Confusion over maintenance calories

btretiak

So I'm way confused over what my baseline caloric intake should be. MFP calculates my baseline at 2080 with 'light activity.' The calorie calculator at cancer.org calculates my baseline at 2522! That's kind of a HUGE difference! I've also seen a lot of people posting that MFP overcalculates calories burned during exercise so at the end of the day I'm not sure how accurate my tracking is. I've lost weight but have hit a wall....any advice/adds would be most welcome!

THANKS!
