Britain Says Equine Drug May Have Entered Food Chain





LONDON — A crisis over horse meat in European food products deepened Thursday when British officials said tests showed that a powerful equine drug, potentially harmful to human health, may have entered the food chain in small quantities.




Until now, the crisis had been seen primarily as an issue of fraud after products containing horse meat were labeled beef, with politicians insisting that, even if millions of products sold as beef contained up to 100 percent horse meat, food safety was not at issue.


But on Thursday came the first admission that a banned substance, phenylbutazone – known as bute – could have entered the food chain in horse meat.


The British Food Standards Agency said that it had checked the carcasses of 206 horses slaughtered in Britain between January 30 and February 7. “Of these, eight tested positive for the drug,” it said in a statement.


Because there is little demand for horse meat in Britain, the carcasses are thought to have been exported to France where they were likely to have been used by the meat industry. The British and French authorities were trying to trace the meat but as yet have not identified any products directly affected.


The scandal has already plunged the British food industry into crisis with millions of products being withdrawn from supermarket freezer counters, initially in Britain and Ireland. But other countries, including Sweden and Germany, have been affected too.


Officials in Britain tried to reassure the public.  "Horse meat containing phenylbutazone presents a very low risk to human health,” Britain’s chief medical officer, Dame Sally Davies, said in a statement Thursday.


"Phenylbutazone, known as bute, is a commonly used medicine in horses. It is also prescribed to some patients who are suffering from a severe form of arthritis. At the levels of bute that have been found, a person would have to eat 500- 600 100 one hundred percent horse meat burgers a day to get close to consuming a human’s daily dose,” she said.


“And it passes through the system fairly quickly, so it is unlikely to build up in our bodies,” she added.


"In patients who have been taking phenylbutazone as a medicine there can be serious side effects but these are rare. It is extremely unlikely that anyone who has eaten horse meat containing bute will experience one of these side effects."


The widening scandal began when beef products on sale in several European Union countries were found to contain horse meat. Suppliers have said that the questionable meat originated at processing plants in Romania.

Well: Life, Interrupted: Crazy, Unsexy Cancer Tips

Life, Interrupted

Suleika Jaouad writes about her experiences as a young adult with cancer.

Every few weeks I host a “girls’ night” at my apartment in Lower Manhattan with a group of friends who are at various stages in their cancer treatments. Everyone brings something to eat and drink, and we sit around my living room talking to one another about subjects both heavy and light, ranging from post-chemo hair styling tips, fears of relapse or funny anecdotes about a recent hospital visit. But one topic that doesn’t come up as often as you might think — particularly at a gathering of women in their early 20s and 30s — is sex.

Actually, I almost didn’t write this column. Time and again, I’ve sat down to write about sex and cancer, but each time I’ve deleted the draft and moved on to a different topic. Writing about cancer is always a challenge for me because it hits so close to home. And this topic felt even more difficult. After my diagnosis at age 22 with leukemia, the second piece of news I learned was that I would likely be infertile as a result of chemotherapy. It was a one-two punch that was my first indication that issues of cancer and sexual health are inextricably tied.

But to my surprise, sex is not at the center of the conversation in the oncology unit — far from it. No one has ever broached the topic of sex and cancer during my diagnosis and treatment. Not doctors, not nurses. On the rare occasions I initiated the conversation myself, talking about sex and cancer felt like a shameful secret. I felt embarrassed about the changes taking place in my body after chemotherapy treatment began — changes that for me included hot flashes, infertility and early menopause. Today, at age 24, when my peers are dating, marrying and having children of their own, my cancer treatments are causing internal and external changes in my body that leave me feeling confused, vulnerable, frustrated — and verifiably unsexy.

When sex has come up in conversations with my cancer friends, it’s hardly the free-flowing, liberating conversation you see on television shows like HBO’s “Girls” or “Sex and the City.” When my group of cancer friends talks about sex — maybe it’s an exaggeration to call it the blind leading the blind — but we’re just a group of young women who have received little to no information about the sexual side effects of our disease.

