Hi,
How can I estimate how many calories a 14 years old growing kids who
started a proper weight training program need daily?
I’ve been a suggested a method by Lyle McDonald that says you need 14
calories per pound of bodyweight for maintenance and 16 calories per
pounds of bodyweight for muscle growth
But does he need more because of bone and body growth other than muscle
growth?
Harris-Benedict method doesn’t seem to precise
Maybe I should first calculate the basal metabolic rate and then add for
the activity and muscle growth factor?
Any idea

Thanks a lot to everyone
Daniel

14-16 sounds too low. For an adult maybe. For someone his age I would think
22-28 cal/lb would be better.

Thanks for your answer
I've still some doubt
I calculated his Basal Metabolic Rate at:
http://www.exrx.net/Calculators/CalRequire.html

if I set Resting Hours at 24 (resting metabolic rate) and I
change the age between 14 and 30 the difference is just 100
That means that the difference between his resting metabolic rate and
a 30 years old metabolic rate is just 100 calories
So, his exrx calculator wrong ?
If not, what the difference between 14-16 and 22-28 account for ?
Not only age, it seems age only results in a difference of 100-150
calories more or less

Thanks again
Daniel

Hi Daniel,

I'm not the best person at all to answer your question. My figure was a sum
of what I think a good basal figure might be + enough calories to support
normal physical growth of that age and allow for muscle growth & large
amounts of physical activity. That's the scope of my answer. My figures are
not BMR.

Thanks,

-Chad
