I plugged in my info and I would need 2289 calories to maintain my weight, 1832 for weight loss and 1374 if I wanted to lose weight very quickly. I would honestly ignore the extreme fat loss number and shoot for the middle one.

Also don't forget to exercise if you are able. Gaining lean muscle naturally speeds up your metabolism and it has many positive effects for both body and mind. There are many free videos available online that I would be happy to share with you.