One friend worried that sex had become painful as a result of pelvic radiation treatment. Another described difficulty reaching orgasm and wondered if it was a side effect of chemotherapy. And yet another talked about her oncologist’s visible discomfort when she asked him about safe birth control methods. “I felt like I was having a conversation with my uncle or something,” she told me. As a result, she turned to Google to find out if she could take a morning-after pill. “I felt uncomfortable with him and had nowhere to turn,” she said.

This is where our conversations always run into a wall. Emotional support — we can do that for one another. But we are at a loss when it comes to answering crucial medical questions about sexual health and cancer. Who can we talk to? Are these common side effects? And what treatments or remedies exist, if any, for the sexual side effects associated with cancer?

If mine and my girlfriends’ experiences are indicative of a trend, then the way women with cancer are being educated about their sexual health is not by their health care providers but on their own. I was lucky enough to meet a counselor who specializes in the sexual health of cancer patients at a conference for young adult cancer patients. Sage Bolte, a counselor who works for INOVA Life With Cancer, a Virginia-based nonprofit organization that provides free resources for cancer patients, was the one to finally explain to me that many of the sexual side effects of cancer are both normal and treatable.

“Part of the reason you feel shame and embarrassment about this is because no one out there is saying this is normal. But it is,” Dr. Bolte told me. “Shame on us as health care providers that we have not created an environment that is conducive to talking about sexual health.”

Dr. Bolte said part of the problem is that doctors are so focused on saving a cancer patient’s life that they forget to discuss issues of sexual health. “My sense is that it’s not about physicians or health care providers not caring about your sexual health or thinking that it’s unimportant, but that cancer is the emergency, and everything else seems to fall by the wayside,” she said.

She said that one young woman she was working with had significant graft-versus-host disease, a potential side effect of stem cell transplantation that made her skin painfully sensitive to touch. Her partner would try to hold her hand or touch her stomach, and she would push him away or jump at his touch. It only took two times for him to get the message that “she didn’t want to be touched,” Dr. Bolte said. Unfortunately, by the time they showed up at Dr. Bolte’s office and the young woman’s condition had improved, she thought her boyfriend was no longer attracted to her. Her boyfriend, on the other hand, was afraid to touch her out of fear of causing pain or making an unwanted pass. All that was needed to help them reconnect was a little communication.

Dr. Bolte also referred me to resources like the American Association of Sexuality Educators, Counselors and Therapists; the Society for Sex Therapy and Research; and the Association of Oncology Social Workers, all professional organizations that can help connect cancer patients to professionals trained in working with sexual health issues and the emotional and physical concerns related to a cancer diagnosis.

I know that my girlfriends and I are not the only women out there who are wondering how to help themselves and their friends answer difficult questions about sex and cancer. Sex can be a squeamish subject even when cancer isn’t part of the picture, so the combination of sex and cancer together can feel impossible to talk about. But women like me and my friends shouldn’t have to suffer in silence.

DealBook: American and US Airways Announce Merger Agreement

8:53 a.m. | Updated

Ending a yearlong courtship by US Airways, American Airlines agreed to merge with the smaller carrier, paving the way for the creation of the nation’s largest airline.

The boards of the companies have unanimously approved the deal, valued at $11 billion, according to a news release on Thursday morning. A merger would bolster American’s domestic footprint, strengthen its presence in the Northeast and give it a bigger network to attract business travelers and corporate accounts.

Under the terms of the deal, US Airways shareholders would own 28 percent of the combined airline, while American Airlines shareholders, creditors, labor unions and employees would own 72 percent.

The merger would create a company with the size and breadth to compete against United Airlines and Delta Air Lines, which have grown through mergers of their own in recent years and are currently the biggest domestic carriers. The combined airline will have more than 100 million frequent fliers.

But while United and Delta went through bankruptcies and mergers in the last decade, American has been steadily losing ground while racking up losses that have totaled more than $12 billion since 2001. It was the last major airline to seek court protection to reorganize its business, filing for bankruptcy in November 2011.

