A few minutes of light exercise, rather than a sweaty gym workout, is all that is needed to reduce the risk of type 2 diabetes, study suggests

Even small amounts of physical activity can offer health benefits that protect against diabetesEven small amounts of physical activity can offer health benefits that protect against diabetes, new research suggests.

A new study found that even a little exercise wards off insulin resistance, a precursor to type 2 diabetes which can result from a high-fat diet.

Insulin resistance occurs when the cells of the body stop responding to insulin, a hormone that regulates blood sugar levels in the body.

Exercise can prevent insulin resistance by prompting the body to remove damaged cells and enhancing the quality of mitochondria, the cell’s energy powerhouses.

Type 2 diabetes affects 4.5 million people living in the UK and 29 million people in the US.

Even small amounts of physical activity can offer health benefits that protect against diabetes

The study also casts doubt on the previously held view that increasing the quantity of mitochondria could help fix some consequences of a high fat diet, including insulin resistance.

The researchers found that the benefits from physical activity were not affected by the quantity of mitochondria.

Lead researcher Megan Rosa-Caldwell, a doctoral student at the University of Arkansas, found that mice genetically engineered to have higher quantity of mitochondria were not more protected against high-fat diet induced insulin resistance.

How was the research conducted?

The researchers fed all the mice in the study a Western diet high in fat.

The genetically engineered and control mice were further divided into a group that was allowed to exercise, and a sedentary group.

Their results showed that physical activity, regardless of the amount of mitochondria, offered similar health benefits against insulin resistance.

The researchers said that it appears that exercise’s ability to help remove damaged cells and enhance the quality of the mitochondria may be more effective for preventing insulin resistance.

But they said these aspects need to be further tested.

Exercise offers ‘the greatest protection’

Ms Rosa-Caldwell said that with rates of obesity and type 2 diabetes continuing to increase, understanding the cellular processes that help or hurt insulin resistance can help doctors better tailor effective preventative measures such as exercise.

She added: ‘For now, physical activity is the greatest protection, but further research may enable us to prevent and treat insulin resistance, and subsequent diabetes, more effectively.’

The research was published in the journal Experimental Physiology.

You might think that cutting the carbs is the most effective and painful way of losing weight.

After all, No Pizza Before Ibiza must exist for a reason, right?

ew research published in the Journal of the American College of Nutrition claims that the key to shredding might actually lie in a plant-based diet.

Scientists claim that dieters not only lose weight more effectively when following a vegetarian diet but that going meat-free also boosts their metabolism.

Going vegetarian is the most effective 'diet' for losing weight, say researchers

They looked at a group of 74 type 2 diabetes sufferers who were put on a vegetarian diet of grains, vegetables, fruits and nuts.

And the researchers claim to have discovered that that diet was twice as effective as a meaty one.

On average, the newly veggie dieters lost an average of 14lbs versus 7lbs.

As well as simply losing weight, their plant-based diet helped reduce muscle fat which in turn, heightened metabolism.

METRO GRAPHICS

‘This finding is important for people who are trying to lose weight, including those suffering from metabolic syndrome and/or type 2 diabetes,’ says Dr Kahleová.

‘But it is also relevant to anyone who takes their weight management seriously and wants to stay lean and healthy.’

So if you’re trying to slim down or maintain a healthy weight, it might not be a bad idea to try and have at lease one meat-free day a week.

Yet more proof that plant-life rules.

Gmail is dumping Windows XP and Vista, now what?

chromelogo

Life isn’t getting any easier for holdouts on Windows XP and Vista. Google recently announced that Gmail would stop supporting Chrome version 53 and lower by the end of 2017. The move specifically impacts XP and Vista since Google capped support for both of those systems at Chrome v49.

So what does this all mean for XP and Vista users? Is Gmail going to stop working in Chrome? Not exactly, but it could suck a whole lot more.

The first thing that will happen, Google says, is that starting on Wednesday, February 8, a banner will appear at the top of Gmail encouraging users to upgrade their version of Chrome. That’s obviously not going to happen if you can’t upgrade because you’re limited to Chrome 49.

Then, by the end of 2017, it appears that Google could possibly redirect at least some users to the basic HTML version of Gmail instead of the “web app” version you see now, although it’s not a certainty yet.

If the Gmail interface doesn’t change then there’s really nothing to worry about, really. Gmail will continue to work as always, but if Google makes a change that breaks Gmail in Chrome 49 that’s too bad for you.

Where the hard choices come in is if Google does switch XP and Vista users to the HTML version of Gmail. That would mean moving back to the original Gmail interface, which is very basic. You’d also lose a number of useful features including chat, the spell checker, the ability to add or import contacts, rich formatting, customized “from” addresses, and keyboard shortcuts.

