At the top of this page is a button that says "MyFatsecret" under it is another one that says "Go to MyFatSecret." On the right sidebar is a link to "my diet" click that and then go to e. "setup/change your recommended daily intake (RDI)". Answer the questions and Fatsecret will recommend a RDI.
I will note a few things to you. First, FS's RDI can be a little high. A lot of folks around here will suggest you go between 100 and 300 below what FS recommends for actual weight loss. Second, use the tools on this site. All of them. It sounds silly to log your food but it also allows you to track your exercise. This will help keep you on track and when you are off track and you ask others they can point to the issues a little faster. Third, weight doesn't equal inches necessarily. In the most recently loss of 20 lbs, I haven't lost an inch of fat anywhere...most likely I'm reducing the fat I can't see around my organs, which is fine, but remember weight doesn't always equal inches.
