In short you may need to start:

1) Eating healthier, this means:

Eat smaller meals
Eat more meals a day
Don’t starve yourself
Eat more vegetables and fruit
Drink more water
Less sugars and empty calories (less soft drinks, cakes, cookies)
Switch to whole wheat versions of your bread and pasta, brown rice instead of white rice

2) Exercising:

Forget crunches, crunches work your ab muscles but they dont burn enough calories to lose belly fat, if you do hundreds of crunches daily you will have great abs but you wont see them under your belly fat.
Prefer full body exercises they burn the most calories and increase you metabolism for a few hours after your workout.
Get a training partner or a fitness trainer, a very worthwhile investment – of the money you save on junk food for example =)

Try also to reduce stress and get enough sleep. Both of these are related to weight gain and emotional eating.
