I've been maintaining since July '05. It has been relatively easy for me, but I think that's due to 1) I don't eat grains 2) I refuse to go off plan 3) I am eating the same foods as I did in premaintenance. Lots of fruits and veggies, protein dairy and eggs.
My favorite meal right now? Steak, baked sweet potato loaded with butter, and fresh steamed green beans! YUM-O!!
