How to recover from a day of poor eating.
DO:
Try not to worry about it.
One day isn't going to make much difference to your progress.
Get back to the plan tomorrow.
Acknowledge what triggered the poor eating and come up with a plan for next time.
DON'T:
Don't beat yourself up about it.
Don't think 'F*ck it' and eat everything in sight until your insides hurt.
Don't starve yourself to compensate.
Don't use cardio as punishment as a way of burning off the extra calories.
