If you are going to use BIA for tracking body composition over time, I recommend very long time intervals between measurements (at least 3 months, but 6 months is probably better), as the error rate for BIA can be larger than the changes in body fat in you see. I have this scale, its only accurate to track your weight, thats it. It can, and typically is inaccurate. Only if you can control all the confounding errors (hydration, skin conductivity, etc).... and the answer is probably "no". Bioelectrical impedance analysis (BIA) is a technique that has proven to be safe, generally acceptable to patients, and easy to use [109,110].BIA is used for determining fluid management and increasingly for … The principle of BIA is to determine the electric impedance of an electric current passing through the body [15]. The problem I see is that, in the real world, these protocols aren’t followed and this will throw off the measurements completely. It measures body fat accurately in controlled clinical conditions but its performance in the field is inconsistent. BIA can vary widely with changes in hydration. It is not consistent over time, no. Accuracy augmentation of body composition measurement by bioelectrical impedance analyzer in elderly population Medicine (Baltimore) . The way a scale like this works is to use hydration and weight to estimate body fat percentage(some scales will ask about age, height and gender also). go by how you feel, perform, look, sleep, think etc. Most of the accurate methods for measuring body fat are limited to the research laboratory or are extremely expensive. G-SH, HC, and S … Accuracy can also vary depending on various factors, including gender, body type, and age. Bioelectrical impedance analysis (BIA) is a method for measuring body composition based on the rate at which an electrical current travels through the body. A … If strict hydration protocols are adhered to, BIA is actually reasonably accurate. Reactance is a measure of BCM and resistance a … PSA: Bioelectrical impedance analysis overestimates body fat while on keto Tried to post this in r/keto , but their automod deletes everything I post. "Comparison of three bioelectrical impedance methods with DXA in overweight and obese men" J Strength Cond Res. Press question mark to learn the rest of the keyboard shortcuts. 2011 Apr;25(4):1040-5. doi: 10.1519/JSC.0b013e3181cc224a. So if it says you have a body fat of 20% might actually only be at 14%. Bioelectrical impedance analysis (BIA) is a promising tool in the evaluation of body composition in large population studies because it is fast, is inexpensive, and does not require extensive operator training or cross-validation. Trainer and B.S. I got one of these awhile back to somewhat monitor my body fat percentage, way before I started the Keto diet. "Comparison of three bioelectrical impedance methods with DXA in overweight and obese men". Bioelectrical impedance is the process of sending a low-level electrical current through the body. Cookies help us deliver our Services. /r/keto is place to share thoughts, ideas, benefits, and experiences around eating within a Ketogenic lifestyle. The partic- Author links open overlay panel Kyeong Seon Park a b 1 Dong … Over the course of time you’ll hopefully see a trend, even if the error percentage is there. Over the course of time you can graph the chart and see if there’s a trend, if there is tada! The purpose of this review is to examine the theory and assumptions that may limit the use of bioelectrical impedance analysis in such individuals. Eighty-two female volunteers ranging from 19-67 years (31.96 ± 1.39) enrolled How to cite this article: Fang WH, Yang JR, Lin CY, Hsiao PJ, Tu MY, Chen CF, Tsai DJ, Su W, Huang GS, Chang H, Su SL. 2020;99:7(e19103). 2020 Feb;99(7):e19103. It's highly inaccurate, and can swing both ways (over and under estimating) depending on how much water you drink, salt intake, how long you've been doing keto, if you exercise, and probably a ton of other factors. In my opinion, the best way to get an accurate reading would be to take 2-3 readings a day, every day, graph those percentages on excel and takes averages on a daily/weekly/monthly basis. I've lost 3% body fat in 5 months which meets my goals (slowly cutting while getting back in shape). Yes and no. If you have a similar electrolyte concentration you will have a similar impedance. For example, if the scale tells you ,you weight 153lbs and 128lbs of lean body mass, it'll say that even if you put on 5lbs of muscle and then loose some fat. My styku scan read that my BF was at 9%. So one could lose 4% body fat, yet BIA might show an increase in body fat of 4%. Medicine. 2016 Jul;36(7):663-70. doi: 10.1016/j.nutres.2016.04.003. I was just kind of curious if I'm actually doing a little better than that so far, but I know I still have more to lose. I am interested in tracking my body fat percentage, to that goal I was thinking of buying a body composition scale(more specifically this one). Muscle is composed primarily of water and water is a conductor of electricity. Background. Again, you can see BIA had the biggest spread of all the methods, even bigger than BMI. Not really. This is something I’d do if I was trying to cut bf% It’s excessive, but I like excel. : BIA scales measure body fat by estimating the amount of … My fitbit aria uses bioimpedance and told me I'm at 10%. Yes and no. BIA is a method for estimating body composition. I think my understanding is that if you are dehydrated, it will show you as a higher BF%? (Redirected from Bioelectric impediance analysis) Bioelectrical impedance analysis (BIA) is a commonly used method for estimating body composition, in particular body fat and muscle mass. The electrical impedance (Z) consists of two components, resistance (R) and reactance (Xc). Bioelectrical Impedance Analysis (BIA) BIA is able to make an estimation of body composition (e.g. Yes it can be inaccurate up to 3ish% in either direction based on hydration status. Pateyjohns IR, et al. Comparison between two methods of bioelectrical impedance analyses for accuracy in measuring abdominal visceral fat area. METHODS Subjects Ten male subjects who were between 18 and 42 years of age