If you’re tracking calories or points, it’s critical that you don’t get in the habit of eating something today and entering it into the calories/points for tomorrow. Doing so majorly exercises your giving-in muscle and making staying on track on any given day so much harder because you’ll constantly be tempted to do something today and worry about the consequences tomorrow. Losing/maintaining weight all comes down to making each decision a good one and facing the consequences AS they happen, not putting it off.
