DAMN Bob, you're already shredded! That's awesome!
I'm doing the same thing with trying to follow Leangains AND Primal protocols, and it can get really confusing. Obviously, since I'm a female trying to lose weight I have different goals than you .
I hear you on the confusion about calories. Primal diet says "Eat when you're hungry until you're full". Martin is more like "eat giant plates of measured protein in a sitting". I currently count calories, too, and try and get at least 1 g protein per LBM. I have a suspicion I'll have to "up" that sometime soon.
As far as refeeds go, I'll just let you know that from reading about a million other Leangains/Primal forums, some people have decided to add rice back into their diets on LHT days. I'm not sure if that would help or hurt your success. You'll just have to see if you're comfortable with it and track your measurements!
If you haven't already, read this article by Mark on refeeds: http://www.marksdailyapple.com/carb-...d-weight-loss/ This definitely supports the idea that you should be eating WAY MORE than 100 g carbs on the days you choose to refeed.
Overall, I'm a newbie just trying to feel my way around this too. I think, at the end of the day, it's a lot of trial and error. Sorry I can't be more helpful and good luck!
