Feeling down today because I gained two pounds. I know weight fluctuates. I'm hoping when I wake up tomorrow I see the scale moving in the right direction.
Try to always weigh yourself first thing in the morning after peeing and before eating or drinking. That will give you the most consistent results because your weight fluctuates throughout the day.
And I think your instinct to focus on weekly numbers is the right one, because so many factors can affect your weight slightly from day to day.