participated in this study. I have a scale that calculates body fat % which I use every day. New comments cannot be posted and votes cannot be cast. The readings can be overestimated by around 40% for men, 55% for women, according to wikipedia (citing an exercise physiology book). In this article, we describe the range of … Purpose of review: Several factors limit the use of bioelectrical impedance analysis as a valid predictor of the amount of body fat in morbidly obese individuals. Body composition is an important component of an individual's health and fitness profile. The purpose of this study was to assess the accuracy of bioelectrical impedance analysis (BIA) in detecting percent body fat (%BF) changes throughout a physical activity intervention in previously sedentary, overweight men and women. You’ve been losing fat. The more water in the body, the less resistance the current will experience as it travels through the body. Accuracy augmentation of body composition measurement by bioelectrical impedance analyzer in elderly population. Averaging a month of readings shows overall progress with accuracy even if the absolute body fat reading is off. Looking at some "worst case" studies seem to show that the readings can be off by up to 10% actual body fat (the average for a group is ok, but individual readings are poor): Imp-SF and Tanita demonstrated little bias and may be useful for group comparisons, but their utility for assessment of body composition in individuals is limited. Percentage of body fat is strongly associated with the risk of several chronic diseases but its accurate measurement is difficult. 11 ($45.11/Count) $79.95 $79.95 The problem I see is that, in the real world, these protocols aren’t followed and this will throw off the measurements completely. PDF | Purpose: The aim of this study was to investigate the effects of exercise training on bioelectric impedance measurements. The Ketogenic Diet is a low carbohydrate method of eating. I got one of these awhile back to somewhat monitor my body fat percentage, way before I started the Keto diet. If strict hydration protocols are adhered to, BIA is actually reasonably accurate. Even the trend is wrong as it fluctuates a lot. Bioelectrical impedance analysis (BIA) is an attractive method for identifying sarcopenic patients in clinical practice because it provides an affordable, noninvasive test that can be completed within a few minutes during a clinic visit. ABSTRACT. I thought that maybe the other stats would change over time based on my body composition but they definitely don't. Pretty much everything that’s been said so far is true.

Some studies published in 2015 showed that bioelectrical impedance analysis is a fairly accurate method for estimating body fat. Maltron International is the world’s leading manufacturer of Bioelectrical Impedance Analysers (BIA) and Electrical Impedance Tomography (EIT) imaging technology. How inaccurate are "Bioelectrical Impedance Method" body fat monitors while on Keto? I could be wrong on that though. Bioelectrical Impedance Analysis. in exercise science here. resistance of the body and the accuracy of BIA. I know they aren't entirely accurate and are heavily based on how hydrated you are when getting results, I just wanted to use it as a rough estimate. Another factor that affects your health is overweight, since it is associated with diseases such as high blood pressure, dyslipemia (high cholesterol values) and increased insulin resistance. YOu'd be better off buying a cheap body measuring tape, and using the Navy Method. quantities of fat mass and fat-free mass) by running a small electrical current through the body. It varies quite a bit from day to day, but over 5 months if use, shows a solid trend line downward which is very accurate. But is it accurate? I know they aren't entirely accurate and are heavily based on how hydrated you are when getting results, I just wanted to use it as a rough estimate. Easy to use and portable, study sets in Bioelectrical Impedance Analysis are great for studying in the way that works for you, at the time that works for you. I spent 100 bucks on nokia body scale while its showing nice stats most of then are just vs. My BF is decreasing which is true but its showing me 10%now down from 12% last month in reality I'm 14-15%. James Krieger, "The Pitfalls of Bodyfat “Measurement”, Part 4: Bioelectrical Impedance (BIA)". In BIA, a weak electric current flows through the body and the voltage is measured in order to calculate impedance (resistance) of the body. The bioelectrical impedance scale They let you know what you’re made of. If you are over-hydrated it will read you a lower % and if dehydrated then will read you a higher %. By using our Services or clicking I agree, you agree to our use of cookies. I know it's not accurate, but is it consistent enough to track changes? Yes and no. So in the last two weeks I have been tested for body fat % by two different BIA (Bioelectrical Impedance Analysis) machines, both of which have clocked me in around 5' 9", 173 lbs, … Such scales work with the help of sensors underneath your feet that use bioelectrical impedance… Press J to jump to the feed. Bioelectrical impedance (BIA) can potentially meet these needs but its validity in active individuals is not well established. Scales that use Bioelectrical impedance are considered reasonably accurate for measuring groups, or for tracking body composition in an individual over a period of time, but are not considered sufficiently accurate … It's like the scale associate 153lbs with 128lbs of lean body mass. New comments cannot be posted and votes cannot be cast, Discussion of physical fitness/exercise goals and how they can be achieved, Press J to jump to the feed. Bioelectrical impedance is an accurate method to assess body composition in obese but not severely obese adolescents Nutr Res. A more practical way would be a couple times a week, or once a day, however often you want to, take the reading write it down and then don’t obsess about it. The error rate got as high as 8%, and that’s for detecting a change over time. Testing for Free Learn how to effectively carry out tests on your athletes without spending penny!
