Congrats!
I am maintaining now, but it took me a long time to figure this out. I could lose like no other, but maintaining, pfft, that was hard.
I am happy to say that I am now a maintainer! However, if I do not stay aware, it won't last.
The up side is, I figured out what works for me, and I'm comfortable with what I do.
JohnP is an IF guy, great, works for him. I'm a Weight Watcher person, that works for me. Plus a few other things. I weigh each morning, write it on a calendar above my scale. I track my food and exercise. At the end of the month, I take the calendar and my food journal and look at trends. If it's a bit up, I need to take action, If I'm where I'm comfy, I'm good.
Just for myself, I finally figured out, that this is not about failure, it's about feedback and listening to your body and your mind and learning from it.
