The other posts are right. You need to make sure you eat so your body does not go into starvation mode. Breaksfast is very important.
Read the packages for serving size information and measure/weigh the food you eat. For example, on serving size of cereal is usually 3/4 to 1 cup. However, if you just pour it into the bowl you most likely are going to eat more than the serving size, thus more calories. This is the same for other foods.
Also, it is a great idea to cut back on the soda. It is just alot of empty calories. Replace it with water but don't deprive yourself totally if you crave it. Start by cutting back and take it from there.
Best of luck!