The wave of big mergers in the industry has created healthier and more profitable airlines that are now better able to invest in new planes and products, including Wi-Fi, individual entertainment screens and more comfortable seats for business passengers. But some consumer advocates said they worried that reducing the number of airlines would lead to higher fares over the long run and allow airlines to increase revenue by imposing new or higher fees.

The deal, which was completed in recent days, could be formalized as American leaves bankruptcy. W. Douglas Parker, the chairman and chief executive of US Airways, would take over as American’s chief executive. Thomas W. Horton, chairman and chief executive of the AMR Corporation, American’s parent, would be chairman of the combined company, though his tenure could be limited.

“I have been a long proponent of consolidation in the industry,” Mr. Parker said on a conference call. “And this is the last major piece needed to rationalize the industry and make it profitable.”

Mr. Parker said that the two airlines have only 12 routes overlapping out of a combined 900 routes that the two airlines serve together. In addition, he said, more cities would be service: American flies to 130 cities that US Airways does not fly, and, likewise, US Airways flies to 62 cities that are not served by American.

“This is an extremely complementary merger,” Mr. Parkersaid.

The combined airline will offer 6,700 daily flights to 336 destinations in 56 countries. It said that it expected to keep all its hubs.

The merger still needs to pass several steps. It must be approved by American’s bankruptcy judge in New York. US Airways shareholders would also have to approve the deal.

In addition, it will be reviewed by the Justice Department’s antitrust division, though analysts expect regulators to clear the deal. The two companies expect the merger be completed in the third quarter.

If approved, the nation’s top four airlines — American, United, Delta and Southwest Airlines — would control nearly 70 percent of the domestic market.

The merger is a victory for Mr. Parker. Over the last year, he persuaded American’s creditors that the carrier needed to expand its network to compete. In April, he won the critical backing of American’s three labor groups, which defied American’s management and publicly endorsed a deal with US Airways.

The biggest challenge for the merged company, to be called American Airlines, will be to integrate operations over the next couple of years. That is no easy task since airline mergers are often rocky — involving complex technological systems, big reservation networks as well as large labor groups with different corporate cultures that all need to be seamlessly combined.

United angered passengers last year after a series of merger-related computer and reservation mistakes, and late and delayed flights.

Mr. Parker has done this before. In 2005, when he was the head of America West, he engineered a merger with the larger US Airways.

In this case, the merged American Airlines will still be based in Fort Worth and have a combined 94,000 employees, 950 planes, 6,500 daily flights, eight major hubs and total revenue of nearly $39 billion. It would be the market leader on the East Coast, the Southwest and South America. But it would remain a smaller player in Europe, where United and Delta are stronger. The merger does little to bolster American’s presence in Asia, where it trails far behind its rivals.

American has major hubs in Dallas, Miami, Chicago, Los Angeles and New York. US Airways has hubs in Phoenix, Philadelphia and Charlotte, N.C., and has a big presence at Ronald Reagan National Airport in Washington.

In reviewing previous mergers, federal regulators have not focused on the overall size of the combined airline but instead looked at whether a merger would decrease competition in individual cities. To do so, regulators examine specific routes, or city-pairs, and look at whether a merger reduces the number of airlines there.

The last time the Justice Department challenged a merger was the proposed combination between United Airlines and US Airways in 2001. It rejected that on the ground that it would reduce consumer choice and possibly lead to higher fares.

Since then, the department has allowed a wave of big mergers that have reshaped the industry, said Alison L. Smith, a former antitrust official and now a partner in the law firm McDermott Will & Emery.

American and US Airways only have about 12 overlapping routes, a figure that is unlikely to set off regulatory opposition, she said. One problem, however, could come up at National Airport, where the combined carriers hold a market share of about 60 percent. There, regulators might request that American give up some takeoff and landing rights before approving the merger.

Regulators sought similar concessions from United at Newark Liberty International Airport after its merger with Continental Airlines.

