Figured it was time I had a somewhat quantifiable look at my weight gain. The mirror and things like my waistline are key, but transient bloating, lighting, hair, etc all make it not entirely accurate. As far as I can tell from the mirror I haven’t added much, if any, fat since I stopped trying to lose fat.
I also know I’ve added scale weight pretty consistently since around the end of June. I want to believe it’s lean mass, but I figured apart from the mirror a decent indicator would be the rate of gain, because my understanding is that above a certain rate of gain you’re almost guaranteed to be adding fat on top of lean mass.
I’m going to go ahead and tag @The_Myth @robstein and @BOTSLAYER here as a sounding board. Sorry guys 
I figured I couldn’t simply take my weight on a given day and flip forward a month. Instead, I took an average of my weight over the seven days around the end of June and every month thereafter: 27 June to 3 July, etc. I figure an average over seven days would be reasonably indicative.
End of June 185.4 lbs
End of July 189.3 lbs
End of August 191.1 lbs
End of September 192.4 lbs
Mid October (took an average of the last four days) 194.7 lbs
So that gives
End of June to end of July up 3.9 lbs
End of July to end of August up 1.8 lbs
End of August to end of September up 1.3 lbs
End of September to mid October up 2.3 lbs
Which then gives over three and a half months or 15 weeks an estimated gain of
2.7 lbs per month
0.6 lbs per week
If I do combine that with the mirror, I think that indicates I’m not gaining weight so fast that much of it should be fat. I’ll keep aiming for one extra carb day per week, although admittedly the last two weeks I’ve done that twice. Need to watch that.
I’ve been at 2700 cal/day for the last two weeks, and I’ll stay there for another four weeks minimum - I spent around 12 weeks at 2600 cal/day before going up, and similar for 2400 and 2500 cal/day - and then go to 2800 cal/day, with any addition being carbs.
The aim is to keep adding lean mass (duh), I’m guessing around the same 2.5 lbs or so per month with the mirror being the main indicator. I also think I’ll take some measurements (waist, chest, thighs, arms should do it, right?) monthly as well.
