Rosbif: To work out your BMR (Basal Metabolic Rate) do the following calculation, workout your RMR and then multiply your activity ratio:
RMR (Resting Metabolic Rate) = 66 + ( 13.7 x weight in kilos ) + ( 5 x height in cm ) - ( 6.8 x age in years )
This is what your body would need if you were sedantry and just needed to tick over (a bit like a car engine sat on the drive idling without revving the engine).
Now you need to work out your daily energy expenditure
So you take your RMR and multiply by one of the following (be honest to yourself):
a) If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2
b) If you are lightly active (light exercise/sports (yoga, calenetics, light walking etc..) 1-3 days/week) : Calorie-Calculation = BMR x 1.375
c) If you are moderately active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55
d) If you are very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725
e) If you are extra active (very hard exercise/sports & physical job or 2x training) : Calorie-Calculation = BMR x 1.9
Personally despite my hardcore gym nature I'm around c) maybe flitting up to d). However very much closer to c). It's important that you're honest.
500kcals a day over your BMR will in a week on average get you an extra lb. However unfortunately, it often isn't 100% muscle
Conversely to get rid of of 1lb that's 3500kcals deficit you need. In plain amount of joules/energy required to burn 1lb it's pretty much bang on 3500kcals anyway!
You don't have to count calories really, just eat well, however, it's important to know where your body is at. ?Most people surprise themselves. Mine works out to be around 3500kcals.
So for you rosbif your RMR would be (at the age of 34 and with the stats you've given me):
RMR = 1793.527273
1.375= 2466.1
1.55= 2779.967273
1.725= 3093.834545
So your guestimate wasn't too bad!
You haven't got much fat on you at all. I think you could safely train to add some mass without much worry. You're happy with your diet and not eating crap - that's the number 1 battle. Now you just need to get a good weight lifting program to harden up the muscles you have and add a bit of size to you. Adding 10lbs of lean muscle is
not easy, but achieveable this year if you're ready to do it.
Yabsley - 85kg at your height seems a little on the slim side - though perfectly health at the same time - taking muscle mass and fat aside that's about average weight for your height. What are your goals in terms of performance and aesthetic value?
I agree with you entirely that there have been some amazing threads and posts and achievements on here. That's why I love this forum - it even helps to motivate me, and when I get in a sulk about my physique and performance it often helps pick me right up again!