It is also unclear whether American needs all of its combined hubs. Analysts pointed out that Phoenix was at risk because of its proximity to Dallas, since it makes little sense to have two big hubs so close to each other.

Despite the increased concentration, consumers can still expect to find vibrant competition, said William S. Swelbar, a research engineer at the Massachusetts Institute of Technology’s International Center for Air Transportation.

“We will have four very big, very vigorous competitors in the market,” he said.

Travelers are better served by bigger airlines offering more connecting flights and more destinations, analysts say. Consumers today can easily compare fares and shop for the cheapest flight online, which helps keep airfares in check.

But Kevin Mitchell, chairman of the Business Travel Coalition, disagreed. He said consumers would see few benefits to offset the merger’s negative effects — including “reduced competition, higher fares and fees, and diminished service to small and midsize communities.”

IHT Rendezvous: Mario Draghi Takes the E.C.B.'s Message to Spain

MADRID—The European Central Bank and its president, Mario Draghi, want to ensure that their voices get heard beyond the financial district of Frankfurt.

But their efforts to travel around Europe and spread their message more directly to its citizens have ended up backfiring, at least when it comes to visiting Spain, one of the countries at the center of the Continent’s debt crisis.

Last May, the E.C.B. held one of its regular meetings in Barcelona, under the kind of police surveillance worthy of a city at war and in a convention center on the outskirts of the city, in order to shield Mr. Draghi and his fellow central bankers from anti-austerity street protests. About 7,500 police officers were deployed around Barcelona, with helicopters hovering above, while only a few hundred students gathered in the city center to protest spending cuts by the Spanish government in areas like health and education.

On Tuesday, Mr. Draghi was again in Spain, this time in Madrid to address lawmakers in Congress. The security was less fearsome, but the meeting was held behind closed doors, and Parliament did not provide the usual transcript of such an official session. As a result, regardless of what was said inside, Mr. Draghi’s visit ended up generating more controversy because of its format than its content.

Afterward, Spain’s opposition lawmakers lambasted the president of the Parliament, Jesús Posada, for using frequency-scrambling technology to block any cellphone transmissions within the chamber during Mr. Draghi’s session, to thwart the plans of some parliamentarians who had promised to send Twitter messages and upload videos to keep people informed about what Mr. Draghi was saying.

Valeriano Gómez, the spokesman on the economy for lawmakers from the main opposition group, the Socialist Party, said the restrictions surrounding Mr. Draghi’s appearance had done “no favor to the E.C.B., nor to the prestige of our chamber.” Other leftist lawmakers denounced the format of the event as a violation of parliamentary rules and an insult to democracy.

Mr. Draghi, meanwhile, later spoke to reporters to detail his views on the Spanish economy, while the E.C.B. also published the text of Mr. Draghi’s opening speech to Spanish lawmakers.

Asked about the lack of transparency, Mr. Draghi insisted that that he had not set the rules and would have had no problem speaking more openly before lawmakers if the Spanish Parliament had wanted. Given that videos of his session were eventually released by some frustrated lawmakers, Mr. Draghi concluded that, “I don’t believe anybody missed out on anything.”

Except perhaps Mr. Posada, the Parliament president, who may have hoped to see Mr. Draghi showing a bit more solidarity and helping to justify his communications strategy.

Tech Companies and Immigrant Advocates Press for Broad Changes in Law





SAN FRANCISCO — What do computer programmers and illegal immigrants have to do with each other?




When it comes to the sweeping overhaul of the nation’s immigration laws that Congress is considering this year, the answer is everything.


Silicon Valley executives, who have long pressed the government to provide more visas for foreign-born math and science brains, are joining forces with an array of immigration groups seeking comprehensive changes in the law. And as momentum builds in Washington for a broad revamping, the tech industry has more hope than ever that it will finally achieve its goal: the expanded access to visas that it says is critical to its own continued growth and that of the economy as a whole.


Signs of the industry’s stepped-up engagement on the issue are visible everywhere. Prominent executives met with President Obama last week. Start-up founders who rarely abandon their computers have flown across the country to meet with lawmakers.


