Problem is, the article you cited is crap. The vast amount of literature now supporting intermittent fasting easily debunks the idea that you will basically die if you don't eat every x hours.
Also, calipers are horrible? Really? What do you recommend then? Calipers are pretty much the most accurate method of measuring body composition available to people at home. It's not like everyone has the ability to do underwater weighing or has a dexa machine at home. If you are relying on a bodyfat scale then that explains a lot.
Dude, all your problems are in your head. Really.
The problem with those studies is they arnt actually perfomed on bodybuilders looking to maximize muscle mass.... Trying to grow manintain above what you natural levels of muscle mass are is a whole different ball game. I never had the problems I do now with weight/strength fluctuations prior to lifting.... your nutrition requirements become very different...
No serious bodybuilders eat in the way martin beckham (sp?) of leangains etc prescribes, because it ISNT optimal. I notice he also seems to be very endomophic by nature if you look at his before pics he was a very fat kid... and that bodytype seems to be very efficient when it comes to nitrogen retention, thats alot of variance when it comes to how well you can retain muscle and I'm at the oposite end of the spectrum. I tried that way of eating out of curiosity a while back, it was a trainwreck for me, I dont need any studies to say otherwise, my own studys proved it to be a terrible way of eating for my goals.
