Hi. I check my weight weekly but I concentrate more on my measurements and BF%. I take my BF% every 3 weeks just because I am trying to reduce to a low percentage so it's a bit of overkill. I do body measurements monthly. Your clothes are great way to know if you are having success or not. If they are getting loose then that's awesome. The scale might not reflex the inches lost so I wouldn't worry about the scale as much if I were you.
