Measuring waist in the morning?

Hi BBM team and forum members,

I wanted to ask about if it mattered when I measured my waist? My waist is definitely smaller first thing in the morning (which is when I weigh myself). I know I should be measuring my waist at a consistent time. Should I be using the almost 1" smaller measurement I see in the morning or the larger measurement I observe after lunch/dinner? Trying to keep an eye on it to stay healthy. Thanks in advance!

First thing in the morning is our preferred time.
