Were there weeks that you didn't lose weight?

Ive had a few weeks like that, and would get so frustrated! However, my body would adjust itself and the next week the weight loss would be slightly greater.
That said, dont focus solely on the scale. Look at how your clothes fit, your energy level, and your mood/overall attitude towards life. There are so many other measures of success other than what the scale might say!

Yep. After a while, you will know your body and know what is happening and why. I use to get frustrated to no end, but then I started to do some research and I figured out what was happening. I tend to bloat around when I am fertile and when I am going to get my monthly. I know when it is going to happen, so I don't pay any mind if the scale stalls or goes up.

Yeah, I've had that happen a few times. For me it seems like it happens when I add something new like weight lifting and forget to increase my calories. Once I increase my calories to compensate for the extra I'm burning then I usually start to lose again since my body isn't freaking out and going into starvation mode from a lack of calories.

As others have said though, don't worry, just keep at it. Look at what you want to accomplish and what you've accomplished thus far to keep you motivated. : )
