Polar FT60 and calories

tdfarmer

Ihave a couple of questions. I just recieved a polar FT60 today. It is saying I need to burn 5500 calories a week, is that based on a 2000 calorie diet? MFP has me at 1200, I raised it to 1300 so I can net 1300. I weigh 159lb, 38 year old male, 5'8". My goal is 145. been stuck for about 3 weeks thats when I chnged my goal to 1300. Had a mfp friend tell me, she thought I needed to eat more. My hrm was more than double the exercise I had been logging, scared to eat that much more. What should i do?
