For what it's worth, i've been taking a monthly photo in the same gray t-shirt since last May. No dramatic side-by-side, just 63 pounds down and a face that looks less puffy.
What surprised me is that my knee pain quieted around month four, before the scale moved much. I track hunger, sleep, and mood in a notes app; the visual change is the last thing I notice.
I'm trying to let the boring middle be enough. If you take progress photos, do you keep them private or show anyone?
