Which it was. I didn’t expect to hold myself to perfection, but to see what happens when I try to go without any kind of rewarding food: nothing salty, sweet, fried, etc. I ate the same things each day: boiled unsalted potatoes, plain unseasoned seitan (usually microwaved), unflavored plant protein shakes, and plain vegetables. My daily exception was a glass of red wine at night, and I had a planned exception day each week.
It went pretty well for the first few weeks — I had some small cheats for various reasons, and while I struggled from time to time, for the most part I was able to stick to the challenge.
Then we moved to a new home, and that took several days of packing (I did fine during the packing stage) and then a big moving day followed by several days of unpacking, moving furniture around, hanging paintings, fixing little broken things, etc. It was exhausting and my self-control reserves were wiped out and I didn’t plan my food well so that I just ate whatever I could get my hands on.
Then my head was out of the game, and I just couldn’t get back on track, so I gave up a little before the month was over.
Still, I learned a lot, and I’m really happy with some of my improved skills.
