suggestions for reducing pot belly

nom_less

I am 5'3" and weight 118.75 pounds. I do have a healthy BMI according to fitness measurements. my problem is mainly with the pot belly that i happen to have along with fat in hips n thighs. After reading MFP and other websites online I have understood that one cannot spot reduce. I cardio for atleast 3-4 hours per week. added to that, I walk about 20 minutes everyday. been trying to watch what I eat and log it here at MFP. started working out with a personal trainer for about 5 months now (do cardio and strength training) and have been a regular at kickboxing classes before that( kickboxing for more than a year). now I must be doing something wrong or not doing something,that keeps me from reducing my belly. would like some advice on what needs to be changed.

key to my diary is : food
