So I've been trying out Stephan's "Food Reward" approach, and have had great initial success with weight loss and hunger control. My only problem so far has been a general feeling of anhedonia. I'm not depressed exactly, but I'm having trouble caring or getting excited about things. My creativity has also plunged (I work in a creative field). I've tried throwing myself into various projects and activities as an alternative way to fire those reward pathways, but the result is just... meh.
Curiously, I went back through some old journals I kept when I did the low fat thing back in the mid-90s, and discovered that I suffered from anhedonia with that approach too (although it wasn't specifically focused on reducing food reward).
Anyone else having trouble with anhedonia?
(I should also clarify that I've been LC/VLC paleo for three years now, so this isn't just some sort of general adjustment to the paleo diet.)
