Exercise combats addiction – Study

Yet another reason to exercise regularly! Exercise can alter Dopamine signalling and help with addictive behaviour.

Health Secrets of a SuperAger

As far as I am concerned when it comes to the benefits to our body and brain from exercise, the hits just keep on coming. The University at Buffalo Research Institute on Addictions reports the following good news.

Summary: Researchers report, in animal models of addiction, daily aerobic exercise alters the mesolimbic dopamine pathway in the brain.

New research by the University has identified a key mechanism in how aerobic exercise can help impact the brain in ways that may support treatment — and even prevention strategies — for addiction.

Also known as “cardio,” aerobic exercise is brisk exercise that increases heart rate, breathing and circulation of oxygen through the blood, and is associated with decreasing many negative health issues, including diabetes, heart disease and arthritis. It also is linked to numerous…

My Journey With TFL…

TFL Client TestimonialFor much of my life I was a victim of wanting to lose weight as since my young days had the battle with the bulge. Ten years ago when I moved to a new country and started a new life, I gained a lot of weight. 

I decided to move to India to concentrate on my fitness. I did have lot of thoughts as I had to give up a good job and leave my hubby behind. Most of all I thought people are going to laugh at me and judge me. But, thanks to my family as they were very supportive especially my hubby.

I joined Dr.Sheela Nambiar at TFL Chennai/Ooty, in the year 2009 and since then there has been no looking back at all. I have transformed into a new person physically and mentally.

TFLThe most obvious result of exercise of course is the physical appearance but the benefits of regular exercise to the mind are amazing. 

Since 2009, I have become a mother of two lovely boys. During my first pregnancy, I decided to exercise and continued to train especially as I was diagnosed with gestational diabetes. I was on a  strict diet but it paid off as I had a normal delivery. Second time around I was much fitter and healthier but I still had gestational diabetes.

I was a bit disheartened but I continued to exercise and diet. I had a 4.1kg baby, a big fellow but still managed to deliver him normally, thanks to my fitness. 6 weeks after my delivery I started my exercise routine. I was amazed at my body. Within few days I got back to my regular cardioroutines and weight training and I could see results. I was happy that all effort during my pregnancy was helpful.

6 months down the line, doing regular exercise gives me the energy to handle both my boys and run around with them. No one believes I’m a mum of two!

I can’t thank Dr.Sheela Nambiar for all the input and effort she has put in me.

I’m truly blessed to be under her guidance.

Sitting is the New Smoking

This article was first published in Rotary News in January 2017.

Are you seated as you read this article? How long have you been sitting? Have you taken a break and stepped out? Have you stood up and stretched?

If you haven’t, put this article down, stand up and walk around your room, up and down the stairs or in your garden as briskly as you can for three to five minutes. Then, clasp your hands and stretch them high above your head. Push your clasped hands back as far as possible feeling the stretch in your chest, particularly at the point where your arms meet the chest. Go up on your toes and reach for the ceiling. Take a deep breath and let it out slowly.

There’s something about movement that makes one ‘feel’ better… more invigorated.

Sitting is more dangerous than smoking, kills more people than HIV and is more treacherous than parachuting. We are sitting ourselves to death.
– Dr David Levine — Mayo Clinic — Obesity Prevention Initiative.

This is a relatively new theory but one that has withstood research. Several studies have shown the importance of ‘not sitting’ for prolonged periods of time.

  • Risk of cancers like colon, breast and uterus were found to be increased in a study published in the Journal of the National Cancer Institute.
  • Risk of heart disease increased in those individuals who sat more than six hours a day. They died earlier than their counterparts who sat for less than three hours a day. Something as simple as ‘not sitting for long periods of time’ appears to increase longevity. In another study men who spent six hours or more a day sitting, had an increased death rate, about 20 per cent more than those who sat less than three hours a day.
  • The risk of obesity goes up several times when seated for prolonged periods of time.
  • Risk of diabetes is increased with prolonged sitting in a day — the sensitivity of insulin, the hormone that controls your blood sugar, is decreased with continuous sitting. A study, in the journal Diabetologia, found that out of 80,000 participants, those who sat the most were twice as likely to develop Type 2 diabetes.
  • Sitting interferes with Lipo Protein Lipase (LPL), an enzyme that breaks down our fat. LPL activity is directly related to movement; lying down and sitting still drops levels of LPL to an abysmal low and leads to accumulation of fat.
  • Depression — those who sat for more than 7 hours a day had a 47 per cent higher chance of developing depression.
  • The very act of moving increases the endorphines in the brain and makes one feel better.

