MFP is wayyyyy over on calories burned. Some people use it as an excuse to eat back their exercise calories. Don't fall into that trap.
Ignore calories burned. Almost all are wrong. Log your miles and time so you can look back and see if you are maintaining your activity in the future.
6'3" tall, male.
Highest weight was 475. RNY on 08/21/12. Current weight: 198.
M1 -24; M2 -21; M3 -19; M4 -21; M5 -13; M6 -21; M7 -10; M8 -16; M9 -10; M10 -8; M11 -6; M12 -5.
I don't trust the gym machines or any generic calculation that does not involve knowing how much you worked.
The most trusted method is using a HRM.
Depending on where you are in your journey, (especially if you are really trying to lose weight) I would not eat any of the burned calories, I would just consider them bonus. But to really get a good idea of your calorie burn you need to know how hard your heart worked.
I have just ordered a bluetooth HRM and hopefully it will be here soon (not to eat them, just to know how hard I am working in the gym).