This Tuesday, the Technology CEO Council, an advocacy organization representing companies like Dell, Intel and Motorola, had meetings on Capitol Hill. On Wednesday, Steve Case, a founder of AOL, is scheduled to testify at the first Senate hearing this year on immigration legislation, alongside the head of the deportation agents’ union and the leader of a Latino civil rights group.


“The odds of high-skilled passing without comprehensive is close to zero, and the odds of comprehensive passing without high-skilled passing is close to zero,” said Robert D. Atkinson, president of the Information Technology and Innovation Foundation, a nonpartisan research group based in Washington.


The push comes as a clutch of powerful Senate Republicans and Democrats have reached a long-elusive agreement on some basic principles of a “comprehensive” revamping of immigration law. Separately, a bipartisan bill introduced in the Senate in late January focuses directly on the visa issue.


The industry’s argument for more so-called high-skilled visas has already persuaded the president.


“Real reform means fixing the legal immigration system to cut waiting periods, reduce bureaucracy, and attract the highly-skilled entrepreneurs and engineers that will help create jobs and grow our economy,” Mr. Obama said in Tuesday’s State of the Union speech.


In a speech in Las Vegas in January in which he introduced his own blueprint for overhauling immigration law, Mr. Obama embraced the idea that granting more visas was essential to maintaining innovation and job growth. He talked about foreigners studying at American universities, figuring out how to turn their ideas into businesses.


In part, the new alliance between the tech industry and immigration groups was born out of the 2012 elections and the rising influence of Hispanic voters.


“The world has changed since the election,” said Peter J. Muller, director of government relations at Intel, pointing out that the defeat of many Republican candidates had led to a softening of the party’s position on broad changes to immigration law. “There is a focus on comprehensive. We’re thrilled by it.”


“At this point,” he added, “our best hope for immigration reform lies with comprehensive reform.”


Mr. Case, the AOL co-founder, who now runs an investment fund, echoed that sentiment after meeting with the president last Tuesday.


“I look forward to doing whatever I can to help pass comprehensive immigration reform in the months ahead,” he said, “and ensure it includes strong provisions regarding high-skilled immigration, so we are positioned to win the global battle for talent.”


That sort of sentiment delights immigrants’ rights advocates who have banged their heads against the wall for years to rally a majority of Congress around their agenda.


“The stars are aligning here,” said Ali Noorani, executive director of the National Immigration Forum. “You’ve got the politics of immigration reform changing. You’ve got tech leaders leaning in not just for high-skilled but for broader immigration reform.”


Senator Orrin G. Hatch, Republican of Utah, who is co-sponsoring the bill to increase the number of visas available for highly skilled immigrants, said the cooperation went both ways.


“All the talk about the STEM field — science, technology, engineering, mathematics — has awakened even those who aren’t all that interested in the high-tech world,” he said.


While the growing momentum has surprised many in Washington, comprehensive change is still not a sure thing, especially in the Republican-controlled House.


Mr. Hatch said he would push forward with his measure even if the broader efforts foundered. But his Democratic co-sponsor, Amy Klobuchar of Minnesota, said she would press for the bill to be part of the comprehensive package.


Last year, technology executives had a taste of what could happen with stand-alone legislation.


Julia Preston contributed reporting from New York.



This article has been revised to reflect the following correction:

Correction: February 13, 2013

A previous version of this article incorrectly said H-1B visas are capped at 60,000 a year. The basic annual cap for H-1B visas is 65,000.

Well: Getting the Right Dose of Exercise

Phys Ed

Gretchen Reynolds on the science of fitness.

A common concern about exercise is that if you don’t do it almost every day, you won’t achieve much health benefit. But a commendable new study suggests otherwise, showing that a fairly leisurely approach to scheduling workouts may actually be more beneficial than working out almost daily.

For the new study, published this month in Exercise & Science in Sports & Medicine, researchers at the University of Alabama at Birmingham gathered 72 older, sedentary women and randomly assigned them to one of three exercise groups.

