I think category 1 is pretty much for body builders who are "cutting"... i.e. getting ready for a competition and trying to get down to unreal body fats levels. But... I could be wrong. I gotta assume I'll never get to that point! I would assume it'd be counter-productive to refeed if you are, but I don't know.
I don't do refeeds, they make me ill. He says on his forum that if they don't agree with you, don't do them. Also, I've really toned down my free meal(s). Its now just slightly more calories and a bit more carbs. Not the face stuffing session I used to do.
I felt like it was setting me back and reinforcing some bad behaviors. But then again, my reform has only been for a week so far.
I haven't tried yohimbe, after I got used to the diet I didn't really feel like I needed appetite suppression.
Yes, NF dairy includes skim milk. However, recently I've gone back to half&half for the coffee. Doesn't seem to have significantly slowed the weight loss and it makes my tongue much happier.
Ok, just so you know, I've tweaked this diet a lot to make it liveable for me. So take my advise with caution.
