...a simple definition of lazy is the unwillingness to work for something. Yes, there are other factors, but they can be overcome. It will be tough, no one is saying it is easy. Anyone can find 1000 reasons to not do something. But it really does boil down to one simple question: how important is this to me? If it isn't that important, fine. Give up, quit. Otherwise, saddle up and be willing to be uncomfortable for a while, in the mean time sacrifices for better health need to be made. I refuse to justify unhealthy habits because it's hard. Cowards whine about how hard it is to do something before they give up and if you find yourself in this situation you need to look in the mirror and say "That's not me, I am BETTER than that!"
And, there you go again!
"Lazy...saddle up and be willing to be uncomfortable...cowards..."
It's EASY to beat addiction! It's easy to overcome a stressful social or economic situation! It's easy to challenge and overcome what your genes and microbiota are trying to do to your body! Just BE BETTER by deciding that you are better!
The same way its easy to stop being gay, or stop believing that you are a female person in a male body, or short, or light-skinned...
Your language and position suggest that you have little to no empathy for the situations of others. Maybe you've dealt with addition or race or whatever in your life, and you've managed to "get over it," whatever "it" it was for you. Wonderful. Congratulations.
Others may be fighting not just one "it," they might be fighting several of them--and the number one "it" they are fighting may not be the one you think they should. Your solution is to, it appears to me, shame and suggest that they should change their priorities to YOUR priorities.
Sure, being overweight contributes to lots of health problems, but it is more a symptom of a host of other issues, and it is likely that obesity as a public health issue would go away if we could solve a number of other social problems. Consider: Why is it that hunger, malnutrition, and obesity tend to be highest in the poorest populations in America? Is it coincidence that racial and other social segregation, poverty, lack of decent educational opportunities, lack of jobs, lack of access to effective transportation, and lack of access to fresh and healthy foods also concentrate in the same communities? How about the correlation of crime, substance abuse, and violence with impoverished areas and populations? Where healthcare options are limited? So you think all these things are unrelated to each other? That they don't cause and effect and feedback on each other?
And your solution seems to be for the lazy cowards to just buck it up and be uncomfortable until they are healthy and out of poverty and out of stressful life situations and no longer addicted and so on that are imposed in great measure not from inside people (although people do have to take responsibility for some portion...but that's not always as easy as just hearing a pep talk and deciding to change your eating habits, especially when you have no resources available to help you do so...), but from outside, from the attitudes and actions of other people.
Sorry, but I think your perception of the problem, and the solution, is too simplistic. On an individual basis, weight like any other aspect of our individual being is something we can work to change, if it's important enough. But on a societal basis, obesity is just one symptom of a larger problem that doesn't go away even if we can get everyone to eat a good diet and get enough activity to be healthy. Because, the ongoing grinding stress of poverty and discrimination and the like will still cause people to overeat and gain weight because that's how the body often reacts to stress, and it's often one of the few pleasures that might be available to people in those kinds of situations. Addiction still happens. and so on.
