Wow - I (male; 45 y.o.) have done virtually the same (2 days/week fast, Tue and Fri, no food intake, only drinks - mostly water, sometimes coffee, rarely some orange juice; on non-fast days ate without restriction) for one year now.
What I find interesting is your mention of a metabolic set point. Wanted to lose a bit more weight (since I still have visceral fat), but couldn't manage to do so. It seems I hit a hard barrier - any caloric deficit during fasting days was magically compensated exactly on non-fasting days; I tried to reduce caloric intake on non-fasting days, but while fasting a whole day isn't that difficult for me, restricting calories while eating seems to only work when my body has met a magical internal quota.
It seems indeed to be a set point. The small uptick beginning of June was when I skipped a fast day once. I'm a bit scared what would happen if I stopped fasting altogether now.
Would be interesting to understand more about the set point - however, some research on the net didn't yield much substantial info. It seems it exists, but how it works exactly and how it can be moved is unclear. And even if trying to move it makes sense. Maybe the set point is ideal health-wise, and is overridden on unhealthy caloric surplus diets...?
The curve looks quite similar: https://imgur.com/a/H4pKkNv
