Rant about obese/overweight children

Disclaimer: I realize this is ridiculously hypocritical because of my own issues with food. I do not hate fat people. My own father is quite large. And by that I mean his body fat percentage is probably somewhere around 45%. I'm just fed up with all of the ways we excuse obesity and make it socially acceptable.
I'm sorry, but people should not complain about being overweight. It is NOT a disease. ONLY a VERY SMALL portion of the population ACTUALLY have a thyroid problem, and yet I cannot tell you how many times I have heard a fat person say that they just have a thyroid condition and that's why they can't lose weight. They normally then proceed to eat something roughly in the 700-1,200 calorie range.
People need a reality check: chances are they are not fat because of something beyond their control (even thyroid conditions can be supplemented for with certain treatments). We just like to claim this because it makes us feel better. It's not our fault. It's something we can't control.
In a way it is. The human body is not designed to survive times of plenty. We are evolutionarily conditioned to want to eat as much as possible because in ancient times, these BRIEF periods of feast would often have to sustain us for longer periods of famine or minimal nutrition. In building up our fat stores we were able to survive these times of hardship.
However nowadays, we scarcely have to go a few hours much less weeks on end without a proper meal. Society has made food readily available and full of chemicals and substance our bodies not only do no need, but cannot recognize. They then get stored as fat.
As a society we need to learn how to institute control. We see food and feel compelled to eat it and eat all of it as quickly as possible. Hunger is secondary to food. The worst part of this phenomenon is that we are passing on these traits to the next generation.
I was watching a video today and YouTube and a related video came up of a 4 year old who weighed 114 pounds. Her mother was on a show talking about how hard it i and how she doesn't know what to do. Cut to child eating not one, not two, not three, not FOUR, but five cheeseburgers in one sitting. I think we found our problem.
I got sucked in and watched about 6 or 7 similar videos in a rwo and then I realized: all the parents were fat. And not just chubby, I'm talking HUGE. And they wonder where their child is getting this.
We need to wke the fuck up and realize what we are doing to ourselves. Fat is an epidemic, but it is NOT a disease. People need to stop claiming that it's beyond their control, or resorting to things like Lap-bands, gastric bypass, diet pills, etc. instead of adressing the real reason they're not losing wieght: you have to shange your lifestyle to do so and be sucessful. You can't put on one, two, three hundred pounds, and expect a quick fix is going to make you slim again. you need to change your habits: what you eat, what you do, where you go, how you see food. I just find the entire situation a bit ridiculous, It's like putting a bandaid on a hemopheliac's paper-cut....it'll work for a couple minutes, but then you'll be back where you started, sometimes even worse.
