Many people find weighing in daily provides a sense of accountability and is helpful for having a good idea of where they are with their progress. For many, it helps to keep progress on track. If you’re able to look at the overall trend and not stress about the fluctuations, then by all means, weigh yourself daily.
Does a 0.4-pound weight gain sour your mood? Or, are you absolutely elated to see that you’re down 1 pound? If doing it daily powerfully affects your mood and behavior, then you might want to reconsider frequency. The number on the scale should not have the power to dictate your mood, the events of the day or your overall quality of life — it’s just a number.
