This is exactly what happened to me as well. I did keto for ~8 months, lost a bunch of weight, and learned that 99% of what's in an american grocery store has a ton of added sugar. Even milk!
My problem is simply controlling the portion sizes of my delicious food - it's SO easy to eat large portions, and it takes weeks of ignoring your stomach's rumbling to get yourself used to reduced portions.
It's not for everyone though; I've just been doing it for a while.
I did 16/8, lunch and dinner so I could eat with the rest of the family. Worked quite well, lost a ton of weight without feeling like I had to do anything. The first couple of days I was starving by the end of the 16 hour break, but I got over it much faster than the constant feeling I need to eat something I get with portion control.
As you said, doesn't work well for everyone though. I'd guess that it maybe works for me cause of the ADHD, as I may still get to have those endorphin hits when eating something I like. I should probably try going back to it, now that we're talking about it...

I use cronometer to track nutrients (macro & micro). It uses data source directly from NCCDB from the University of Minnesota.
