Physical Activity Level

[Ianthe]

It is hard not to notice that each book has different numbers when it comes to PAL. The articles I found were very old (1985) so I decided to come here and ask the experts for help.

And for those who arent familiar with the designation, PAL is the number you multiply the BMR for to get the daily energetic needs.

The diferences I found were very big, a difference of 200 kcal, for example, isnt acceptable...

I know PAL is a very relative number but I NEED to know what numbers should I follow.

Thank you

hummm I forgot to look on Krause's book. There's a pretty good explanation there. I'm satisfied, thank you

That number multiplier is so inaccurate I wouldn't bother. Try and figure out your BMR add daily activity calories and then add exercise calories.

Is probably way more accurate that way.

Yup, try to do that to multiple people everyday for the rest of your life, then you'll love that number
I found the most aceptable way of doing it in clinical nutrition.

I guess if the clinical nutritionist doesn't care about their patients...

I think you'll soon find out that the university department you are in loves to teach, at the undergraduate level, these one size fits all methods. Let me guess, you are in something like:

Bachelor of Science in Kinesiology
BSc in Nutrition
BSc in Food Science

or something where you have to take a dietetic internship?

Esp. with the latter two they tend to be full of gross misinformation.

I don't know how it works there, I'm not american.

5 + 1,5 years at Sciences of Nutrition plus 2 years internship at a public hospital
I do care about my patients, but there are a lot more important things to take care of then geting the perfect outcome calories number, which wont ever be perfect. That's why we need tools, we cant spend 3 hours with the same person. And most of them dont give a damn about numbers and even wouldnt understand them, this is my work, not theirs. Of course I have to ask them everything they do daily and everything they eat, but they wont tell me 100% the truth because they dont know what is important to say, they forget and they lie. They're different, they have different tastes, different ways of seeing life, different bodies, different genetic and histories and diseases, they have their head made with myths and then wont accept you to change them, so you have think of alternatives, they have special needs (and they can even not know that) and this is what really matters. So if you're thinking I'll be a bad professional if I use the tools best acepted by the scientific community to make the best I can for my patient, I have to think you have no idea what is working with so many people a day and having to figure out what is wrong with them and what did doctors missed in the less time possible.

I didnt even mentioned what tool I was talking about, but gosh... You're already talking about "gross misinformation". If you think you do better, go tell it to your National Academy of Sciences, Institute of Medicine (IOM), Food and Nutrition Board and Health Canada. I'm sure they would love to welcome you. This isnt a competition, we're all here for the same thing.
