We each must find what works for ourselves, that's for sure.
And once a month just would not work for me. I've finally learned that the scale is not the enemy. The whole time it WAS/IS me that was my own worst enemy. The scale is just a method we use to weigh ourselves. To see how much of us there is. WE dictate what we weigh. We can't control it down to the last ounce, but for the most part we DO control what it says. Now that being said, that little piece of equipment WILL fluctuate from time to time, well actually again, it's our BODIES that will fluctuate from time to time. It's next to impossible for it to stay the same on any two given days. There's lots of stuff that that scale needs to weigh - hair, muscle, organs, blood, water, bones and yes - FAT. And that changes on a daily basis.
So yes, I've learned to not let those fluctuations get to me. I've learned to use that scale as a guide and a reminder to keep with the program. To stay on track. It's one of the many tools I use to stay healthy. It's not always the best tool, but it's the only one we've got that will measure me quickly and let me know what's going on with my body. If I've eaten well and it goes up, so be it. Chances are it'll come back down with in a day or so. If I've eaten poorly and it goes up - no shock there. If I've eaten poorly and it doesn't go up, well then I got lucky and chances are if I continue in that vein, it WILL go up. Because I control the what the scale says, for the most part.
Liliann, if you want to peek - well then why not peek? If it's a "good" number, isn't that motivating and rewarding? Won't it help you to stay with your program even stronger? If it's not such a "good" number, well then isn't that a kind of nudge to perhaps shake things up a bit? To stay stronger on plan? A reality check of sorts? Maybe, just maybe one month is a bit long? But then again, maybe not. You of course are the only who knows what's what's best for YOU. Whatever it is you decide upon, and of course that can always be changed, I wish you TONS and TONS of good luck.
