I'm 5'1 121.5 pounds (highest was 132) and I've just hit my 10 pound weight loss mark. Even though I'm short I don't really notice a difference...when did you start noticing the changes in your body? 15lbs? 20lbs?
Also, what is your goal weight? I'm 5'1, 123 pounds (my highest was 132) and I'm trying to get back down to 100-110. I currently eat 1200 cals a day (give or take) and workout 5 times a week. I also don't eat back my calories just because I workout at night and I don't feel hungry after a workout.