One group began lifting weights once a week and performing an endurance-style workout, like jogging or bike riding, on another day.

Another group lifted weights twice a week and jogged or rode an exercise bike twice a week.

The final group, as you may have guessed, completed three weight-lifting and three endurance sessions, or six weekly workouts.

The exercise, which was supervised by researchers, was easy at first and meant to elicit changes in both muscles and endurance. Over the course of four months, the intensity and duration gradually increased, until the women were jogging moderately for 40 minutes and lifting weights for about the same amount of time.

The researchers were hoping to find out which number of weekly workouts would be, Goldilocks-like, just right for increasing the women’s fitness and overall weekly energy expenditure.

Some previous studies had suggested that working out only once or twice a week produced few gains in fitness, while exercising vigorously almost every day sometimes led people to become less physically active, over all, than those formally exercising less. Researchers theorized that the more grueling workout schedule caused the central nervous system to respond as if people were overdoing things, sending out physiological signals that, in an unconscious internal reaction, prompted them to feel tired or lethargic and stop moving so much.

To determine if either of these possibilities held true among their volunteers, the researchers in the current study tracked the women’s blood levels of cytokines, a substance related to stress that is thought to be one of the signals the nervous system uses to determine if someone is overdoing things physically. They also measured the women’s changing aerobic capacities, muscle strength, body fat, moods and, using sophisticated calorimetry techniques, energy expenditure over the course of each week.

By the end of the four-month experiment, all of the women had gained endurance and strength and shed body fat, although weight loss was not the point of the study. The scientists had not asked the women to change their eating habits.

There were, remarkably, almost no differences in fitness gains among the groups. The women working out twice a week had become as powerful and aerobically fit as those who had worked out six times a week. There were no discernible differences in cytokine levels among the groups, either.

However, the women exercising four times per week were now expending far more energy, over all, than the women in either of the other two groups. They were burning about 225 additional calories each day, beyond what they expended while exercising, compared to their calorie burning at the start of the experiment.

The twice-a-week exercisers also were using more energy each day than they had been at first, burning almost 100 calories more daily, in addition to the calories used during workouts.

But the women who had been assigned to exercise six times per week were now expending considerably less daily energy than they had been at the experiment’s start, the equivalent of almost 200 fewer calories each day, even though they were exercising so assiduously.

“We think that the women in the twice-a-week and four-times-a-week groups felt more energized and physically capable” after several months of training than they had at the start of the study, says Gary Hunter, a U.A.B. professor who led the experiment. Based on conversations with the women, he says he thinks they began opting for stairs over escalators and walking for pleasure.

The women working out six times a week, though, reacted very differently. “They complained to us that working out six times a week took too much time,” Dr. Hunter says. They did not report feeling fatigued or physically droopy. Their bodies were not producing excessive levels of cytokines, sending invisible messages to the body to slow down.

Rather, they felt pressed for time and reacted, it seems, by making choices like driving instead of walking and impatiently avoiding the stairs.

Despite the cautionary note, those who insist on working out six times per week need not feel discouraged. As long as you consciously monitor your activity level, the findings suggest, you won’t necessarily and unconsciously wind up moving less over all.

But the more fundamental finding of this study, Dr. Hunter says, is that “less may be more,” a message that most likely resonates with far more of us. The women exercising four times a week “had the greatest overall increase in energy expenditure,” he says. But those working out only twice a week “weren’t far behind.”

Some previous studies had suggested that working out only once or twice a week produced few gains in fitness, while exercising vigorously almost every day sometimes led people to become less physically active, over all, than those formally exercising less. Researchers theorized that the more grueling workout schedule caused the central nervous system to respond as if people were overdoing things, sending out physiological signals that, in an unconscious internal reaction, prompted them to feel tired or lethargic and stop moving so much.

