I'm completely wigging out, I just logged my calories for yesterday (I don't have access to a computer in the evenings so I log first thing every morning) and it turns out I ate over 1600 calories! I am doing 5:2 and it was a feed day but I am absolutely flipping out, that is so much!!!!!!!!!! Too much!!!!!!!!!! And I've been ill so no, I didn't exercise yesterday nor will I today. At least today is a fast day, but 1600 calories, I feel like a sloppy fast food gobbling PIG.

According to the above calculations my BMR is 1622.5' date=' my maintenance cals would be 2514, and to lose weight slowly my daily intake should be 1000 less than that - 1514! Huh?? Somebody help me make sense of that![/quote']

BMR is just the amount of calories you would burn in a day if you did nothing but sit on our butt (in other words staying alive)...literally. The maintenance calories, or TDEE is the calories you burn staying alive plus your daily activity including exercise.

But I firmly believe that being on restricted calories for an extended period is going to lower a person's metabolism enough that these numbers will seem inflated.
