I used to weigh daily but alot of times I don't now... its hard because I don't always sleep long enough to get back to my low weight I try my best to just weight thursday morning (I am off wensday night so I get 8 hours sleep lol)
I measure the same time as I weight on thursday I was doing it monthly (first thuesday every month) but have since started weight training and desided I wanted to see the inches lost every week since my weight loss was gonna slow lol
