That's like saying you need to make special accommodations for a crack head, because crapping all over yourself is a "disability".
As a person who has struggled like....a lot with weight loss, what you're saying is insulting on a lot of levels, although I imagine they come from a place of ignorance, not malice.
And I'm not making excuses for a woman who is at worst hypothetical, and at best a brief acquaintance, but like I said earlier, I'm 6'4, 300 lbs, and that's with 2x daily cardio plus a every other day weightlifting regimine. Without my cardio + weights that 300 number gets closer to 350 or 400. At the gym alone, I'm burning 1500 or so calories a day.
What I'm getting at is that your math, while sometimes true, is not always true. I'm not some victim, you should see me play rugby. But my weight is a constant challenge, and for a lot of people I imagine thats true too. Im just saying, don't assume everyone is like you.
