Foods to avoid for a flat tummy?

Ok, I like to eat but I do exercise on a daily basis (4 or 5 days throughout the week). I’m usually @ the gym for at least a good 1.5 hr. I do aerobic & anaerobic exercises. I was a little bit overweight for my height but I’ve lost a lot since I started to hit the gym for the past 5 years. Now I’m much smaller & @ a better fit for my height but I’m not thin or skinny. However, I have a problem w/ my tummy. I do crunches & other abdomen workouts but I can’t seem to get that flat tummy. It’s a lil pouch I have as I’m sure many other women have them. I was told to cut out carbs to get a flat tummy but I can’t! As stated, I like to eat but I don’t overeat though. My point is… what are some specific foods to avoid so that I can enjoy eating my carbs but can still get a flat tummy?
