As I have mentioned before, I didn't have a clean week all through January, February and March of this year. I would be ZC from Saturday or Sunday through Thursday and then fail on Friday and/or Saturday. During this time, my weight would fluctuate from 175-ish right after a carb up down to around 171 by Thursday. It did this like clock-work.
My last carb up was March 27, when my wife and I celebrated our anniversary by eating at a Thai restaurant and then having some Easter candy and ice cream later that day. My weight shot up to 179 the next day, followed by 181 the next day!
I returned to ZC after that, except for the Diet Pepsi, and I expected the weight to drop back off like it had been doing. I dropped down to the 176 - 177 range but it hasn't wanted to budge since. Since the difference was in the Diet Pepsi, I felt that the Diet Pepsi was holding my weight up so I stopped drinking it last Friday. It has been six days and the weight is still holding and, in fact, has been slowly increasing over the last three days.
I kind of remembered my weight doing something similar last time, so I went back and reread my journal from last September through the first of November. I had remembered the weight going up right after giving up DP but then dropping off really quickly after that. It wasn't quite that simple, though. It looks like I better expect to stay at the higher weight for a while.
I gave up DP and all AS on September 18. My weight started to creep up after that and peaked after about a week (where I am now). After 10 days, the extra weight dropped off and I was back to where I started. On September 29, I dropped all dairy.
My weight dropped a couple of pounds after that but I held it for almost three weeks. On October 22, I started losing again. This loss turned into an almost six pound loss in a week.
Carbs are bad enough but it looks like carbs plus Diet Pepsi is lethal, weight-wise. I probably really dicked myself this time. All I can do is to stay ZC and wait it out and hopefully remember this next time I want to be stupid.
