what I am confused by is the "low calorie days", so is this a low cal / low carb diet too?
I would think that a low calorie day on CKD is something like 2000 calories?
Also, how long does a UD2 cycle last?
I know, I know, I am getting the books, but I am so curious it's killing me!
Yes. And you really have to read the book to get a full understanding. There are more chapters explaining the physiology behind all this than there are chapters explaining the program, so you'll learn a ton.
It all depends on the individual. From what I remember, on the low carb days you're cutting calories by 50% from maintenance.

And you're doing ridiculously high volume training (pumping and toning isolation crap too) that makes you want to vomit.
Fun stuff.
I forget if Lyle throws out a recommended time period to use this approach. I can't why you couldn't use it for an extended period of time though. I used it for months.
I think you'll be surprised by the comlexity of this diet. It's not something to jump into until you fully understand it. You're a smart guy and will without a doubt be fine... just be prepared for the complexity.
HOLY FUCK STICKS!... 50% of maintenance with training added in or without? Because with training, that is about 1500-1600 calories for me... and without training it's somewhere close to 1200!!!![]()
Interesting... because when I do HIIT, it kicks my ass, but doesn't make me want to throw up either (like most people says it does), and at first I thought I was getting it wrong, but apparently my heart rate gets into the low 180's when I get into a 1 minute sprint at about 13-14 mph. So I am def doing it right... I think I have a high tolerance for shit like that.
Good, I am thinking it's a good cut until July or so... from April to July. Then start eating maintenance from July to September, then begin a new bulk? Dunno, I have a two year plan of being 190-195 @ 11% or less.
With exercise I presume since, again if memory serves me right, Lyle uses the very basic forumula I use around here of maintenance being 14-16 calories per pound. Those numbers include exercise.
He explains to the reader that you can use the above formula if you don't already know your maintenance and to tweak those numbers if you feel you have a slow metabolism, etc.
Come talk to me after you've done depletion workouts (which is a different kind of pain than HIIT) on this calorie/carb intake.
It's a different beast.
From what I remember I never felt like vomitting but I did get light headed like a mother.
My training partner, who was doing the program with me, did vomit twice in week 1. After that he was good.
Depletion workouts suck no matter how you slice them.
If you say so...
I don't put time frames on such things. I just go until my body tells me it's time to change things or outside factors like a vacation or the like warrant a cut or something of that nature.
I'll have to send you some pictures of me at 10-11%. My abs aren't very visible at that stage. It's based heavily on genetics, unfortunately. For my abs to be exposed nicely, I need to be at a level of leanness that is not attainable year round. At least not a level I care to try and maintain year round.
On another note, I do understand why you set up the 2 year goal. Makes perfect sense.
Hard to say. Probably a combo.
I'm telling you... I'm lean to the extent you can see defined abs a vast minority of the year. I just don't care enough. I used to care a whole lot. But now I'm more in it to look decent, be strong, feel good, etc.
Not that there's anything wrong with being chiseled. It's just for me, what it takes to obtain that look, at least in my mid section, isn't worth it most of the time.
It's all about sacrifices.
Oh you don't have to sell me on that at all. Once per year I usually get nice and ripped. My desires change with the wind. Strenght and performance is always the foundation and physique enhancement is always a bug I catch now and again... hence why you find me cutting and bulking.
If all I cared about was strength, you'd rarely see me cut.
That's actually not too shabby with the weights.
In my experience there's not a lot of translation b/t db and bb work when it comes to benching. I used to have a training partner who would smoke me in terms of dbs. On bb though, I'd destroy him.
I've been benching heavy for a long while now and I can't say it's caused any problems to my joints. I do know, however, when to push it and when to back off.
And I'm not afraid to drop the bench from my programming for a while if my body is telling me too.
