I've been pondering this question for a while now. After four weeks of maintaining I am finding that a quick 'daily weigh', same time, same clothes, is helping me to keep tabs on my weight.
I am still getting weekly weigh-ins and after doing the daily weight check I add a couple of lbs (for clothes) to see whether I am over the last weigh-in result. If I am over, I am a bit more careful foodwise that day. If under, I can eat a bit extra.
I also factor in up and coming social events and adjust accordingly. Seems to work so far.
I am interested in other maintainers' experiences though. It seems a bit over the top to weigh on a daily basis, but how else can I keep tabs of how I'm doing?
