Wearable Technology: are Physical activity and Fitness monitors useful ?

Once we come out of this COVID pandemic, everyone’s attention needs to be focused on the obesity pandemic.

During the COVID pandemic, lot of people started to focus on their physical fitness. People invested in Home Exercise equipment and in wearable technology such as Fitness monitors.

Even before this pandemic, lot of people have started using Fitness monitors.

Are they any good?

A recent study published in British Medical Journal (BMJ) looked the effectiveness of physical activity monitors.

The study authors looked at more than 120 trials involving more than 16 700 participants.

Most of studies they looked at were either European (31%) or North American (40%). Most of these studies included healthy participants (47%), although some included overweight participants (17%).

They found Fitness monitors are generally safe and help to increase physical activity.

Whether the Fitness monitors will help overweight people to lose weight permanently over long term needs further investigation.

Do statins cause muscle aches and pain ?

Yes, Statins can cause muscle aches and pains.

But the number of people getting it is very small and in vast majority of people, the symptoms are not serious.

Most importantly, the benefits of statins outweighs the risk of side effects.

That is the conclusion of a study published in BMJ medical journal.

Health problems in middle age

A recent British study reports that nearly a third of middle-aged adults have at least two Health issues.

This is very a depressing statistic.

Lot of people seem to suffering from high blood pressure, mental ill-health and back problems.

It’s important that people take time to look after themselves even if work and life in general is stressful.

It is also important to note that COVID affects people with underlying health issues much more badly.

On the other hand, middle aged people who have health issues should not despair. They are not an exception and think of themselves as very unlucky.

They can see that lots of other people are also suffering. They should get on with their lives and make it better.

This may sound a bit odd at first glance. But some people do find it reassuring to know that lots of other people are also suffering with same health issues.

For example, Some of prostate cancers patients are relieved when they learn that hundreds of thousands of people are out there, living for many years, after a cancer diagnosis. They are not alone.

Cancer Research U.K. website says this: “An estimated 280,500 men who had been diagnosed with prostate cancer between 1991 and 2010 were alive in the UK at the end of 2010”

Vaccine for the obesity pandemic !

As the world battles the COVID-19 pandemic , there is another pandemic that been going on for decades without any end in sight.

The other pandemic is obesity !

Obesity has caused far more deaths than the COVID-19 pandemic.

The Vaccines promise to end the COVID-19 pandemic.

Wouldn’t it be wonderful if a vaccine can sort the obesity pandemic ? It does not need to be rhetorical question or wishful thinking.

An article in Science magazine reports an association between obesity and a type of body immune cell called macrophages. This raises the possibility of using immunotherapy for obesity.

There is also another tantalising possibility. Behaviours, emotions and eating wrong type of food are often blamed for obesity. What if the entire scientific thinking about obesity is wrong?

In the past, another widespread condition used to be blamed on wrong food and stress. Stomach ulcers used to be very common and very distressing. Modern stressful life, emotions and wrong type of food were universally blamed for stomach ulcers. Then an Australian team proved stomach ulcers were due to an infection. Now stomach ulcers are routinely treated by antibiotics!

Obesity is common among the disadvantaged people in society. All types of infections are common in disadvantaged people. So it is not beyond the realms of plausiblity to hypothesise (suggest) that obesity could be caused by an infectious agent that affects food intake in some way, by possibly affecting sense of taste or smell of smell or feeling of fullness after eating (satiety).

If an infectious agent (e.g bacteria, virus or prion) is indeed found to be responsible for development of obesity, then the vaccines would provide a very easy way to prevent obesity.

Please note: The science magazine article on immunotherapy is based on excellent, high quality scientific work. But the possibility of an infection being responsible for obesity is merely a scientific hypothesis or scientific suggestion. It is based on a personal hunch. It is NOT based on any direct high quality scientific data at this stage !

Obesity kills but is losing weight in old age also risky ?

Losing weight is a New year resolution for many people. There is no doubt that having a normal weight is healthy overall.

But there is always some degree of uncertainty with any health advice and this BMJ paper certainly gives “food for thought”.

Before you read further , you have understand that there are varying degrees of being overweight. BMI ( Body mass index) is the scientific way of looking at body weight issues and it is calculated using height and weight.

Based on BMI, people are usually classified into three groups:

(a) underweight and normal weight (BMI<25)

b) overweight (BMI 25.0-29.9)

(c) obese (BMI ≥30.0)

There is no doubt that obesity is bad for health. The BMJ paper not supringly found obesity in adulthood increased the risk death.

But, intriguingly, just being overweight only without being obese does NOT seem to have MAJOR impact on risk of death in adults.

Paradoxically, the study found that “weight loss from middle to late adulthood was associated with increased risk of death”

It is large well designed study but nevertheless results of observational studies need to be interpreted with caution.

The message from this study is “do not gain excessive weight during early adulthood“. Losing the excessive weight later on might not undo the damage already done to the body.
