Snack and dinner and working out

I ate yogurt for a snack. 180 calories.
Dinner was garlic bread 320 calories.
Desert, an Oreo 70 calories.
Working out: ab workout (ab ripper-x)
And running/jogging for 30 minutes.
I'm doing alright (:
So far 1,173 calories.
I also found a picture of myself,
From two years ago when I was at my skinniest. For motivation.
My goal is to lost 20 or more pounds.
However i'd prefer to lose inches more than pounds.
So.
I may start taking measurements instead of weighing myself.
Well we will see huh?
