I've exceeded my exercise target – can I eat the extra calories I've burned off?

The short answer is, yes. But it's important to take note of the type of activity you're recording as exercise. If you are logging exercise which is above and beyond your every day routine, such as a gym session, long walk or a jog, then yes, you should be eating back your exercise calories. Not doing so could mean you end up with a very low net intake, which is not helpful to long term weight loss success.

Alternatively, if you tend to log all your daily steps and these are generally just you pottering around, then it may be better not to eat these calories back unless you feel you need to. Exercise calories can be hard to estimate, so it's necessary to be a bit cautious about the type of activity we count as 'exercise' and when it's appropriate to eat back some calories.
