Eat back exercise calories?

Depends on what you have your activity level set to. If you have it set to "sedentary", add those calories from working out back in.

What does your eating goal say?

You accepted the perhaps MFP recommended 1400 calories when you do no exercise, perhaps without understanding where that number came from.

So why not accept the higher recommendation when you burn more with exercise, even if you still don't understand how it works?

Meet your eating goals, adjust after a month based on results.

Don't think you understand how MFP works - exercise isn't part of your activity level setting.

So even if you have a "highly active" activity setting for your lifestyle/job (at the other end of the spectrum from sedentary) that still isn't allowing for additional exercise burns.

OP - to back up Heybales, you have selected a calorie counting tool so suggest you try using it as the tool was designed. If your results don't work out as expected then adjust your calorie allowance accordingly. Actual results are a far, far better guide than any estimate.
