I binge eat terribly. I'll sometimes eat until I feel sick and then look for a 'palate cleanser' that I can eat to stop the nausea so I can eat more.
Some years ago, I got seriously ill and I started eating keto as a sort of response to that. For a while, nearly 2 years, keto worked really well for me. I got fit, I was running a ton, my moods levelled out, brain cleared up. I felt good for the first time in ages and thought I'd really cracked it, found a lifestyle that worked for me that I could sustain. I wasn't overeating and rarely had cravings for food.
But it didn't last, it stopped working for me and I kept binging again, stopped running, stopped eating keto and went through spell of bumping along the bottom, managing a few weeks of keto before binging and messing it all up. Then I gave up altogether. Now I'm the heaviest I've ever been and its getting to the stage where I'm embarrassed for people to see me in this shape. I don't know the way out this.
As for how long without eating, I did a juice fast once that went on for 26 days before I got up one morning and just passed out cold. That was dumb.
I don't know the longest I've been without showering but I'm very comfortable being a stinky, filthy person. Probably a couple of weeks. Something like that. When I'm exercising I shower more often because I get sweaty.
