Here's a diet tip that is certain to work: Eat nothing and drink nothing except water from 6 PM until you wake up the next day. With no dieting at all, you are certain to lose weight unless you go out of your way to eat three Big Macs at dinner.

The reason is because your other organs and your brain start communicating - and many of them get a break from constantly processing food. 

Studies have found that mice who accumulated the most glycogen in the liver did not gain weight in spite of having access to an appetizing diet. In addition to observing that those animals ate less, researchers have found that the brains of the animals showed scarce appetite-stimulating molecules but rather many appetite-suppressing ones.

In America, it is no surprise to see obese people. They know they are obese, they just don't care. In Britain, you see just as many obese people, but they don't care because they don't think they are obese. They don't even think they are 'very overweight'. 

Fewer than 10 percent of clinical obese Brits think they have a weight problem.

In results from a 2012 survey of around 2000 adults published in
BMJ Open, only 11 percent of obese women acknowledged they were "obese", with most describing themselves as "very overweight" or "just right".  At least they know those positive body image campaigns are working. 

If you like coffee, here is a delightful taste of confirmation bias. If you usually make fun of epidemiology, put your skepticism back in the pot, because coffee reduces diabetes.

As many as 380 million people worldwide have diabetes, with an economic estimate of up to $548 billion, making it one of the most significant global health problems in terms of pretend money no one earned. 
The Institute for Scientific Information on Coffee (ISIC) has brewed up its annual diabetes report outlining the latest research on coffee and type 2 diabetes and its delicious news. 

The research round up report concludes that regular, moderate consumption of coffee may decrease an individual's risk of developing type 2 diabetes. Key research findings include:

We may talk about a battle of the sexes when it comes to our species, but in the rest of the primate world, it really is a battle. We have the luxury of cultural hand-wringing about the shirt a Rosetta mission engineer wore in a YouTube video, but when it comes to chimpanzees, a shirt is the least of female problems.

Male on female violence among chimpanzees is frequent - and it has to do with sex. 

Frightening experiences stick with us but a new study finds that the bonding hormone oxytocin inhibits the fear center in the brain and allows fear stimuli to subside more easily. 

With over one billion people worldwide using social media, including 80 percent of employees using private sharing sites at work, members have been scrambling to insist that not only does it not negatively affect their work performance, but that it improves it. Yahtzee! probably wishes they could get the kind of free public relations Twitter gets.

Few studies have been done to examine the issue. Postdoctoral Fellow Dr. Cecilie Schou Andreassen and colleagues at the University of Bergen looked at the consequences of the use of social media during working hours.
