BMI and BF% and impedance level oh my...

Confuzzled4ever

I got on this scale thingy that tells you all your percentages

height was entered as 5 10 even though I told her 5 9 so these numbers might be a little off..
Age: 34
BMI 28. 1,
BMR 1678 kcals,
Body fat% 34%,
fat mass 68.01 lbs,
my bones and such weight 34 lbs.,
weight 196. target weight: 173,
target bf 26%,
fat to lose 23lbs..
impedance level of 400.. which has something to do with hydration level (which equates to 48% which they said it a good percent.)..

Anyone have input on what I do with these numbers now? Or have any input on what they really mean? They wouldn't talk to me unless I signed up for thier "progam" which involved manantory diet pills/vitamins/suppliments, following thier structered meal plan and going for "checkups " often. no thanks..

I just changed my calorie goal to 1600 and planned today to meet that number..

They recommended 20/60/20 (carbs/protein/fat) for macros which seems ludicrist to me. i've got it at 30/45/25


Also.. i think i have too much dairy in my menu today.. is there really such a thing or is that just a myth?

60% protein is excessive, are you sure ?? 45 is over most recommendations too.

The fat percentages and stuff look broadly sensible.

BIA isn't very accurate at all...

With respect to the BI scale, take the results with a grain of salt. Think about it this way, how does ones age, weight, height or activity level really affect ones BF level? All that data is entered because in addition to the impedance numbers it gets it is also performing a boat load of calculations based on a vast array of people. If the device were 100% accurate it would have no need for that data. The scale will show a trend, but the numbers are not incredibly accurate. If you keep using it, it is important to try to do so at around the same time of day. They are very sensitive to the water on board. I can get mine to swing up to 10% between morning and night. Look to the mirror and measurements. They don't lie.

Bone and organ mass is unimportant. You are fully grown so they will not change for the purpose of your mission. Impedance level is also of zero importance. BF and LBM is really all that is of interest. That was a huge sell job on their part. I would never sign up with someone that tried that crap either.

If 34% is your real BF your lean mass is around 129lb. My guess is that might be a little on the high side, but go with that for now.

As for your diet, I too think 60% might be a high. Aim for 1g/lbm protein, 0.4g/lbm fat and fill the rest with carbs to hit whatever calorie target you go for. You need to pay attention to what your body tells you and adjust when and as needed. Time cures all.

Here is an easy macro calculator that might help: http://iifym.com/IIFYM-calculator/

You are doing good.

I think they only entered my height weight and age into the thing before it calculated anything. They were suprised that my hydration level was "good"..

I honestly think that BF% is high.. dont' get me wrong.. i'm rocking fat around the middle still and probably some still hanging onto my thighs.. I did some online calculator and it told me 164 is my LBM. which by your suggestion means i need to eat 164g of protein. That's an aweful lot. But you're suggesting my LBM is 129.. which sounds better esp when I think about hitting that protein goal.

So then how would I get an accurate BF% and LBM goal without having to buy a scale?

1g/lbm protein, 0.4g/lbm fat

so. using the 129 that would be 129g of protein and 52g of fat.
that is something i can probably do. Actually I think my plan for today falls close to that..

Ok..so If I am looking to measurements, what is a good measurement for me to aim for? on 4/7/13 my belly was 41.5 inches my hips were 44inches and my chest was 43 inches.. (guess I need to measure again huh. lol been awhile) Is there a "healthy" or "ideal" measurement to aim for? I imagine it's all personal and individually specific..

60% protein is excessive, are you sure ?? 45 is over most recommendations too.

45% of protein is still high? I initially had it set at either 35 or 40%. I'll be happy to put it back to that. It's hard to eat that much protein and I really do want to stop using powder and bars and stuff.

ETA: I lied.. i'm current set at 30/40/30 carbs/protein/fat

I don't know what BIA is???

I went to the place for answers.. all I got were more questions.. lol

A woman at 29 BMI (the right number) and 34% fat sounds about right to me, maybe a bit low. If you were at 22 BMI you might be 20% fat......

So 22 BMI 20% fat LBM = 119 lbs of 149 lbs total weight. If you're currently 119 lbs of LBM then that's 39.25% fat now.

Waist to hip ratio <0.85 or waist to height <0.5 ? off the top of my head those are "good" numbers. So waist of 34.5 or less based on your height. Sounds sensible.

Over 35% of calories as protein is generally written up as "excessive" for normal people. A male body builder might be over that but it's not a nutritional necessity or desirability. High protein = High growth factors = more disease risk, much of it is wasted as fuel as you can't use that much protein unless you're the above high testosterone case.

BIA is Body Impedance Analyser - the measurement used to estimate your body composition. It's probably adequate for you but some 10% fat gym bunny would ***** about it.

Just like any non-medical measurement of BF, that depends. A newer model BIA measurement is likely to be much more accurate than calipers in the wrong hands. Like all technology, bioimpedence is constantly improving.

My new scale was very close to my DEXA scan results.

So.. if i'm understanding you..

119 is probalby closer to my LBM (149 is??? my ideal weight? seems a bit low.. honestly.. bit i could be wrong. )
I'm probalby 39% body fat right now.. not 34%
My waist should be around 34.5 inches.. (the measurement i initally gave was my measurement across my navel, my natural waist is much smaller)
Set my protein to 35%

Did I get the points you were trying to make?

you did.
