Fat people are not "those people over there" to me. I am in that group. Actually no, I am not "fat". I am 15 pounds over the line between overweight and obese; I am a "fucking lardass".
The fact is that many fat people come up with all sorts of justifications and excuses to try to make themselves feel better. If you honestly have not noticed this tendency, take a look at the "fat/body acceptance" social movement. It is a real phenomenon, not imagined.
Right, so all of the conventional wisdom that you're putting out (portion control, willpower, "fucking lardass", etc.) has essentially been shown to be wrong. Homeostasis is a bitch.
Weight control is far more about maintaining healthy insulin and hormone levels - more sleep, less sugar, alcohol and carbs, some moderate exercise but not full-on jogging - than denying yourself food.
If you haven't already, I highly recommend reading "Good Calories, Bad Calories" - it goes into a lot of the scientific background, weight loss and overfeeding studies, etc.
Your body doesn't have permission to violate conservation of mass and energy. If you put yourself in a caloric deficit, you will lose weight, as I have been doing.
Is it easy? Fuck no. Do different bodies react in different ways? Of course. Is there nuance involved in making sure your body reacts optimally for weight loss? Of course Are most overweight people consuming gargantuan proportions of shit? You better fucking believe it.
If you live a sedentary lifestyle and consume many thousands of calories a day, fixing the problem isn't rocket science. Pretty fucking simple, and pretty fucking hard.
The fact that I am a fucking lardass is not conventional wisdom, nor has it essentially shown to be wrong. It is a simple fact. No idea what you were trying to get at there.
"If you put yourself in a caloric deficit, you will lose weight, as I have been doing."
It sounds like you think establishing a caloric deficit is as simple as forcing yourself to eat less and exercise more. Research says it isn't. Some diets result in a lowered desire to eat. Some diets result in an increased metabolism.
> It sounds like you are making an assumption about me that is rather false.
Given your original post about "people trying to justify their poor health" and "big bones", I'd say that assumption is pretty accurate.