That’s a pretty tall list of shortcomings, but if all you’re looking for is the ability to write text, add attachments, and press Send, then the HTML version will meet your needs.

You’ll miss out on chat, but if you’re still using Google Talk a third-party chat client such as Pidgin will cover that.

If the basic HTML version doesn’t cut it for you, the best thing you can do is switch to a desktop program for email such as the built-in Outlook Express on XP. Or you can download Mozilla Thunderbird, which currently supports Windows XP with Service Pack 3 installed.

Thunderbird will give you pretty much everything that the HTML version of Gmail doesn’t. The exception would be customized “from” addresses (also known as aliases), which are dependent on Google. Though if you already have an alias in use, you can use it with Thunderbird.

If you don’t know how to set up an email client, Mozilla has a simple tutorial on how to use Thunderbird with Gmail.

Of course, I’d be remiss if I didn’t also mention that another alternative is to finally upgrade your operating system to Windows 10 or switch to Linux. But who am I kidding? If you haven’t already switched after losing Google Drive, Chrome, and soon Firefox, then Gmail isn’t going to persuade you either.

Weekly poll results: the Galaxy S8 is poised to outsell the Galaxy S8 Plus

The Galaxy S7 edge outsold its smaller sibling, the S7. Now leaked schematics show us that the next gen phones will have even bigger screen, will we see the Galaxy S8 Plus outsell the smaller Galaxy S8?

Our preliminary polling says no – if our math is right, the smaller S8 will put an S7 edge-size screen into an S7-size body. And it won 35% of votes, leading the S8 Plus (6.3” screen in an S7 edge body).

Of course, there are other considerations that might swing the results. The current consensus is that the Galaxy S8 Plus will have a dual camera, while the S8 will not. However, the Galaxy S8 will have stereo speakers while case designs for the Plus model show only one speaker grill.

It’s important to note that the S8 Plus wasn’t second in the polls, it was the hypothetical 5.1” Galaxy S8. Samsung hasn’t made a Galaxy S mini since the S5 generation (the Galaxy A phones took over), but can you imagine how compact a 5.1” S8 will be with these new super slim bezels?

Finally, 16% of voters say they will hold out for the Galaxy Note8 – if bigger is better then it’s clear that the Note8 will be the best, right?

Weekly poll: LG G6 is a clean break from the G5, what do you think?

LG tried something novel with the G5 but recent leaks show it’s changing course for the LG G6. Gone is the removable battery and gone are the bezels (the headphone jack is reportedly safe and sound). The LG G6 is rumored to have an usual 2:1 screen (well, extra wide screens are not that unusual for LG) that will cover more than 90% of the front.

LG officially confirmed that the G6 will be waterproof in addition to slimming down the bezels. Not officially confirmed yet, but reports suggest it will drop the modular design but will keep the dual cameras. Renders show the back will be quite similar to the G5. A Google’s digital assistant will be a highlight of the phone (poised to launch at MWC) but a Snapdragon 835 will not feature due to availability issues (chances are the Snapdragon 821 will be used).

That’s the LG G6 story so far and with MWC fast approaching (starting at the end of February), we wondered what you thought of the narrative so far. Many voiced concerns about the chipset, some were unhappy about the battery (the V20 has a removable battery), though others were delighted at the minimalist bezels. What is your say?

LG G6: a step forward or back?

Love the bezels and waterproofing

Let’s see the price

Sealed batteries suck

Is China’s future-ready plan better?

Had the graded response action plan been in place in 2016, the city would have seen the odd-even scheme just five times over 19 days. Similarly , other “emergency” interventions, including a blanket ban on construction activities, would have scarcely been implemented.In contrast, if Beijing’s system were to be implemented in Delhi, the red alert (most severe) would have covered 78 days in the year. This is because the Chinese city’s system is far more stringent and mainly relies on smog forecasts, instead of actual recorded concentrations. This, according to some experts, helps Beijing prevent, or quickly tide over, very severe pollution episodes.

Greenpeace’s air quality campaigners recently analysed how Beijing and Delhi’s alert systems would play out in 2016 using R Studio -an open source data analytics software. They sourced daily average PM2.5 (fine, respirable pollution particles) and PM10 (coarse pollution particles) data from CPCB for 2016.Delhi would have had 67 “severe” and 110 “very poor” days, as specified in the graded response action plan.

While experts welcomed the graded response action plan, being enforced by the SC mandated Environment Pollution Control Authority in Delhi NCR, a lag of 48 hours in declaring “emergency” could reduce its impact and might allow the worst to pass before it came into force, they said.

Lauri Myllyvirta, senior air pollution campaigner, said: “A delay of 48 hours to initiate the response and, presumably at least 24 hours more before the measures start to have a significant impact, is an issue. As severe smog events take at least 48 hours to build up, the measures should be in effect at least two days before, not two days after the pollution levels peak.” On three out of five occasions, the response would only have been initiated after the worst peak had already passed, added Myllyvirta.

