if losing weight is that important to you, you can alter your environment so "today's world" doesn't make it so tempting to eat crappy foods

What part of "None of the simple cute little solutions that seem like they really ought to work and do work for the metabolically privileged actually work for me" do you not understand? I've lived in a carefully crappy-food-free apartment and gained weight, and back when I was "losing weight thanks to willpower and exercise!" I ate Little Debbie's poison nuggets and lost weight.

You are ignorant of the governing laws. I don't know how to make it any clearer. Your mind is full of things that sound like good and virtuous truths of a fair and sensible universe where diligence is rewarded and laziness punished. These things are lies.
