It is hard...
It is one of the hardest things I have done-
However, it is so worth it!
One thing you didnt indicate is what your start weight was- From my experience- that has a lot to do with initial weight loss...
I have been on the program for 13 weeks, and I love it! Somedays are a huge struggle, somedays I want to throw in the towel...but it is so worth it! I lose on average 2 pounds a week. That's it, no more than that ever! Sometimes its one, sometimes its none-
Keep your focus straight ahead- don't look around to see what others around you are losing, each body is different. Take pride in the strides you are making to improve your quality of life! And best of luck!
