MarkS - 25 Apr 2005 12:31 GMT Hi all, I was wondering. What is the best way to lower your bodyfat %? I purchased one of those hand held electronic body fat meters and I keep getting about 24%. I am a 36 year old male 6'1, 180lbs. 2 years ago I was 246lbs. I run about 15 miles per week spread over 4 runs. Any suggestions? mark
Ignoramus8409 - 25 Apr 2005 13:45 GMT Check out misc.fitness.weights, they discuss these issues all the time.
Briefly, the answer is lifting heavy things as well as proper dieting.
Your meter's reading is a little surprising to me.

MarkS - 25 Apr 2005 15:01 GMT Now that you say that, I had it checked at a 5k event by a doctor with a pinch tester, he read 14.7%. In my opinion that may be a little low, but more along the lines of correct. Oh well, what do you want for $15. Mark

You can use the "Navy" method to compare with your meter. It only requires a couple of body circumference measurements, and should be reasonably accurate. If the Navy method yields a substantially different result, your body fat meter may be defective. FWIW, electronic body fat meters can be influenced by hydration levels, and will give different readings depending on time of day.
I've included the Navy method of body fat analysis in the free trial version of my "WeightWare" program (http://www.WeightWare.com), or there's an online version of it here http://www.he.net/%7Ezone/prothd2.html (just ignore that site's odd recommendations for "Ideal" weight).

I still don't understand the weight vs BF relationship, according to the Navy method I have 25% BF & it should be 22%. According to the BMI calcs, I'm not overweight. So I'm not overweight but I'm still fat, how can this be?

Are you sure you're not confusing body fat percentage with Body Mass Index?
The Navy method has a margin of error, like all body fat estimation techniques, which I think is around 3-4%. Try measuring every week or so and taking an average over the month.
The Navy method is also quite sensitive to measurement errors, so you need to be careful in how you measure. The specific procedures for taking the measurements can be found in this document: http://www.dtic.mil/whs/directives/corres/pdf/i13083_110502/i13083p.pdf
Alternatively, you may simply be a statistical "outlier". If you go to a gym, you can probably get a body fat test using bioelectric impedance, or skin calipers, and compare those results to the Navy method's.
FWIW, it's definitely possible to be "normal" per BMI, but have too much body fat...When you look in the mirror, do you see more muscles, or more fat? When you jump up and down naked in front of a mirror, is there a lot of "jiggling" (besides the obvious bits that are supposed to jiggle :-) ).

I find measuring a little tricky, I'm never sure that I have the tape in the right place, wonder whether it's too tight, etc. It's nowhere near as easy as stepping on a scale ;-)
I have thought of buying a scale with BF monitor built-in but I've heard they're not accurate.

The 'obvious' bits are not too jiggly (or obvious, for that matter), I'm rather skinny on top with a heavy bottom where I see no muscle, just fat ;-(
Guess I'll have to keep working on that part ;-)

The specific procedures for taking the [quoted text clipped - 7 lines] > I have thought of buying a scale with BF monitor built-in but I've heard > they're not accurate. I have one of the Tanita scales that shows BF. But, it can vary quite a bit (3-5%) depending on time of day and hydration status. It also seems like I'm somewhere between the "normal" and "athlete" settings. In "normal" mode, it shows me a little higher than what the Navy method shows (~13%). On "athlete" mode, it says I'm in single digits (LOL).
As long as I pick one mode, and always take the reading around the same time of day it's consistent, so it's a good way to compare over time (even if it's not 100% accurate).

(whoops....my bad).

Trying too hard for "perfection" can be a starting point for eating and exercise disorders.

Yes, same principle as with your weight, i.e. consistency more important than accuracy. I'll see how much those Tanitas cost.

When I first read 'dysmorphia' I was going to say 'yes, that's it', I thought it meant having a badly proportioned body with all the fat going to one place.

My Tanita scale is several years old, but it's similar to this one: http://tinyurl.com/49swe
I've been very happy with it, though I don't use the body fat feature very often (I prefer the Navy method, and track my circumference measurements along with the body fat estimate). Most of the Tanita scales are accurate to 0.2 lb, and very consistent when weighing - I can step off, and back on, and usually get the same weight both times (and nearly always get the same weight 2 out of 3 times).
There's also a cool-looking scale from Germany that's supposed to be accurate to 0.1 lb, even if you're standing on one foot (http://tinyurl.com/3t6kt ). But, it doesn't have the body fat feature, and it's pretty expensive (like most highly engineered German products).

I saw a documentary on eating disorders a year or two ago, and one of the people in the program was a 45-year old male who exercised 2-4 hours per day, and was obsessed with eating "healthy". He insisted that he was fat, and needed to lose more weight, even though he looked like a concentration camp survivor. It was strange listening to him describe his own body, as it was so different from what he actually looked like...just goes to show that it really can manifest at nearly any age (and gender).
As much as I enjoy being thin (mostly because it helps when cycling), I could never do the anorexia thing...that would mean giving up chocolate, and without that I don't think life would be worth living. Family and friends know that if I ever lose interest in chocolate, or become interested in golf, an intervention is warranted :-).

Polar Light - 26 Apr 2005 23:29 GMT Gary,
Thanks for the tips, I'm looking at the URLs for the scales.
Oh, and I still like chocolate ;-)

I would suggest to return the device back to the store, if you can. It is too inaccurate to have any value.

Renegade5 - 29 Apr 2005 12:49 GMT >Hi all, >I was wondering. What is the best way to lower your bodyfat %? Good question! Some experts say that the best method is through diet. Others say exercise. Still other say a combination of diet and exercise. Some say 'cardio' and some say 'resistance'. I think the simple truth is that they all work, but what works *best* probably depends on the individual.

Better would be a Tanita or Phoenix body fat scale (unless you are an athlete)... but you need to follow their directions for measuring body fat precisely to get an accurate reading (ie. hydration, exercise, eating, time of day are all factors - the instructions with the scale tell you when best to take your reading ).
