Study Finds 10,000 Steps a Day Won’t Prevent Weight Gain and It’s Not a Surprise
For many years now, 10,000 steps a day has been touted as a technique to lose weight and prevent weight gain. But says a new Brigham Young University (BYU) study, 10,000 steps—or any other number— will not do the trick. Researchers from BYU's exercise science department, along with colleagues from the nutrition, dietetics & food science department, studied 120 freshmen’s first six months of college, while they participated in a step-counting experiment. The participants walked either 10,000, 12,500 or 15,000 steps a day, six days a week for 24 weeks, while researchers tracked their caloric intake and weight.
 
The researchers wanted to evaluate if progressively exceeding the recommended step count of 10,000 steps per day (in 25% increments) would minimise weight and fat gain. 
 
However, it didn't matter how many steps the students walked. Even if they walked more than 15,000 steps, they still gained weight. During the period under study, the students gained on an average of about 1.5kg. According to previous studies, during the first academic year of college, students gained an average of 1kg-4kg.
 
"Exercise alone is not always the most effective way to lose weight," said lead author Bruce Bailey, professor of exercise science at BYU. "If you track steps, it might have a benefit in increasing physical activity, but our study showed it won't translate into maintaining weight or preventing weight gain." On an average, the students walked approximately 9,600 steps per day prior to the study. 
 
Although the increased walking failed to control weight, there were obviously emotional and other health benefits. For example, one outcome of the study was that sedentary time was drastically reduced in both the 12,500-step and 15,000-step groups. In the 15,000-step group, sedentary time decreased by as much as 77 minutes a day.
 
Why do people believe that 10,000 steps a day will promote weight loss or even prevent weight gain? Because of widespread false belief that exercise helps weight reduction. We will quote a passage from Why We Get Fat and What To Do about It, by Gary Taubes. “As it turns out, very little evidence exists to support the belief that the number of calories we expend has any effect on how fat we are. In August 2007, the American Heart Association (AHA) and the American College of Sports Medicine (ACSM) addressed this evidence in a particularly damning manner when they published joint guidelines on physical activity and health. 
 
“The ten expert authors included many of the pre-eminent proponents of the essential role of exercise in a healthy lifestyle. Put simply, these were people who really want us to exercise and might be tempted to stack the evidence in favor of our doing so. Thirty minutes of moderately vigorous physical activity, they said, five days a week, was necessary to maintain and promote health. 
 
“But when it came to the question of how exercising affects our getting fat or staying lean, these experts could only say: It is reasonable to assume that persons with relatively high daily energy expenditures would be less likely to gain weight over time, compared with those who have low energy expenditures. So far, data to support this hypothesis are not particularly compelling.”

    What is the origin of '10,000 steps a-day'? To find out, we must look to Japan. In 1965, a pedometer was invented by Dr Yoshiro Hatano who worked for a company called Yamesa. He named his new device 'Manpo-kei', which literally translates as, '10,000-step meter'.

    One Egg a Day Causes No Harm, Finds a New Study
    Eggs are a rich source of essential nutrients, from protein to choline; but they are also a source of dietary cholesterol. Numerous studies in the past have published contradictory findings about the benefits of, or harm caused by, regular egg consumption. Now, a new study has found that consuming one egg daily is not tied to higher blood cholesterol levels and cardiovascular disease, even in individuals with a history of such conditions. 
     
    Researchers at the Population Health Research Institute (PHRI) of McMaster University and Hamilton Health Sciences published their findings which counter old-school nutritional guidance. The findings have been published in the journal American Journal of Clinical Nutrition.
     
    For the study, researchers analysed data from three large multinational studies involving over 177,000 healthy and vascular disease participants, covering people from a total of 50 countries and six continents at different income levels. The three studies, which were conducted by PHRI in the past, recorded egg consumption of 146,011 individuals from 21 countries in the ‘Prospective Urban Rural Epidemiology’ (PURE) study and in 31,544 patients with vascular disease from the ‘Ongoing Telmisartan Alone and in Combination with Ramipril Global Endpoint Trial’ (ONTARGET) and the ‘Telmisartan Randomised Assessment Study in ACE Intolerant Subjects With Cardiovascular Disease’ (TRANSCEND) studies. 
     
