Sasha,
re: have you read the eBook yet?
not yet, but I plan to. If you can post its location you could save me some search time.
re: valid point about energy balance, but analysis is too simplistic
I was intentionally oversimplifying, that’s true, but it’s important to remember that if you stay in caloric deficit long enough you lose weight (hopefully fat), and if you stay in caloric surplus long enough you gain weight (hopefully muscle), no matter what your macronutrient mix is.
What I’m hoping to do is to improve my existing diet by borrowing some successful AD ideas. In some ways my diet is already similar to the AD, but one thing that’s different is that I’m an active cyclist, which means that I burn a lot of calories every day and I’m not concerned about eating carbs. My goal is to reduce my bodyfat down to 15%, which is only 3.5 lbs away, and then to build as much muscle as I can, esp. in my legs, without putting on fat.
Currently my diet is as follows: First, while losing bodyfat I want to maintain a caloric deficit of about 550 calories per day so that I lose about 1 lb per week. Second, I want to eat as much protein as I need to build maximum muscle. I don’t know how much that is, but from what I can gather it is about 1g/lb body weight per day. If you think it should be different, let me know. For me, that’s about 173g protein.
I have a hard time eating that much protein over 5 meals a day. I also need about 40g of fat each day for good skin and brain health, and to keep fully loaded with glycogen for cycling, I believe I need about 50% of calories from carbs. That makes 409 + 1734 = 1052 calories from fats + protein, plus another 1052 from carbs makes 2104, plus 550 for caloric deficit makes 2654.
The 12xbodyWeight heuristic for calculating RMR is pretty good, but it needs to be adjusted for body composition. More muscle, higher, more fat, lower. I believe that my RMR is about 1970 cal, so that means I need about 2654-1970 = 684 calories/day from exercise. At about 44 cal/mile on the bike, this means I need to ride at least 15.5 miles per day, or less on strength training days. For me, that’s easy.
So while in my fat reduction phase my plan is very different than the AD in that I’m not concerned about carbs, as I intend to burn them off by cycling my butt off anyway. Since calories are calories, it doesn’t matter to me if they come from carb sources or protein sources, as long as I’m in caloric deficit.
When I get to my muscle building phase, which I expect to begin at the end of this month, then I will need more guidance from the AD. My previous attempts to gain muscle gained a lot of fat, too (which is what I’m working off now). Between now and then I’m spending some time in the gym and getting my body adapted to lifting again.
How can I adapt and improve what I’m doing using principles of the AD?
