and losing 7 pounds is better than not losing anything.
Like Dan said, shake things up and add variety, it works. Mix up your proteins, mix up your starches, change your dairies around. Try the variety of different fruits and veggies. It's all about shocking your body. To me, being able to cut back on the caffiene and the daily half pound of gummy bears was a bigger victory than any scale number could be.
Also, you can be losing and not seeing a change on the scale. My large and exciting weight loss total after making six months on maitenance 9 pounds!
However, the last time I was at this weight I was in high school and wearing a size 14-16 and a 1X top. This morning I put on my size 8's and they were loose. The biggest changes are not what you see on the scale.