The truth is,  however good  your chair, it  is killing you!

The seated position

  • The seated position itself is such that it decreases not only the blood flow to the lower limbs but also the neuromuscular stimulation to the leg muscles, causing them to literally go dead.
  • When continued through life, prolonged sitting causes poor mobility and balance, increasing incidence of falls that we see so often in older people.
  • The position of sitting, especially in our modern chairs, the 90 degree or more flexion at the hip and knee joints, encourages deep vein thrombosis, or clotting of blood in the veins of the lower limbs, as a result of prolonged immobility.
  • —This is irrelevant of great sitting posture. Even if you have your back aligned perfectly, shoulders dropped, core tightened and so on, this still doesn’t help the blood flow to the legs. Good posture may protect your back, but will not circumvent the other negative effects of prolonged sitting.

Your chair

It was only in the 18th century that the ‘chair’ made its appearance. Prior to that we managed with perhaps stools and benches, which frankly don’t encourage sitting for long, as the lack of the backrest will prevent you from even wanting to do so. Nowadays, however, companies vie with each other to make a more comfortable chair than ever before. You have chairs for bad backs, chairs that rotate, slide, swing, massage you, have great quality foam, arm rests, and other features, making it very difficult to get off your back and move once you are seated. The truth is, however good your chair, it is killing you!

In 1992, Dr Levine asked the question: Why do some people not gain weight even when they eat more, and don’t exercise? He then went on to perform an experiment where a group of people were given 1,000 calories a day over their usual diet and were told not to exercise but to continue with their routine work. They were observed for two months.

Some gained weight as expected, while others didn’t. What was the difference? Those who didn’t put on weight, moved more — not exercised, but just moved more. Their bodies inherently understood that they were consuming more than required and to compensate, they just moved more at work and at home. They may have climbed more stairs, stood instead of staying seated, done more housework, and so on.

Just moving increases productivity; improves creativity; ushers in more innovation, improved memory and a better mood.

The very act of moving increases the endorphins in the brain and makes one feel better.

NEAT (Non-Exercise Activity Thermogenesis) is the calories burnt from activities other than structured exercise, which we commonly disregard. NEAT can be increased by fidgeting; moving more; taking the stairs; moving the limbs as much as possible; standing instead of sitting; and doing simple things around the house such as laundry and cleaning.

TV & computer: malaise of the modern world

In a study done in Australia, for every increased hour of television or internet, the risk of dying rose by 11 per cent. Watching a lot of TV causes depression. This, I believe, is partly due to the sitting and perhaps partly the result of the kind of channels you watch!

So, what do you do? Small changes.

  • —Stand up when you watch TV. At least stand 50 per cent of the time, or better still, watch less TV!
  • Watch the news on your treadmill or stationary bike
  • Walk around at every commercial break. There are lots of them. You are missing nothing if you take a walk down the hall during a commercial break
  • Do squats, calf raises or ab crunches during commercial breaks
  • Don’t eat sitting in front of the TV
  • Use a standing desk
  • Move every 30 minutes
  • Slip off the shoes and move your feet and toes
  • Stand up every time someone comes in to see you
  • Stand up every time you answer the phone
  • Stand up and talk
  • Walk the stairs
  • Exercise at your desk

The minimum exercise requirement a day as per WHO recommendation is 150 minutes of accumulated exercise a week. An hour or two of ‘exercise’ does not entitle one to a sedentary lifestyle for the rest of the day. Prolonged physical inertia is not negated with exercise!

Runners are as susceptible to the setbacks of prolonged sitting as much as obese people who don’t exercise. For instance, if you complete your one hour run and then go to your work place and sit for the next eight hours, you are at as much of a risk of developing the problems previously listed as someone who is overweight and not exercising regularly. The hour of exercise does not negate the ill-effects of sitting.

This is why sitting is compared to smoking. Smoking a pack a day and then exercising for an hour will not contradict the detrimental effects of smoking just as an hour of exercise cannot compensate for an otherwise sedentary lifestyle.

How Old Are You Really?

This article was first published in Rotary News in April 2018.

There are two aspects to ageing. Your chronological age is the calculated number of years you have lived. Your biological or “real” age  refers to the current condition of your physiological body at its very basic cellular level. These two are not necessarily one and the same. An individual may be chronologically 30,  but might have the body and mind of a 55-year-old. He could be overweight, lethargic, with poorly conditioned muscles, poor memory, productivity and low stamina. He may be stressed, depressed, with a laundry list of medical conditions and pills to manage them.

