Thats great thanks for that James, crazy how many different ways there seems to be of calculating it.
I will probably carry on using the Katch-McArdle formula as I like that fact that it takes body fat in to account.
I currently use the following modifier to estimate maintenance calorie requirements
1.2 Sedentary: Little or no exercise (desk job) 1.375 Lightly Active: Light exercise 1-3 days per/wk 1.55 Mod. Active: Mod. exercise 3-5 days per/wk 1.725 Very Active: Hard exercise 6-7 days per week 1.9 Ext. Active: Hard exercise/endurance + Physical job
I then work out a goal specific calorie target (fat loss or weight gain) by either adding or deducting 17.5% of their maintanance calories.
I use this to give my PT clients an idea of how many calories they should be consuming (I do always mention that they should see a dietitian if they want a more accurate breakdown or meal plans).
Obviously I know using the above calculations is never going to give a truely individual or incredably accuate target but can you spot any glaring errors.
I'm being cheeky by asking but hey if you don't ask you don't get