    Dr Salim Yusuf, principal researcher of the PHRI study and director of PHRI, believes that previous studies on egg consumption and diseases have been contradictory due to their relatively small sample size. “This is because most of these studies were relatively small or moderate in size and did not include individuals from a large number of countries,” he said. 
     
    The results of this study suggest that there is no harm from consuming eggs, given that the majority of individuals in the study consumed moderate amounts of eggs, according to researchers. 
     
    “Moderate egg intake, which is about one egg per day in most people, does not increase the risk of cardiovascular disease or mortality even if people have a history of cardiovascular disease (CVD) or diabetes,” said Dr Mahshid Dehghan, author of the study and PHRI researcher. 
     
    “Also, no association was found between egg intake and blood cholesterol, its components or other risk factors. These results are robust and widely applicable to both healthy individuals and those with vascular disease,” she further added.
     
    The study also reports that effects of egg consumption may vary across populations with varying diet quality, such as a low- or high-carbohydrate diet.

    Alliance of Doctors for Ethical Healthcare, urges Government to make Ethics Code Mandatory for Pharma Cos.
    Speaking out against pharma sponsored freebies for medical practitioners, doctors under the Alliance of Doctors for Ethical Healthcare (ADEH) have demanded that the Uniform Code of Pharmaceutical Marketing Practices (UCPMP) be made mandatory for all pharma companies. This press release comes days after reports that the Prime Minister had warned pharma companies of bribing doctors. 
     
    The UPCMP code, which was prepared by the Department of Pharmaceuticals in 2014 as a code of marketing practices for the Indian Pharmaceutical industry, has remained a voluntary regulation to be adopted by pharma companies. 
     
    “It is unfortunate that even after 5 years the code remains voluntary. This is despite the fact that global experience also shows that voluntary code does not work,” stated the ADEH in its press release. 
     
    According to ADEH, pharma companies, “spend crores of rupees through associations by sponsoring medical conferences. They spend a huge amount on travel, accommodation and other expenditures on the doctors for lavish arrangements of the conferences.”
     
    As per the Indian Medical Council (Professional Conduct, Etiquette and Ethics) Regulation, 2002, doctors are “mandatorily prohibited from taking gifts, travel facilities, hospitality and cash or monetary grants from pharmaceutical and allied health sector industry”. The said regulation further authorises the Medical Council of India (MCI) and respective State Medical Councils to award punishment to a doctor against any act in violation of the code of Ethics for doctors. 
     
    As per clause 7.2 of the UCPMP, “companies or their associations/representative shall not extend any hospitality like hotel accommodation to health care practitioners and their family members under any pretext”. But since the aforementioned codes have to be adopted voluntarily, the ADEH claims that pharma companies are flouting the regulations with impunity.
     
    The release also makes mention of the Medical Council of India (MCI) amending the Indian Medical Council (Professional Condict, Etiquette & Ethics) Regulations, 2002 to exempt the Professional Association of Doctors from the purview of medical ethics. “There is an urgent need to take steps to reserve this amendment of the MCI and make the UCPMP mandatory,” reads the release.
     
    ADEH has also asked the government to take appropriate action to bring corporate hospitals under the purview of medical ethics as they “take advantage and openly flout” medical ethics since they are currently  not covered under it. 
     
    Addressing the issue of tax treatment of expenses by pharma companies on freebies, the ADEH release states that the Central Bureau of Direct Taxes had decided in 2012 that no tax exemption will be given for such expenses since they were forbidden under MCI’s ethics code. However, in July 2018, the Pune bench of the Income Tax Appellate Tribunal reversed this in a separate ruling. Thus far this ruling has not been challenged by the government and ADEH has demanded that they take corrective action by making the expenses on freebies taxable.
