We’ve all been conditioned to read nutritional labels on our food to evaluate how healthy it is. And, with so many 100-calorie snacks available today, it's easy to forget the true issue — your total caloric intake! So, how many calories do you really need in a day?

The answer to that age old question is a bit more complex than you might expect. Your ideal daily calorie intake depends on many factors, including your weight (and your target weight, if you're trying to lose pounds). Also, you have to consider if you have an active or a sedentary lifestyle, whether you’re trying to lose some weight, and of course, whether you are currently or soon plan to be pregnant or breastfeeding.

If you are in decent health, you can get a general idea of your caloric needs by filling these values into an online calorie calculator. Keep in mind, however, if you are in poor health or are under a doctor’s treatment, it is best to talk to your doctor before you establish a daily calorie goal for yourself. Also, if you are setting a goal for weight loss, it might be helpful to talk to your doctor or a nutritionist to help you set realistic, healthy goals.
