Lifestyle and gGovernment

Some people think that government is responsible for people’s lifestyles and the plethora of problems related to ithem, like obesity or anorexia and bulimia.

That being said, we should be realistic and notice that some parents do not really care about their children, as I sawhave seen frequently.

I do not believe that if a government decided to eradicate junk food or added sugars in food would, in and of itself, disappear all problemsproblems would disappear related to it; t. That is wishful thinking.

This is not a matter of political parties or ideologies (as sometimes they are ignorant when it comes to understand the reality that surrounds them, as they try to mold the world according to their interests), t. This is more about respect and self-consciousness.

There is no point in having tons of propaganda telling you to do exercise if you do not care about thadoing it.

The only thing you need is to behave aslike an adult, (by hook or by crook?).

No entiendo lo que estás tratando de decir aquí.

In the end, my point is: to be careful of what you do today, as it can have egregious consequences in the future.

Lifestyle and gGovernment

If this is a title, then capitalise 'g'.

Some people think that government is responsible for people’s lifestyles and the plethora of problems related to it, like obesity or, anorexia, and bulimia.

Don't forget the comma before 'and' when making a list.

That being said, we should be realistic and notice that some parents do not really care about their children, as I sawhave seen frequently.

'As I saw' vs 'As I have seen' - It is a finished action, so use - have seen. I saw is used usually when paired with a noun or verb in a sentence, whereas here you cut it off from the noun/verb, using it as a stand-alone clause so you must use 'I have seen'.

As I mentioned before, I hadve been in contact with these issues several times.

It's more of a phrasal verb/collocation to say it this way.

Nonetheless, as a person that tries to halive a good lifestyle when it comes to diet, sometimes it is really difficult to find healthy food in supermarkets.

When you decide to raise a kichild, it is not like having a plant.

Kid is a very informal way of saying child. This word does not follow the same register as the rest of your piece of writing. Better to use - child.

One has to be aware of how difficult, and, sometimes, excruciating this mightcan be.

Unfortunately, these issues are found not only found in diet but also in studies.

I would swap these words, sounds more natural but what you said makes complete sense.

I do not believe that if a government decided to eradicate junk food or added sugars in food, it would, in and of itself, disappear allerase all of the problems related to itan unhealthy lifestyle/obesity/health issues; that is wishful thinking.

The first clause sounds a bit clunky, especially towards the end. Needs to be a separate clause with 'would'.
'It' is too vague, it's been a while since you brought up the problems of obesity, etc. So better to clarify.

Parents have to be careful and conscientious/conscious about their children and not to expect someone else to raise them.

This is not a matter of political parties or ideologies (as sometimes they are ignorant when it comes to understanding the reality that surrounds them, as they try to mold the world according to their interests), this is more about respect and self-consciousawareness.

Better to use 'awareness' here. Because consciousness is already a part of ourselves, we do not need to add 'self' here.

There is no point in having tonsan abundance of propaganda telling you to do exercise if you do not care about thait.

'Tons', is quite an informal register compared to the rest of your text.

And, as it seems crystal clear, I hope nobody expects to find someone at your door, compelling you to follow a good lifestyle.

I am not sure why you added - as it seems crystal clear. Seems lost in this sentence and unnecessary.

The only thing you need is to behave aslike an adult, by hook or by crook.

Wow, even I did not know of 'by hook or by crook', well done!

I emphasized that concrete children’s case as I think my message would be clearer.

Really not sure what you're trying to say here, sorry
