Tbh Hit my goal early last spring — 71 lbs down from my heaviest, waist went from a 42 to a 34. I'm 42, and maintenance has turned out to be a completely different sport than losing was.
What's worked: basically the same routine, just less of it. I track loosely, get 8-10k steps most days, lift three mornings a week before work. I weigh daily but only pay attention to the 7-day average. If it drifts up 4 lbs over a couple weeks, I tighten up portions for a bit, and it's come back down every time so far.
The mental part was harder than the physical. Losing felt like a project with a finish line. Maintaining is just... Tuesday, forever. Took me a few months to stop needing to feel "done" and start treating it like brushing my teeth.
Also, sleep. Under 6 hours and my appetite is a totally different animal. That one surprised me more than anything.
For the folks who've been holding steady a year or more — do you set a hard threshold before you react, or just ride the wave?
