I personally would fast lunch first. I found after a month at 65g protein breakfast, I couldn't eat lunch if I wanted to, and I haven't eaten lunch since (two months ago). No hunger at all. I love this method of fasting, lol! I figure eventually I'll stop being hungry for dinner, too, and then I'll know to decrease my breakfast till I'm back at "no lunch but hungry for dinner" homeostasis. Then I think I"ll be ready to fast lunch & dinner occasionally by choice, post-leptin-sensitivity.