On the contrary, someone could be 50 years old chronologically but have an actual age of a 35-year-old in terms of energy, stamina, strength, and pure joi de vivre. 

Factors that ascertain your Real or Biological age

These are blood pressure, heart rate and other metabolic parameters such as  blood sugar and cholesterol, eyesight, lungs, heart, vocal cords, skin turgor, energy levels, physical appearance, condition and tone of your muscles, mental acuity, memory, level of independence, fat percentage, lean body mass and fitness levels (cardio vascular endurance, flexibility, strength, agility, reflexes, balance, coordination and so on).

Your ‘real’ or biological age

Of course genes set the stage for a good or poor quality body. But lifestyle choices are the ultimate predictors of the ageing process. However good your genes, if you subject your body to stressors such as tobacco, alcohol, drugs, poor lifestyle choices on a daily basis like unhealthy food and lack of proper exercise, rapid ageing is imperative. It is said that your genes load the gun but your lifestyle pulls the trigger.

Here are some lifestyle measures that can arrest and even reverse the ageing process:

  • Eat right – Eat food rich in anti-oxidants, minerals, vitamins and fibre. Fruits, vegetables, berries, nuts, seeds and pulses provide protein and good quality fats. Avoid processed and refined food, tobacco and excessive alcohol.
  • Exercise the right way – A well designed fitness routine should include cardio vascular activity such as running, speed walking, cycling or aerobic sessions. It should be balanced with a strength training routine to build muscle and a stretch routine to maintain flexibility of the muscles. Muscles being critical for movement need to be worked against resistance (either an external weight or one’s own body weight) to be maintained at an optimum or improved. They also need to be stretched to maintain elasticity.

Muscle atrophy (decrease) and frailty with age and disuse is the primary cause for lack of mobility. It affects performing even the most rudimentary tasks. Modalities like yoga and total body stretches keep the body limber, prevent pain and addresses poor posture due to muscle imbalance.

Exercise is most definitely the closest we have ever come to an anti-ageing pill. Expensive skin creams that promise wrinkle-free skin, cosmetic surgery, laser ablation, Botox etc. are only solutions to the superficial signs of ageing. They cannot come close to the benefits obtained from a regular heart pumping, well-planned exercise routine.

  • Maintain your body weight – Weight gain with age is not inevitable. With the right nutrition and exercise, it is possible to maintain your body weight and in fact even improve the quality of your body.
  • Manage stress – Stress is very much a part our everyday lives. Eliminating it altogether is of course too much to expect. Managing stress effectively however is possible with meditation, relaxing techniques, time management and training the mind to handle situations and stress differently.
  • Nurture a hobby/passion – Simple things like developing a hobby or even working on something you love and are passionate about can change one’s perspective to ageing.
  • Maintain strong relationships – Strong ties with family or close friends can be enormously rewarding experiences that add meaning to life.
  • Sleep well – Sleep is not only restive but also restorative. Long-term sleep deprivation has been known to be associated with an increase in Type 2 diabetes, obesity, hypertension, depression and even memory and attention problems. Work related sleep dysfunction (such as in shift workers, doctors and nurses), poor sleep hygiene, stress, obesity, overeating near bedtime, can all lead to poor sleep. Good quality sleep is closely related to a good quality, productive life.

To evaluate your Real age, ask the following questions 

  • Do you enjoy life? Do you look forward to the new day?
  • Do you have strong, nurturing relationships?
  • Do you enjoy the work you do?
  • Do you exercise regularly, sleep well and eat healthy?
  • Are you excited to get out of bed in the morning? (Granted that sometimes some of us are too fatigued to register excitement and just wish for a few more moments of blissful sleep, but that is a different discussion altogether!)
  • Do you feel you have purpose and meaning in life or are you drifting along wondering what to do?
  • Are you passionate about some cause or hobby?

Evaluate your fitness 

  • Can you run or even walk up a flight of stairs and not feel like you are dying at the end (or middle) of it?
  • Can you touch the floor standing up without bending your knees?
  • How fast can you walk a mile and how quickly do you recover from the exertion? (Called the One Mile Walk test, this can be evaluated in a gym setting).
  • What is your weight, fat percentage and your waist circumference?
  • How many proper pushups and squats can you do?
  • How much medication, besides basic supplements, sit on your table waiting to be consumed every day?

Ageing is the most natural process of the human body and certainly cannot be arrested altogether. It can however be done gracefully with every attempt made to remain independent and productive, even if only to oneself.
