Narrative:

During taxi out at ewr to runway 22R final weights were up linked and loaded by first officer. The zero fuel weight was entered instead of gross take off weight (gtow) by mistake. Winds were gusty; so I requested that we not use reduced thrust. I did notice speeds seemed a little slow but assumed it was for full thrust take off. With distractions from before takeoff checklist and ATC I failed to confirm proper gtow was entered on takeoff data. I flew normal takeoff. Rotated when v1 rotate was called. Rotated to 6.3 deg and let airplane fly off runway. Time from rotation to lift off was a little longer than normal. That was the only clue that takeoff speeds were not correct. Plenty of runway left at liftoff and safety of flight was never jeopardized.

Title: B737 Captain reported the zero fuel weight was entered into the FMS instead of the actual gross takeoff weight during preflight which caused the aircraft to be heavier than what the takeoff performance data reflected.
