In the HOW TO DO A CKD thread by Dr. X, he recommends using body weight X 12 to get BMR.

A guy that's 170lb would get a BMR of 2040 using this method


I've always heard of using the benedict formula to find BMR

QUOTE
Men: BMR = 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) - ( 6.8 x age in year )


Then multiply that BMR number by a factor of 1.2 to 1.9 depending on activity level, to get effective maintenance BMR.

1. If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2
2. If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375
3. If you are moderatetely active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55
4. If you are very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725
5. If you are extra active (very hard exercise/sports & physical job or 2x training) : Calorie-Calculation = BMR x 1.9




Okay so two questions:

1) should a person use their body weight or LBM for these formulas? I've heard if you're over 20% BF you shouldn't use body weight...

2) is there a benefit or problem using the benedict formula in conjunction with CKD?

It really dosen't matter what you use. Once you start then you will be adjusting on a regular basis, you just don't want your cals to low.
What your basically are looking for is a starting point.
