I couldn't even find maternity jeans that weren't skinny jeans.
That's like the biggest fuck you ever.
Granted, I have less to choose from in store because I need a petite size, but. Some of this may be generational though. I assume most people who are buying maternity jeans are significantly younger than I was last year, and I'd given away all my normal ones like over a decade prior. It's hard to find non-skinny jeans for my older boys too. My teen girl lives in them, but it seems like everyone else her age does too.
But really, what the fuck is with skinny maternity jeans and horizontal stripe maternity shirts. 
I've been just at the edge of morbidly obese. (though not for quite a few years now, when I worked for a significant weight loss). I will say that while it can be done (if I can do it then almost anyone else can), I honestly don't think that anyone gets to that point without some significant issues OTHER than just food intake going on, as the amount you have to take in to maintain that weight can be a form of self-medication--or they've been significantly injured or ill. I think this is why a lot of folks find it harder to maintain than actually lose, or have a hard time taking the steps to get there. Mine included an eating plan, yes, and more exercise (I'm now an avid runner), but for me to hit the 100 lbs+ loss mark it included counseling and other treatment to address other issues. (Along with a nutritionist). I'm not saying everyone that is morbidly obese has mental issues, but in my experience along with many others I've talked to, there usually is some other stuff going on that needs to be addressed for long term success and maintaining health.
And I wasn't fat my whole life either. What your mind pictures you are and what you actually are can be a total mindfuck a lot of the time, in either direction. Post-baby weight has been a very big stress for me because I still think I look my heaviest until I look at pictures from them and realize that I am so very not. Though when I was at my heaviest, even though I knew that I was, I still "felt" like I did in high school (which was ideal weight, perfect hourglass figure, ect) until I looked in the mirror.
The mind is just very strange sometimes.
I do work towards the body that I feel most comfortable in, but I've got a lot of things going for me than many other folks do: an excellent metabolism and easy athleticism (Until I got help for it I've always been a binger, so to be frank I can probably out eat someone 3 times my size at least in one sitting) which means that I did not put on what someone else doing the same behavior might have. I had the money and time to get professional support when I needed it. I have no significant health problems (no diabetes/hypertension/other diseases). I have a strong support system around me.
I agree that just losing weight is pretty simple, but...I don't know that I would term it easy unless it's just a matter of someone who realizes "hmmm, oh shit, I've been eating like it's swim season even though I quit the team 5 years ago." I think most of the people who are in the 100+ lbs to lose range MAY have a more complex situation, but of course that's not always the case.
