How long have you been doing leangains? I'm not in the leangain club, so I not going to pretend I know the ins and outs. I just know you guys are really picky about when to eat, so has you're fasting for somewhat long periods. If you're new to the program this sounds like it might be the case.
All that junk food sounds like it's probably the main cause. Plenty of Primal approved carbs; sweet potatoes, tomatoes, fruit, some dark chocolate, milk, etc.
