This guy ^ gets it because he's lived it.Though that is part of it, food addiction is very real. Sugar is addictive in that it gives a dopamine rush very similar to that of many street drugs. If someone has been conditioned to consuming a lot of sugar from a young age, it's quite difficult to simply stop. Unlike drugs, you can't just stop eating which is why it's considered the most difficult addiction to get rid of.
It's a compounding lifestyle that I dealt with myself. "I eat because I'm unhappy and unhappy because I eat." You feel down, a full stomach makes you feel good. You indulge. Over indulgence affects sleep making you more tired and down which makes you want to indulge more which makes you even less restful which makes you even more desperate for a dopamine rush and so on. It's much more psychological for many than just being lazy. They're conditioned and addicted to it which means gaining self-control is difficult. Effective long-term weight loss, for many, involves psychiatric care along with nutrition and exercise regiments. That itself is difficult to even get in this country with long waiting lists for treatment that your insurance will not want to cover.
I'm in a very similar boat, and my over-eating issues are compounded by being prone to addiction and near-OCD levels of 'needing' to eat on a schedule regardless of if I'm actually hungry or not. Living in an apartment surrounded by restaurants doesn't help. Working in my company's fancy headquarters that has catered food for breakfast and lunch every day that also has a snack bar, in a 'town center' style area that is also surrounded by restaurants is a problem. It's all heavy food and it's expensive. But I'm down there in the cafe at least three times a day anyway, getting breakfast as soon as I walk in regardless if I already ate something at home, getting lunch at 11:45 to beat the crowd regardless if I'm actually hungry, and getting snacks with movie theater prices mid-afternoon just out of habit. And of course, because it smells good, it tastes good, and the dopamine hits are incredibly addictive. Food is pretty much the only thing in my life that does that for me.
I over-eat because I'm depressed. I'm depressed because I keep getting heavier (and older, among other reasons). Having to figure out a way to severely restrict the one thing I find some kind of pleasure in is ****ed near impossible. Many others are in the same situation.
No one wants to be overweight. No one wants to be unhealthy. No one wants to spend money on heavy, 'bad' food they shouldn't be eating. No one wants to be judged for their unhealthy habits and poor choices. No one wants to deal with the associated health problems. No one wants their relationships affected by it. No one wants to be treated differently because of their size (something I've been experiencing more and more). No one wants to be limited by their size since the world is not built for fat people.
Anyone who says, "How hard is it to just eat a salad and take a walk?" doesn't understand the psychology of obesity. To be dismissed as just being lazy and wanting an easy fix is infuriating. Willpower has nothing to do with it.
