I've only been in maitence mode once in my life and that was throughout high school! After that I was always trying to lose weight (although some of those attempts were pretty lazy
) or gaining (i.e. just ignoring my weight entirely).
Right before high school I lost some weight and I maintained it by do two things: 1. I was extremely active and would run up to 10 miles/day at times and 2. I ate like my skinny friends. We went out to eat often and I would watch exactly how much food they put into their mouths and then do the same.
I was young then so it never occured to me to weigh myself often, take measurements, restrict my food choices etc. I wish I had been more conscious about such things then, sigh...
Anyways, one thing I plan on doing for the rest of my life is daily weighing. When I weigh often I lose weight/maintain my weight, when I don't I gain. I figure it's the simplest thing I can do to make myself conscious of my weight and what I'm putting into my mouth. We'll see how that works when I get there. I won't be in maitence mode for awhile, though, because we're hoping to TTC once I reach a healthy BMI so this is more for something down the road.
