Getting too little sleep can have all kinds of negative consequences, including making you cranky and impairing your driving. A growing body of evidence suggests an addition to that list might be in order: Lack of sleep might also make you fat.
The intriguing prospect that sleep duration may play a role in how much we weigh has researchers busily conducting studies to tease out the potential relationship between shut-eye and BMI.
Although it might seem intuitive that under-sleeping leads to overeating, science hasn’t yet found a direct cause-and-effect relationship between lack of sleep and being overweight. “There is a very, very strong link,” says Jim Hill, director of the Colorado Nutrition Obesity Research Center at the University of Colorado and a spokesman for the American Society for Nutrition. “People with sleep problems tend to have obesity. Why? That’s where the research is.”
In one of the latest studies, Marie-Pierre St-Onge of the New York Obesity Nutrition Research Center at St. Luke’s-Roosevelt Hospital found that sleep-deprived people tend to burn the same number of calories — in her study, about 2,600 per day — as people who enjoy a full night’s sleep. But her research, published in the August issue of the American Journal of Clinical Nutrition, found that sleep-deprived subjects consumed about 300 more calories per day (2,800 vs. 2,500) than the well-rested subjects. Because it takes just 3,500 calories to add a pound to your body, St-Onge says, “if people kept that up for a while, it would add up really, really quickly.”
Still to be determined: Do sleep deficits actually cause people to become overweight? Or does being overweight cause people to not get enough sleep? Or might the two conditions share some underlying factor that’s not been found?
Michael Breus knows those questions need answers. But he’s not waiting for all the dots to be connected. Breus, a prominent sleep disorders specialist, has recently published “The Sleep Doctor’s Diet Plan: Lose Weight Through Better Sleep” (Rodale/Mindworks, 2011). As the subtitle suggests, he’s convinced that the body responds to too-short sleep by packing on pounds — and, conversely, getting more sleep is an effective weight-loss strategy. (Although the book touts Breus as the Sleep Doctor, he is a psychologist with a PhD, not a physician.)
Breus spells out (and supports by citing research) several means by which too little sleep could lead to weight gain. When you’re sleep-deprived, he says, your body moves into a different mode. “On a physical level, the key things are hormones,” Breus says. When you lack sleep, he explains, “your metabolism slows down. Your body is trying to conserve energy stores” to carry you through the longer period of wakefulness. That slowdown triggers the release of cortisol, a hormone that your body secretes in response to stress and that boosts your appetite: Your body senses it needs more energy, so it demands more food.
At the same time, Breus says, sleep deprivation causes your body to release more ghrelin, the hormone that signals hunger, and less leptin, the hormone that tells your body it’s full. When those hormones are out of whack, your body wants more food and lacks the sensitivity to know when to stop eating. Combined with the fact that you’re awake for more hours a day, that hormone cocktail can send you snacking into the wee hours.
A change in socio-economic status generally brings change in food habits, which then gets reflected in the changed disease profile. “Indian consumers are increasingly taking to packaged food due to accessibility, affordability and attractive marketing,” said Dr B Sesikeran, director, National Institute of Nutrition.
Addressing a conference on National Priorities in Nutrition Research here on Monday, Dr Sesikiran added, “The incidence of diabetes has nearly doubled among the rural population over the last decade which is more than that observed in the urban populace.”
A book of revised Dietary Guidelines for Indians, was released on the occasion, which reveals the increase in lifestyle-related diseases among both the urban and rural population.
Dr Sesikeran said the book meant for the general public, monitors the shifting profile of nutrition-related diseases over time. “The data presented indicates that the average blood pressure has increased in Indians due to increased consumption of processed foods and snacks,” said the director.
A new guideline has been specifically included about ‘regular physical activity’, keeping in mind the increasingly sedentary lifestyle being followed. The upper limit for Body Mass Index (BMI) which determines whether a person is considered obese has been lowered from 25 to 23, as Asians are at a higher risk of obesity and cardiac arrests at marginally high BMIs, he added.
However, the new-found affluence has failed to trickle down to those at the bottom, as the poor remain calorie-deficient and incidence of anaemia among children and pregnant women has increased.
�He said the book recommends an increase in fat intake by 20 percent than what it was in 1998. “The book also recommends increase in calcium intake for children and adolescents to 600-800 mg per day considering under-nutrition and stunted growth still prevails,” added Dr Sesikeran.
Three senior executives of Russian nuclear designer Gidropress, and two other significant figures in the Russian nuclear industry, died in an aeroplane crash with 40 other passengers on 21 June.
Among those killed were: Sergey Ryzhov, director and general designer of OKB Gidropress; Gennady Banyuk, deputy director and chief designer of OKB Gidropress; Nikolai Trunov, head of department and chief designer of OKB Gidropress; Andrei Trofimov, chief technology officer of nuclear component manufacturer OKBM Afrikantov; and Valery Lyalin, head of technology department at nuclear component manufacturer Atomenergomash.
The RusAir Tu-134 passenger jet from Moscow crashed as it neared its destination of Petrozavodsk airport in Russia’s northwestern republic of Karelia on 21 June.
The men were travelling to the ZAO Petrozavodskmash metal fabrication business, acquired by Atomenergoprom in February 2010, to attend a meeting about nuclear power plant component manufacture.
