hey everybody Dr o here in this video

I'm going to talk about the U.S Navy

body fat calculator which to me is the

simplest way to estimate or determine

your body fat percentage from home all

you need is a tape measure and maybe a

friend to help you with a couple parts

of this so the accuracy rate in some

studies the bot U.S Navy body fat

calculator is accurate within three to

four percent which is really amazing I

mean dexa scans underwater weighing

you're looking at five or six percent so

even if it's not even if it's in the

same ballpark as a dexa scan it's it's

cheap convenient you can do it on a

regular basis I really like this so all

you need to do is take proper

measurements then you have to have a

calculator to actually input the numbers

and I'll show you where I like to do

that so the measurement guidelines

that's what I want to go through here

first you can properly measure yourself

so you need to know your height this

should be barefoot and then I recommend

taking your height three times and then

averaging that right just to make sure

it's right have somebody help you with

this one if you can you know we with the

kids we do it on the wall and those kind

of things but find a really good way to

measure your height get it done at the

doctor's office that's fine but make

sure you're barefoot okay now the

measurements for a meal you need to take

a measurements at the neck and at the

waist and for females it's neck waist

and hips so for the neck it's the same

for both males and females you can see

an actual picture here of a naval

instructor doing this uh the tape the

measurement needs to go around the neck

right below the larynx right below the

Adam's apple so that's where you want to

take that measurement and I always

recommend taking two or three

measurements and then averaging them so

that's going to be you want to make sure

you don't get a bunch of neck muscles

there so you want to be right right at

that spot not too low but then not at

the Adam's apple or and definitely not

above it and you shouldn't be crushing

someone's windpipe there so that's the

neck right below the larynx or the

atom's Apple

the waist is going to be different for

males and females so at at the it's at

the level of the belly button for males

for for most meals you put it right

there at the level of the belly button

and it's the narrowest part of the

abdomen for females because we're going

to be comparing the the waist and the

hip so that's usually going to be midway

between the bottom of the sternum and um

between the belly button so it's gonna

be a little higher like you see here in

this picture so for a male you take the

waist measurement at the the navel at

the belly button for a female you find

the narrowest part of the abdomen the

key for both though is you take it after

a normal relaxed exhalation don't be

sucking your gut in but don't be forcing

it out either so take a few quiet normal

quiet breaths at the end of a normal

exhale is when you want to take your

measurement and take a couple of them

and average amount

all right so for for females only you

use the hip so this is uh specifically

how it says in the U.S Navy's um

information about this I'll read it the

hip tape measurement consists of the

circumference of the waist at the level

of the greatest protrusion of the

gluteal muscles so for most people

that's going to be at the widest point

of the hip the greatest protrusion of of

the buttocks of the gluteal muscles so

you find that widest area there and then

you take those calculations all right so

now if you're a male you have your neck

measurement and you have your waist

measurement a female you have your neck

your waist and your hip now you're ready

to actually run the numbers so I'm going

to show you how to use the calculator

that I use from Legion

so I'll take you there now

okay Dr o here so I'm going to walk you

through how I take my calculations for

the U.S Navy body fat calculator and

where I input them which is here on this

Legion site so I have no affiliation

with them I do buy someone like their

pre-workouts and different products I

like them but that's where I found the

tools so this is not an advertisement in

any way just a great tool so you see I'm

at legionathletics.com tools there or

slash tools yeah you can see it there so

you see they have a lot of different

tools

but the one we're going to go to is the

body fat percentage calculator so I'm

going to click on it here

and then here you're going to see where

you can read through all this if you

want but you're going to see that I can

let's say so I'm a male

I put 40 40 year old male that weighs

250 pounds but notice here's what we

have to do the originally it's the skin

fold so you click on this and you go the

Navy tape measure method and that's

going to change things and then you have

your your height

so you choose the height here I'm just

whatever so six four you choose a your

neck measurement remember that's going

to be right below the larynx let's say

that it's uh when you see how the

numbers are changing so we'll say it's

22 that's a very very big neck and the

abdomen is we'll go to 38. so it is

estimating yeah this is bad 8.59 body

fat you see here the lean mass versus

fat Mass but notice as you change these

measurements it's going to tell you your

body fat percentage so the key there is

to make sure you click on the Navy body

fat measurement but now

watch this as I click to a female you

see an extra category has now been added

so if we have a 250 pound 40 year old

female that says five five and then you

input your different numbers so I'll

just leave them here so a 14 inch neck

28 inch waist 36 inch hips would put you

at a 21.8 percent body fat measurement

so that's the key you go to the tools

section you find their body percentage

calculator make sure you switch right

here to the Navy tape measure method and

then you input all the information that

you have and it's going to give your

body fat percentage what else is it

going to tell you it tells you kind of

where you would fit from a BMI

standpoint there's a lot of extra

information down here if you want to go

through that but I just I just wanted

you to have a home where you could you

could calculate the measurements that

you took okay I hope that this helps all

right so hopefully that showed you how

to use this calculator I showed you with

both males and females but while you're

there why you're on their website and

again this is not an advertisement for

them I buy products from them but I have

no affiliation this is how I found the

calculators they have in their tools

section but while you're there they also

have pictures here male body fat

percentage pictures and you can and you

can kind of see which one you fit

closest to and then here we have same

thing with females so you can use this

it can get you in the right ballpark

it's certainly not going to be perfect

but the numbers you get from the U.S

Navy body fat calculator should be

somewhat similar to the pictures that

you see here

all right so why should we care right

why does this matter why does it matter

knowing your body fat percentage why

does it matter to know your body

composition you know why do I do things

like get my dexa scans done and these

types of things General Health

Information absolutely but goal setting

right you know you're watching this

because you you probably want to lose

some weight so for goal setting purposes

but the main reason I like it is because

once you know your body fat percentage

you can get better information about

your basal metabolic rate and your total

daily energy expenditure people are

always going going online and using

these calculators if you don't know what

your body fat percentage is it has to

give you a wild estimate of what it

thinks your energy energy expenditure

and your basal metabolic rate are if you

know your body fat percentage or get

even close it can really really help you

right because two people could be could

be six feet tall and weigh 250 pounds

one could be solid muscle and one could

have fifty percent body fat so if you

don't know those numbers how does it

give you the right information

so and then to me it's especially

important that you know this because if

you know how many pounds of fat you have

on your body you can determine how much

energy your body can provide on a diet

so it can help you determine what your

calorie Target should be if you're on a

diet and it should also be able to help

you monitor to make sure you're not

being too aggressive on your diet and

you're not losing too much lean mass on

a diet because you want to make sure

that you're using losing fat not just

losing weight and you want to make sure

that you're losing a as much fat as

possible while losing as little lean

tissue as possible you know like I

always say you're better off losing

nothing than losing muscle so that's why

I think this stuff is important so I

hope that this helped you have a

wonderful day be blessed