In fact, based on the analysis, he suggested that emergency response could be maintained over the winter months continuously when pollution levels were high. “If measures are relaxed as soon as PM levels fall from emergency to, say , severe, this can render the interventions ineffective.”

Unlike Delhi where the high pollution months are clearly identifiable, in Beijing the levels are variable through the year. Beijing revised its alert system recently based on its experience of previous winters.

Its system is entirely based on forecast or smog predictions now -for example, a red alert is issued as soon as air pollution forecasts show four continuous days of heavy pollution, of which two days may have severe pollution. The same method was followed last December when Beijing had a red alert for seven days. “Most of China’s city-level response plans use forecast or predicted pollution scenarios as criteria. To make a forecast reliable, China’s ministry of environment protection and bureau of meteorology have been advancing the technical mechanism, including an emission inventory ,” said Linsai Dong, climate and energy campaigner in Beijing.

Beijing issued two red alerts each in 2015 and 2016, which according to its environmental bureau’s analysis, reduced 30% of local emissions, added Linsai. “Red alerts in 2016 have been sent in a more organised way -when the ministry of environment protection predicted that the re will be an severe and longlasting smog episodes in December, it sent pre-warnings to the municipalities, including Beijing, notifying the predicted air pollution episodes and encouraging red alerts,” she said.

A CPCB official told TOI, “As of now, the plan is to introduce emergency response only when we have 48-hour emergency levels. People are worried about a November 2016-like smog episode when levels shoot through the roof. But we feel that was a one-off. We are also working on forecasts and have partnered IMD to make predictions robust.”

He also said that the graded response action plan meant to prevent an emergency episode altogether.

Delhi’s action plan for “severe” air days involves closing brick kilns and hot-mix plants, intensifying use of public transport, introducing differential rates during off-peak hours and mechanised cleaning of roads. In “very poor” days, it mandates a ban on the use of diesel generator sets and imposing a hike in parking fee by three to four times.

Is it time to take a break from social media?

Zeenia Baria| TNN | Jan 21, 2017, 01.00 AM IST

Don't let social media take over your life (Thinkstock)Don’t let social media take over your life (Thinkstock)
It’s hard to imagine life without social media, isn’t it? For a large number of the urban population, Facebook, Twitter, Instagrametc. have become de rigueur — such an integral and essential part of life that even the thought of not being able to access them seems incomprehensible. Whether you belong to the category that likes to document every tiny aspect of their life on social media or the one that simply likes to see what other people are up to, there is no escaping its claws. In recent times, several studies have revealed that while social media has its positive side, it can also lead to self-esteem issues, among others. The latest study reported that taking a break from social media just for a week could actually boost mental health.
Social media can be very addictive
Says consultant psychiatrist Dr Pavan Sonar, “Social media can have a negative impact on mental well-being because of its addictive potential. People often get addicted to social media and spend hours of their time there. This can cause reduced productivity as well as relationship issues in real life. As with any addictive substance, social media could also give you a false ‘high’. You may portray yourself better than the real you. The likes and good comments may work as positive reinforcements to do same again and again. Your awkwardness in the real world can be easily hidden in this virtual world. The constant need to get attention might be satisfied here. Your craving for gossip and checking what other people are up to also make you visit the site repeatedly.”
Adds psychiatrist Dr Ashish Gambre, “Social media today is a medium of instant communication where one gets all the news and recent updates from friends and around the world. Unfortunately, today’s youth also look for validation, approval and comparison, which, in turn, can have a negative impact on their mental well-being. There are so many social media sites on the Internet and the reason one gets addicted is simple — you can communicate with a lot of people at one time and share a part of your life with yourcomments, pictures and videos. When one starts getting likes and positive comments, he or she simply gets encouraged to do more.”

How to lower your use

The first thing that one needs to do is understand and accept that there is a problem of spending too much time on social media. Only once this acceptance is made, can one move forward for a positive change.

  • Firstly, track the time spent on these sites.
  • Remove unnecessary apps and notifications from your smartphone.
  • Prioritise your work. First focus on completing your real work; go online only once you’ve finished all your tasks.
  • Go out and meet friends instead of chatting with them in the virtual world.

“By reducing the use of too much social media, one can meet people face to face and make real friends, focus more on the work at hand, increase productivity and thereby, gain confidence. Social media is a great tool to use but it is up to you how you use it for your benefit,” explains Dr Gambre.

Ends Dr Sonar, “People need to acknowledge how social media is causing problems in their real life. Uninstall apps on your smartphone and stick to your decision of spending less time — say maximum 20 minutes — in 24 hours on social media. Curbing your use helps improve mental health more than you realise.