To determine if either of these possibilities held true among their volunteers, the researchers in the current study tracked the women’s blood levels of cytokines, a substance related to stress that is thought to be one of the signals the nervous system uses to determine if someone is overdoing things physically. They also measured the women’s changing aerobic capacities, muscle strength, body fat, moods and, using sophisticated calorimetry techniques, energy expenditure over the course of each week.

By the end of the four-month experiment, all of the women had gained endurance and strength and shed body fat, although weight loss was not the point of the study. The scientists had not asked the women to change their eating habits.

There were, remarkably, almost no differences in fitness gains among the groups. The women working out twice a week had become as powerful and aerobically fit as those who had worked out six times a week. There were no discernible differences in cytokine levels among the groups, either.

However, the women exercising four times per week were now expending far more energy, over all, than the women in either of the other two groups. They were burning about 225 additional calories each day, beyond what they expended while exercising, compared to their calorie burning at the start of the experiment.

The twice-a-week exercisers also were using more energy each day than they had been at first, burning almost 100 calories more daily, in addition to the calories used during workouts.

But the women who had been assigned to exercise six times per week were now expending considerably less daily energy than they had been at the experiment’s start, the equivalent of almost 200 fewer calories each day, even though they were exercising so assiduously.

“We think that the women in the twice-a-week and four-times-a-week groups felt more energized and physically capable” after several months of training than they had at the start of the study, says Gary Hunter, a U.A.B. professor who led the experiment. Based on conversations with the women, he says he thinks they began opting for stairs over escalators and walking for pleasure.

The women working out six times a week, though, reacted very differently. “They complained to us that working out six times a week took too much time,” Dr. Hunter says. They did not report feeling fatigued or physically droopy. Their bodies were not producing excessive levels of cytokines, sending invisible messages to the body to slow down.

Rather, they felt pressed for time and reacted, it seems, by making choices like driving instead of walking and impatiently avoiding the stairs.

Despite the cautionary note, those who insist on working out six times per week need not feel discouraged. As long as you consciously monitor your activity level, the findings suggest, you won’t necessarily and unconsciously wind up moving less over all.

But the more fundamental finding of this study, Dr. Hunter says, is that “less may be more,” a message that most likely resonates with far more of us. The women exercising four times a week “had the greatest overall increase in energy expenditure,” he says. But those working out only twice a week “weren’t far behind.”

DealBook: Switzerland to Require Banks to Hold More Capital to Offset Mortgages

LONDON – Switzerland said on Wednesday that Swiss banks would be required to hold additional capital for residential mortgages amid concerns that the country’s booming property market was overheating.

The country, which already has more stringent capital rules for its banks than other European nations, said lenders would be required to hold an additional 1 percent of risk-weighted assets to make the financial system more stable in light of an “excessive rise in prices in the real estate market and exorbitant mortgage debt.” Banks have until Sept. 30 to comply.

Property values in Switzerland have been rising as investors spooked by the uncertainties of the economic crisis in the euro zone sought a more stable places for their money.

Greater demand for Swiss homes has pushed up prices at a time of low interest rates and led many buyers to take on larger mortgages. The Swiss central bank has been unable to cool the market by increasing borrowing rates because of an overvalued Swiss currency.

An index created by the Swiss bank UBS measuring the likelihood of a Swiss property bubble was “clearly in the risk zone,” the bank wrote in a note to investors this month.

In the final three months of 2012, house prices soared to six times the annual average Swiss household income compared with about four times in 2000, according to the bank. It called the ever-rising demand for properties not intended for personal use “remarkable.”

The government said it was following a recommendation by the Swiss National Bank to increase the capital buffers. “The sustained growth in mortgage debt and rise in real estate prices of residential properties has led to imbalances which pose a significant risk to the stability of the banking sector and to that of the economy,” the government said in a statement.

Mortgage debt has been growing faster than the economy, and mortgage volume in relation to income has reached “risky” levels, the government said, adding that residential property prices had risen more than what was justified by fundamental factors.

UBS and Credit Suisse, Switzerland’s biggest banks, both said this month that they were working on increasing their capital buffers and that the suggested increase would not change their plans.
