Well, I'm failing at maintenance so far, but that's what I get for hitting goal on Dec. 17. Instead of panicking and beating myself up about it, I'm trying to relax, do a week or two of 4:3 to get back to where I want to be, then put my maintenance plan into action.
Also, it's a good time to reassess where I am, besides a number on a scale. My big concern right now is body fat %. Even though my w:h ratio is good, I'd like to get that number down. I have a lot of loose skin after losing so much and not having youthful, bounce-back-into-place skin. Plus, strength training is recommended for runners, so there's three good reasons to start a weight program at the gym. I have a friend, a PhD student here, who is qualified as a personal trainer who is going to help me, since I've literally no idea what I'm doing (the internet has SO much information, it's left me exhausted and confused). I'm insisting on paying her.
Another goal that I had when I started IF last March was to reduce processed food, and to generally eat healthier. Between March and about August, this was going very well. First mostly because I was overbuying for fast days, so eating a lot of that really good food (mostly fresh produce) on non-fast days. Then it became a bit of a habit. Then I made a trip to Switzerland and the UK, and ate way too much not-so-healthy food. At least it wasn't processed junk, but it was too much rich food every day. I haven't really gotten completely back to my healthy ways since then. I'd really like to get a handle on that because I think it will be the key to maintenance.
The main processed food I have left in my life is Coke Zero/Diet Coke. I had cut it down to one a day, which was a miracle for me, but since August, I've been slipping. So I want to work on getting it back to one a day or quitting altogether. I don't think I'm drinking as much plain water as when I started IF, so whenever I think of getting a coke, I get plain water instead.
Anyway… sorry for the long, boring update. I felt I needed to write some of that down.
