If you are looking to lose or maintain weight and are wanting to find out what your calorie intake should be, I highly suggest seeking out a registered dietitian in your area. They are highly trained in helping you meet your individual health and weight goals.
You can find a registered dietitian in your area by visiting
http://eatright.org And remember, you can lose weight in a lot of unhealthy ways (ie: restricting yourself too much) that can result in long-term negative side effects so its important to work with a professional to lose/maintain weight in a healthy way.
Good luck everyone in reaching your healthy weight goals.
