CKD Parameter Calculator
This page helps you calculate various things about a Cyclic Ketogenic Diet (CKD)
put it here. After setting up your input parameters and running the script, a new
page will open with your CKD information - including suggested macronutrient
breakdown during the Ketogenic phase of the diet and the Supercompensation (carb-up)
phase of the diet. The breakdown is done for different calorie levels based on
body weight. You can print the parameters for future reference.
Sean Scoggins -- This page was his idea. Sean created the original CKD
Parameter calculator using a CGI program written in C. He also wrote the original
cover page (what you are reading right now.)
Lyle McDonald -- The formulas used to calculate these numbers were culled
from his many informative posts to Dave Skinner's Lowcarb+Exercise mailing list.
Lyle writes a very good nutrition article called Nutrimuscle at
This program resulted from the Lowcarb+Exercise mailing list, which you can
sign up for, if you are interested in
Lowcarb dieting and training topics.
This page is constantly evolving, so if you have ideas for things to
add/change/remove/etc. please let me know.
If we could get all the formulas Lyle kindly keeps posting (and reposting) to the
list in one place, it would be easier to point people with questions at the right
(Netscape Navigator/Communicator or
MS Internet Explorer) in order for this
- Post the actual formulas used for the calculations.
- Show daily and weekly caloric deficit based on inputted maintenance calories.
- Allow similar calculations for different diets.
Follow the steps below, set your input values, and hit the button! Note: Parameters with a gray background are not needed to run the CKD Calculator. They are only needed for the Body Fat Approximation.
