Most people use the scales to track their progress. It is good to know your weight but this method of tracking wont take into consideration any muscle you may have gained and as we know a small amount of muscle weights the same as a large amount of fat! It can be disheartening to step on the scales and not see the numbers go down.
Two methods which are much more effective in seeing a difference are taking progress pictures and taking weekly measurements.
To take progress pictures you need to get your bare stomach out! Scary for most! I need to start doing this myself. I'v been taking my progress pics in my clothes but to really see the difference I'm going to have to grin and bare it. I'll just have to remember that the first photos I take are just the starting point and as the months pass the pictures will only get better ;) Take pictures from the side and from the front. If you have someone to take pictures for you definitely use them. Photos don't lie and you will soon start to see the difference when you see the pics side by side.
The second thing you should do is to take weekly measurements. You will literally see the inches fall away :) Take measurements of your waist, hips, mid-thigh (left + right), top-thigh (left + right), bicep - unflexed (left +right) and calf (left + right). Don't cheat by sucking everything in :P
It takes time before you start seeing results. It may not happen in the first week but when you start to see and feel the difference it will keep your motivation going :)
