This is not down to one thing. Its multi-faceted. This is how I see it (in no particular order)
1. We don't move enough
- I wouldn't categorise it as laziness, but instead it's our way of life and how its evolved
- we get transported as opposed to walking
-we exercise less
-we are addicted to screen time; whether that be social media, gaming, watching movies etc etc. Screen time mainly is something that's done when we're sat still
-moving less means we don't burn as many calories so we have a calorific surplus day after day, week after week, month after month. the body stores these calories in the fat cells and thus we get fatter and fatter
2. Eating habits
-we don't eat as many meals around the table as a family due to different working patterns compared to previous generations
-more working mums means less time for parents to cook a balanced meal
-we eat on the go in this fast-paced society; and such food is often unhealthy
-we buy ready meals and other quick to cook food from the supermarket. this is often laden with hidden fat, salt, and sugar
-we eat vast amounts of takeaway food; much more than in previous generations
-we drink unhealthily; the soft drinks industry is huge and continuously growing; we don't drink just to quench thirst, but we do it for the pleasurable taste which often means additional calories
-the explosion of the coffee chop culture means we are having incredibly high calorific (often creamy) drinks from costa, accompanied by a cake etc
-we eat far too much mayonnaise
3. Marketing
-we are bombarded with advertising for takeaways and chocolate and ice-cream and other such junk
-we have an industry strategy to make bigger seem better; eg foot-long subway, whopper, big-mac, king-size etc etc
-supermarkets still promote junk food with offers eg two tins of quality street for £7!
-unhealthy snacks such as crisps are everywhere we go and usually part of any sandwich meal-deal
4. Normalising obesity
-we are constantly being influenced by media to accept that obesity and fat people are something to be celebrated
-this flies in the face of our approach to other forms of self-harm such as smoking too much, drinking too much or taking drugs
-we now have super-size models that we are told we should adore and marvel at for their beauty and bravery, but this is nonsense. there's nothing to celebrate when seeing someone incredibly overweight, knowing that they're setting themselves up for a future of very severe health consequences. we shouldn't fat-shame but nor should we pretend it's ok when it very much isn't ok. these models are the opposite of a good role-model, and are giving the wrong impression to the impressionable, just as much as the stick-thin models are. both are the extreme, and the extreme is extremely unhealthy
-we aren't doing enough to intervene when kids are becoming fat. we should look at this as potential child-abuse and make interventions for the good of the child and their future health. interventions can be soft such as education for the parents
-too many blokes are proud of their beer-guts and don't see it as a problem; too many women carry on eating for two after child-birth and are subsequently obese for life
Consequences:
Obesity leads to serious health problems. We have a vast amount of the NHS budget spent treating type 2 diabetes which in short, for most, is a completely avoidable lifestyle health problem.
Our nonchalant irresponsible attitude to our own bodies means we are bringing the NHS to its knees completely unnecessarily. Rather than clap the nhs, and campaign for more nhs spending, we would be much better losing weight. That's probably the most effective thing the overweight could do to help the nhs. But being overweight leads to a snowball effect because it leads to musculoskeletal problems which mean they can't exercise and need painkillers, and need diabetes drugs, and then they get high blood pressure and need drugs for that, and have heart problems and breathing problems, get depressed about their weight and want an op to remove fat or have a stomach bypass, and they need a mobility scooter and so on and so on. I generalise of course, but today's beer-swilling, pizza munching game-console addict in his mid-twenties, is tomorrow's diabetes patient. its inevitable but they don't see it coming.
Adults are getting fatter, kids are getting fatter, we are moving less, we are ingesting more calories, we are addicted to mayonnaise, we celebrate obesity and even promote the lifestyle, we shut down any criticism of obesity and class it as fat-shaming.
I don't care what adults decide to do for themselves, but I very much care for innocent kids who are being indoctrinated into this ruinous way of living. The answer isn't a quick fix such as a tummy tuck or a fat-burning pill or anti-depressants. Rather the answer starts at school with education, including practical cookery classes and anti-mayo classes as a part of the compulsory curriculum. Sadly we can no longer rely on adults to raise their kids healthily. Instead it needs to be a bottom up approach where kids educate their parents. The current generation is lost. They have lost the will, the know-how and the desire to eat healthily. We need to get into primary school education and try to turn around this heavily listing oil tanker.
