For me, maintenance has been very similar to losing. But then, everything has evolved. I still keep a meticulous food log. Still keep track of my time-restricted eating and IF. And still discover new things such as what to avoid (for indigestion). I still practice induction most of the time, but my menu ingredients are not limited by DANDR or any other guideline or book, but what works for me. It's rare that I'll add a food or ingredient nowadays, but it happens, and I keep an eye on things / the effect of the addition.