Short biographies follow (no information about Valery Lyalin was available by press date).

Whether or not you are in a hurry to reach the city’s Sahnewal airport, only a combine of dexterous driving skills and a gritty resolve, to negotiate the route lacking signboards amid haphazard traffic movement, is what can help you reach your destination.
For those coming from the heart of the city, an otherwise 20-minute journey, spread over 5 km, to the airport has become a 90-minute agony.
Tucked away in a sleepy village of Sahnewal, the airport is located on a deteriorating road that meets the National Highway 1, where the ongoing construction of the six-lane project has been affecting the average speed of vehicles. And, absence of traffic cops is making the things worse. What’s incredible is that there is only one signboard that announces the location of Sahenwal airport, and this is barely a few minutes from the place itself. So anybody who is not aware of the airport’s location would be left wondering about how to reach there.
(Reuters) – Microsoft Corp has demanded that Samsung Electronics Co Ltd pay $15 for each smartphone handset it makes based on Google Inc’s Android operating system as the software giant has a wide range of patents used in the mobile platform, local media reported on Wednesday.
Samsung would likely seek to lower the payment to about $10 in exchange for a deeper alliance with Microsoft for the U.S. company’s Windows platform, the Maeil Business Newspaper quoted unnamed industry officials as saying.
Samsung had no immediate comment.
In April last year, Microsoft said it had reached a licensing deal with Taiwan’s HTC Corp, under which it would receive royalty payments on its handsets running Android.
The move comes as Android phones gain in popularity. Microsoft charges handset makers such as HTC and Samsung to use its Windows mobile software and has tied up with Nokia to challenge Google and Apple Inc in the smartphone market.
Analysts forecast Samsung, the world’s No.2 handset maker, to have sold about 19 million smartphones in the April-June quarter, with the dominant position running on Android. It is widely expected to emerge as the No.1 smartphone maker, replacing Nokia’s more than 10-year reign.
Samsung’s Galaxy S II, successor to its flagship Galaxy S smartphone, which runs on the Android platform, has sold more than 3 million units since its debut in late April.
With the arrest of two CGHS employees, the police have busted a racket in which government medicines meant for the poor were sold on the open market for a hefty profit. The duo, employed at the CGHS Tilak Nagar dispensary as a pharmacist and assistant dresser respectively, used to siphon off costly medicines meant for government supply from the CGHS dispensary. The medicines were later sold at Bhagirath Place through a middleman netting the accused Rs 3 lakh a month. Police say this racket had been going on for the last 3 years.
A team from the Crime Branch, led by Inspector Arti and additional DCP Joy Tirkey, apprehended Anil Yadav (23) the absconding middleman on July 2. Yadav runs a chemist shop in Bhalaswa , Mukundpur, and was arrested from Bhagirath Place, Delhi’s wholesale drugs market.”When questioned Anil disclosed that a CGHS dispensary pharmacist named Ravinder Singh and Bacha Singh, an assistant dresser, had siphoned off CGHS medicines and given them to him for sale,” said DCP (crime) Ashok Chand.
Ravinder Singh (41), a resident of Rohini and Bacha Singh (48), a resident of Hari Nagar in west Delhi were later arrested at the same CGHS dispensary where they have been employed for the last 3 years. CGHS medicines worth more than Rs 3 lakh were also seized from them.
The police said these arrests came after a raid was conducted at a pharmacy and godown located at Jagsonpal Building, Bhagirath Place. Apart from spurious medicines, the cops also discovered stocks of medicines meant for use by CGHS, MCD, ESI and DGAFMS hospitals and dispensaries with stamps to prove it. Investigations further revealed that the medicines had stamps of different government agencies . These medicines were supplied by one Vickey, Anil and Naren, all of whom are absconding.
Their modus operandi was simple yet effective. “They adopted a dual method for siphoning of CGHS medicines from the CGHS dispensary. Firstly , they identified people they called ‘Sleeper’ CGHS employees. These employees never or rarely used their CGHS cards. Ravinder and Bacha wrote down the names of medicines they wanted on the prescription cards of these employees and got them approved by the doctors at the dispensary. After the prescription cards had been signed Ravinder simply indented them from the stock as he himself was the pharmacist. In the second module, they simply added some medicines to the other medicines written on the prescription cards of genuine CGHS cardholders . The medicines were then indented from the state.
Hardware firm IBM was declared the leader in the recently-released India’s Top Supercomputers list for 2011, compiled and published by Supercomputer Education and Research Centre (SERC), Indian Institute of Science. Of the 16 installations featured by SERC, IBM topped the list with six high-performance computing installations across India, a press release from the firm stated.
According to the survey, Bangalore leads the list in the number of supercomputers, followed by Chennai.
Seventy-six per cent of Indian firms find security a significant challenge to implementing server virtualisation, according to security firm Symantec’s 2011 Virtualization and Evolution to the Cloud Survey. One in two respondents also said security concerns reduced confidence in placing mission-critical applications on virtualised servers.
Furthermore, reduction in datacenter (storage) requirements was a goal for 93 per cent of the respondents, but reached by only 33 per cent, a release from the firm stated.
