So while you might think that you can get away with eating fatty foods for a few days without it making any significant changes to your body, think again.

It’s all hype: Few commercial weight-loss programs are effective
In a bid to help physicians guide obese and overweight patients who want to try a commercial weight-loss program, a team of Johns Hopkins researchers reviewed 4,200 studies for solid evidence of their effectiveness but concluded only a few dozen of the studies met the scientific gold standard of reliability.

High-fat diet causes brain inflammation and alters behavior
We hear in the media all the time, obesity is effecting our health. In most cases when we talk obesity we are talking about heart disease, sedentary activity, or chronic overeating. But what if a high-fat diet — regardless of obesity — has more than just an affect on your waistline? What if the consumption of fatty foods can change your behavior and your brain?

Is diet soda making you fat?
The diet soda controversy is still raging on, study after study has been coming in saying that it helps weight loss, it hurts weight loss, and frankly it can all be a little confusing. Well this probably won’t help matters any, a new study shows that increasing diet soda intake is directly linked to greater abdominal obesity in adults 65 years of age and older. These findings raise concerns about the safety of chronic diet soda consumption, which may increase belly fat and contribute to greater risk of metabolic syndrome and cardiovascular diseases.

High fat diet leads to brain inflammation and obesity
The stomach strikes again, or so it seems. We’ve already covered how your stomach seemingly controls your brain and your blood-brain barrier, but now it seems that what you eat –not too indirectly related to your stomach– might make you fatter, but not in the way you might be thinking thinking. What you are eating may be causing inflammation in the brain.

What makes us fat, OR food vs. physiology
There is a heir of mystery surrounding weight loss and fat in general. Have you ever heard you have all the fat cells you’ll ever have — that’s false by the way. Then there is fad diets like gluten free — proven to do nothing unless you actually have a diagnosed gluten allergy — or adkins, but now researchers believe they’re on track to solve the mystery of weight gain – and it has nothing to do with indulging in holiday eggnog.

Is Fat Making you… Fat?
Fast food, let’s face it, it’s not the best for you. Yet Mcdonalds and Pizza hut are known practically world wide [although menu options differ]. With the rise of our waist lines and the shrinking cost of fast food, you might suspect a connection. Fortunately for your big mac addiction [no judgement] it isn’t what you might think. If you’re finding it harder and harder to see your toes, you might just have your brain, and not your stomach, to thank for it.

Fighting the Obesity Epidemic with X-box [No, not that one]
Despite all the efforts, people are losing the war on obesity. There is probably a number of factors involved, genetics, underlying medical problems, most of all diet, but in any case we are living in a world that is slightly heavier than our historical counterparts. Maybe that’s why so many researchers are trying to find an easy way for people to better regulate their weight. Thankfully that goal is one step closer because researchers have found a protein that controls when genes are switched on or off, one that plays a key role in specific areas of the brain to regulate metabolism.
