i like to try and put a positive spin on plateaus in that at least the scale isn't going UP. sometimes i might lose a pound a week for 2 weeks and nothing the following 2 weeks. it still breaks down to approximately .5lb/wk loss which is fine by me. i've lost 50 pounds in the last 13 months and i only have 15 to go to reach my goal. even if it takes another 13 months to lose those 15 pounds, i won't mind.
for me, it started out about the pounds but now i realize it isn't even about that. it's about striving to be a healthier person in both mind and body. i've learned so much about myself during this time, the weight loss is just a nice side effect. if you get your mind in the right place, your body will follow.
