If it were me, I would wait until my weigh-day. Your weight fluctuates throughout the day/ week and you will see those gains and losses. Now if you have a gain on your weigh-day then you need to record it to keep yourself accountable.

I don't know if it would help you, but I find weighing myself every day to be helpful. I can see how my weight fluctuates by as much as 3 lbs. daily, only occasionally having to do with what I ate, a lot to do with how much I slept, and a little to do with that time of the month. I weigh as soon as I wake up, after using the bathroom, before I eat or drink anything. I know a lot of people feel this is excessive, but seeing the number every day keeps me from obsessing and in a way it makes it less important. When I weighed myself every week I found I was thinking about it constantly, and was devastated when my weight was the same from week to week (whereas now I can see that on a whole the line is dropping, it just goes up and down at the same time).

Again, I know that this can really hurt some people, but weighing myself in the middle of the day, on a non-weigh-in day, was something I was doing, and thought I'd chime in with what has helped me so much.

Thanks guys! I have to try to remind myself that weight-loss is not linear, but I've noticed that many don't log their gains, but I'll stick to logging on Saturdays and I'll add the gains if they happen then.

I log my gains if they're substantial (i.e. more than 1 lb more than one day in a row). Thought I'd add that in there

I dont know, I threw my scale out. I just go by how the clothes fit. It's probably water retention.
But it would be good to do so you can figure out how your body fluctuates with TOM and certain foods like sodium.
