Obesity and mortality: a review of the epidemiolog...[Am J Clin Nutr. 1997] - PubMed Result
There's an example of a study where obesity and increased mortality are linked directly enough to be considered causation. More studies I've just googled speak of a direct link between obesity and certain diseases. Obesity != overweight, for the record.
It's quite intuitive really. More cells are needed to maintain a larger body, each cell has a set chance of becoming cancerous, larger body, more chance of cancer. There are more factors involved, that's just an obvious extrapolation.
Heart disease is another one. Heart size is linked to height and frame, as well as other set genes, it can only increase in size naturally due to fat. The harder the heart has to work, the more chance of heart failure occurring. The larger the body, the harder the heart must work, larger body=more chance of heart failure.
Stress levels are quite obvious too. Cholesterol and insulin levels are both strongly linked as well.
I'm like you, except more extreme probably. I don't think murderers should be blamed for killing people. Honestly. No-one has free will, why blame them for their environment? Why blame the environment for the environment? They should still be stopped, however. The same way obese people should be encouraged and helped to loose weight, if they choose to. How do we start that? By blaming them of course!
I know a few obese people, one who is very obese, he eats barely anything, and when he does it's take aways and the like. He drink lots of alcohol however, and he doesn't exercise. That is why he is obese. Yes, it's his environment that caused it, the same environment that drives people to do all sorts of crazy things they get blamed for. Why is obesity any different?
You can split obese people into two categories. Those who want to be obese or do not care. (In which case, great! Go for it!) And those who don't want to be obese. Those who don't want to be need to take responsibility for their situation. It may be unfair, but so is paying to repair something that only broke because you happened to be the 4567th person to use it, or having to pay extra money to live because you have cystic fibrosis, or having to get insurance again because your house happened to be robbed. You can blame whatever you want for it, but in the end the only person who can do something about it is you.
Okay, we could force people to loose weight, but who wants to do that?
