As many of you know, I'm a numbers-obsessed engineer. I weigh myself daily (in the morning) and use a Google Docs spreadsheet with a formula for filtering out daily fluctuations and reporting a smoothed result. It's got some similarities to the Hacker's Diet or Physics Diet formula, but I like mine better!
I've got daily weigh-in information going all the way back to November, and additional information going all the way back to August 1, just not daily. I've seen my weight go up a couple pounds for a couple days, and I've seen it drop by a couple pounds for a couple days, and I've learned to just roll with it and keep on plugging.
Here's a graph of my weigh-ins and the filtered weight for the past 60 days. Today's day 300 on SP for me, by the way...
The Orange points are the scale weigh-in numbers. Green are filtered values (the values I report on my ticker), and Blue and Red are limits which tell me which days have truly significant deviations from what's expected and what I should ignore.
To give people some reference points, I started Insanity on April 19 (Day 238), and called it off the first time on May 7 (Day 256). My six days of 10K/day (i.e. Stupidity) went from May 9 (Day258) to May 14 (Day 263). I tried to re-start Insanity May 18 (Day 267), and came down with a cold on May 19 (Day 268) which I was then fighting until May 29 (Day 278). My 5K race was on May 30 (Day 279), I re-started Insanity on June 7 (Day 287), and my 10K race was on June 18 (Day 298).
If you look at Days 240-270, you can see why daily weigh-ins aren't for everyone. There are several 1-2 pound daily swings and the hump from days 260-270 is pretty wild. I've actually seen humps like that three or four times in 10 months, so things like that don't phase me anymore. Days 270-290 look like more of the same, but the last 10 days, Days 290-300, look like something new.
In fact, today's only the second day since I started that my spreadsheet would tell me to report a gain. An absolutely minuscule gain, but a gain nonetheless.
Food-wise, the week's been pretty similar to most weeks except for the last two days. My Aunt's memorial service was on Monday (and I forgot to weigh in that morning) but I was already up before that and I didn't eat anything out of the ordinary that day. I ran my first 10K on Friday and I really enjoyed myself and ate quite a bit afterward (food I didn't track and probably never will), and last night we had a BBQ dinner at my sister's house and I ate quite a bit (I did track that...). That might explain the last two days, but again I was already up before that.
Is this the start of a plateau? Is my body finally waking up to the fact that I'm within 5 pounds of having a BMI of 25? It's my second week back to Insanity, so is my body holding onto more water for repair? Who knows? I think the next couple weeks are going to be interesting. I'm not going to change anything as a result of this, but I'm going to be watching carefully. Maybe I'll get some answers, maybe not, but I think it'll be fun to find out!
EVILKLOWN & I have a bit of an informal race going on right now, seeing who will get to BMI=25 (i.e. 169 pounds) first. On Friday, he reported a (small) gain, and conceded the race but I responded right back saying don't be so sure of that - he's still in the running. The 169 pound mark is also significant to my wife; currently she's (still) on a plateau at 108 pounds lost, and has been dreading the day that I pass her for weight loss, which would when I'm at 169 pounds. Sweetie, it might be a bit later than expected...
BTW, just in case anyone's not clear: this is not a "woe is me" blog. If this is the start of a plateau, this is something that I've been expecting to happen for quite a while (I'm actually amazed it didn't happen earlier), and marks the beginning of the next stage of weight loss, one that I fully expected to go through. If it's water retention, it may flush out of my system all at once (I saw a 5-pound loss in 3 days early on - the only thing it could have been is water), or it may stay around for a while. If it's something else, I'll roll with it and keep on going.