  • It gives you plenty of time to spend on yourself and your near and dear ones in the real world.
  • Helps you to be more realistic about yourself and others.
  • Increases your productivity.
  • Keeps you away from negative emotions that one often encounters online.
  • You remain socially safe rather than isolated.

What the study said

A new study split nearly 2,000 people, aged 34 on average, into two groups. One group would keep on with their social media use as usual. The other group quit using it for a week. Before and after the study period, participants answered questions designed to capture their attitudes about the site and their styles of use. Some were active users, meaning they posted pictures and updates, and some were passive users, meaning that they typically just scrolled through the newsfeed or browsed profiles. They were also asked questions about their life satisfaction and about mental health, including happiness, loneliness, enthusiasm, depression, decisiveness and anger.

After a week, people who’d given up on this were better off in several regards. They had better well-being and life satisfaction. Study author Tromholt Morten said, “The present study provides causal evidence that quitting it leads to higher levels of both cognitive and affective well-being. The participants who took a one-week break reported significantly higher levels of life satisfaction and a significantly improved emotional life.”

Spinal health is essential to combat back pain

Take care of your spine (Thinkstock)Take care of your spine (Thinkstock)
Experts feel that, when it comes to maintaining spinal health, even small changes can help with the healing process over a period of time. Here are some simple ways to support your spine. Keeping these tips in mind will help you prevent back pain issues.

Rest your spine in the correct way
When lying down, make sure that your mattress and pillows allow your spine to rest and be comfortable by giving it proper support. So choose the best mattress that does not harm your spine.

Strengthen your core
Your back and abdominal muscles need to be strong and supple always. Tone them through specific, targeted exercises. Strong core helps to support your spine and take the pressure off your lower back.

Wear the right shoes

Most do not know this, but your shoes are every important when it comes to your spine health. The right shoes support your lower back and keep your spine and body aligned.

Sitting the right way is essential

You must practise good ergonomics while sitting. Limiting the total amount of sitting time is essential. If your job entails sitting down for long, you must take 15 minute breaks every couple of hours. Your spine has to handle pressure if you are sitting for long and slouching or leaning aggravates back pain.

Choose the right chair

Sitting on a chair that encourages a good posture and supports all the natural curves of your back is essential if you want to deal with back pain for good.

Good news! That cuppa coffee is key to your long life

The finding that coffee drinkers tend to live longer than people who abstain has long puzzled scientists. US scientists believe they’ve found the answer – and it’s to do with caffeine. It helps to block chemicals in the blood that promote inflammation, they say. The study was published in Nature Medicine.

Drinking coffee and tea may help people to live longer by reducing chemicals in the blood that can trigger heart disease, researchers have found. Now researchers at Stanford University believe they may have hit on a reason why having a coffee or tea break is so good for us.

Caffeine, the ingredient that gives coffee, tea and some fizzy drinks a lift, blocks chemicals in our blood that promote inflammation. Inflamed blood vessels are more likely to become stiffer – a risk factor for heart disease. Inflammation also plays a key role in many other diseases, the research study said.

Tests on the blood of people fewer of the chemicals linked to inflammation – were found to have more caffeine in their bloodstream. Further investigation revealed that they, as might be expected, drank more coffee than their peers.

A chemical found in chocolate, theobromine, was also found to have an anti-inflammatory effect, although not as pronounced as caffeine.

David Furman of the Stanford University’s Institute for Immunity, Transplantaion and Infection said: ‘More than 90 per cent of all noncommunicable diseases of aging are associated with chronic inflammation.’ Dr Furmann added: ‘It’s also well known that caffeine intake is associated with longevity. Many studies have shown this association. We’ve found a possible reason for why this may be so.’

His colleague Mark Davis added: ‘Our findings show that an underlying inflammatory process, which is associated with aging, is not only driving cardiovascular disease but is, in turn, driven by molecular events that we may be able to target and combat.’

The authors found that in an ongoing study following participants aged 20-30, and another group of people aged 60, those who ‘tended to drink more caffeinated beverages’ had lower levels of inflammatory compounds in their blood.

Further tests in the laboratory in human cell cultures found that caffeine had an active role in combating the chemicals that trigger inflammation. The key chemical combated by caffeine is called Interleukin-1-beta.

When injected into mice, IL-1-Beta led to ‘massive systemic inflammation, along with high blood pressure’. It also led to immune cells – white blood cells that fight infection and – clogging the animals kidneys. It also found more platelets platelets, which make blood more likely to clot.

Dr Davis said: ‘That something many people drink – and actually like to drink – might have a direct benefit came as a surprise to us’.

‘What we’ve shown is a correlation between caffeine consumption and longevity. And we’ve shown more rigorously, in laboratory tests, a very plausible mechanism for why this might be so.’
