I will answer your question, but realize a couple things first. Unless you are serious about losing weight those crunches will only make your abdominal look bigger, since muscles lie under fat*. Also, keep in mind that targeting certain areas to lose weight in is almost always a mistake. Just try to eat healthy and maintain good exercise. I would recommend just doing aerobic exercise, especially something like swimming because it uses all the muscles in your body especially your core (ie abs).
If you want to lose weight, eat foods that are low in carbohydrates and high in protein and/or water. I recommend you begin eating lots of celery as it has a negative caloric value, meaning eating and digesting it will burn more calories than it contains, is it negligible sure, but it is a fact. Also, foods like boneless, skinless chicken breast will promote muscle gain, as will lean cuts if beef (ie sirloin steak, or tenderloin) cook them under a broiler with limited salting. On salt, keep in mind that salt will make your body retain water, which means more weight. Also know that if you work out hard your body will use the electrolytes produced by sodium, so make sure to at least salt your foods a little. Other foods to consider, carrots, tofu (high in protein), almonds (raw,unsalted), peanuts (unsalted), quinoa, chia seeds, green tea, shirataki noodles, arugula, kale, beef jerky (lightly salted or unsalted), and spinach. Avoid like you mentioned carbohydrates, that means no pasta, rice, bread, crackers, or pastries. Also keep in mind to aim for a 90/10 ratio. That means keep yourself to eating well 90% of the time, but allow one or two small indulgences a day (10%) that way you will be less likely to binge eat.
Don't forget herbs and spices. Things like turmeric, cinnamon, garlic, and ginger are great for metabolism and have well known medicinal properties. Also eating spicy food is great for controlling how fast you eat as well as the digestion of food.
And a really easy "cheat" is drinking only ice water. It forces your body to maintain its core temperature and thusly burns more energy (ie fat). And since its summer and presumably hot where you are at, its great!
*Its true that gaining abdominal muscle will aid in losing weight, but it must be maintained or else it will just get flabby and gross, it is a long term solution. It sounds like you are looking for a simple short term solution, so ask yourself if you will be willing to put in the effort of maintaining the muscle or would you rather just lose the belly fat? Weight lifting will allow you to have a faster metabolism but it is a lot of upkeep.
