If you gain weight after a vacation or holiday, update tracker w/accurate weight! It's tempting to leave lower weight there. But don't b/c I've learned I lose the weight quicker when I can start using the tracker to show a weight loss, vs leaving it at the lower (inaccurate) weight & being reminded daily that you're not there. That negative reminder might hinder motivation where being accurate (& showing drops right away) will boost motivation!
I have noticed this twice myself and both times after vacation weight gains, delayed updating my tracker to show the weight gain. I had a hard time getting the weight off & finally gave in & updated tracker. Then I was able to update tracker w/"losses" immediately & it boosted my spirits/motivation.
