It is almost impossible to account for every calorie you consume each day but I like to have a rough idea. I have been using the calorie charts on bhg.com. It is just a good reference and it covers all the main food groups. This past Sunday night I made a simple grilled chicken salad with minced cilantro and mint...yum! Anyways I know grilled chicken is low in calories but I really had no clue how low. I hopped online real quick and found out that 3 ounces of cooked chicken breast with no skin is only 140 calories. It's just good to know
