Oh my goodness I use to do this all the time. But then I realize it was slightly crazy lol!
I have made a vow that I will only weight twice a week max, which I may stop all together and just do one.
From recent experience I found weighing myself all the time, I got to know my body, and how it fluctuated from day to day, and through out the day. This was a HUGE negative for me. Because around week 30 I started having slip ups and then I would excessively weigh myself, seeing if it affected me....sometimes it did sometimes it didn't....those times it didn't I felt my will power slip away, and I would cheat a little because my mind set went into 'its not kicking me out of ketosis' mode. It is a slippery slope from going from I WILL NEVER EAT OFF PLAN to oooooh it won't hurt!
So I find multiple weigh ins more harmful for me personally.
Good Luck
