Claimer: I was a fatass.
I no longer show any particular respect or pity towards fat people. I've been fat most of my life, but no more.
It all started when a friend, well into the 400lb ~ 180kg, started losing weight like magic. Constant, steady weight loss. He was a fat guy in a family of fat people, the typical case of genetic blamery. I asked how he did it, he said he just counted calories and never broke the limit.
I did the same. I changed my food habits. It was hard in the sense that I've been "trained" otherwise; it's evident to me now that my mother transmitted me her fears of famine in the war. I always had to finish the plate, eat all I was given, and eat a bit more on my own whenever possible.
And the conclusion the very first day I started the control is that I just ate too much. Checked the calories, yeah, it's well added up. WTF, it's lunch and I'm already more than done! After a while I noticed things started expiring and get moldy since with my new diet couldn't keep up with my grocery list habits.
I lost weight mathematically. Kept doing exercise and bumped proteins not to lose muscle, and the average caloric deficit approached frighteningly my weight loss rate following the famous 9kcal/g of fat. Ate 20000kcal less this month? Weigh in and poof, 2.2kg gone.
From then I started analyzing other people's habits. And fat people just eat too much, very, very, very few of them are exceptions.
At this point I just don't understand why I should feel pity and display consideration to fat people while smokers (or meth addicts, or gamblers, or other sorts of compulsive behavior) are almost the worst thing in the world after the Third Reich. Saving some distances, it's the same league.
It's just an unhealthy habit, and the only difference is that it can be seen from outside. It's not a lost limb from an accident, something random that could happen to anyone and deserves pity instead of mockery. 99% of fat people just eat too much, they're just choosing to be, play the victim card too often and lack of education in regards to nutrition just perpetuates this. It's essentially the same as white trash, you can blame the environment but in the end it's you making the choice, but I have yet to see as many people defending juggalos as people defending fat people.
