bioelectrical impedance accuracy reddit

There are various ways to measure the percentage of body fat, and some are more high tech than others. 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%. Basically, BIA is quick and easy. New comments cannot be posted and votes cannot be cast. I could be wrong on that though. 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. I'm curious though, since on the Keto diet people are naturally inclined to be more dehydrated, does this effect these types of monitors heavily? I've lost 3% body fat in 5 months which meets my goals (slowly cutting while getting back in shape). Accuracy can also vary depending on various factors, including gender, body type, and age. go by how you feel, perform, look, sleep, think etc. The purpose of this study was to examine the accuracy of percent body fat estimates from seven different bioelectrical impedance analysis (BIA) models and a seven-site skin fold formula (SKF) compared with air displacement plethysmography (ADP) in females. Bioelectrical impedance analysis (BIA) is a relatively simple, quick and non-invasive technique, to measure body composition. 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. Maltron International is the world’s leading manufacturer of Bioelectrical Impedance Analysers (BIA) and Electrical Impedance Tomography (EIT) imaging technology. It can, and typically is inaccurate. But is it a good idea? 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. I have this scale, its only accurate to track your weight, thats it. 2020 Feb;99(7):e19103. I'm a male and I started keto at 195 lbs and roughly 20.5% body fat according to that little device. Since then, I've lost 20-ish pounds and it has me at 18.5% body fat. The problem I see is that, in the real world, these protocols aren’t followed and this will throw off the measurements completely. Over the course of time you can graph the chart and see if there’s a trend, if there is tada! 11 ($45.11/Count) $79.95 $79.95 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. Comparison between two methods of bioelectrical impedance analyses for accuracy in measuring abdominal visceral fat area. If you want it to be accurate intake the same amount of salt and water. But is it accurate? Yes and no. The electrical impedance (Z) consists of two components, resistance (R) and reactance (Xc). Bioelectrical impedance vector analysis (BIVA) derived from resistance and reactance measurements is a method used to identify nutritional status and to monitor hydration status in different populations [1,2,3].The BIVA is able to identify differences in the hydration status in which the resistance/height axis (long vector) is observed and in the components of body composition, such as … Pretty much everything that’s been said so far is true. "Comparison of three bioelectrical impedance methods with DXA in overweight and obese men" J Strength Cond Res. Pateyjohns IR, et al.

Cookies help us deliver our Services. You’ve been losing fat. My styku scan read that my BF was at 9%. I think my understanding is that if you are dehydrated, it will show you as a higher BF%? It measures body fat accurately in controlled clinical conditions but its performance in the field is inconsistent. The purpose of this review is to examine the theory and assumptions that may limit the use of bioelectrical impedance … Bioelectrical Impedance Analysis. If strict hydration protocols are adhered to, BIA is actually reasonably accurate. Reactance is a measure of BCM and resistance a … resistance of the body and the accuracy of BIA. It is based on the difference in resistance when an electrical current is conducted through fat or lean components of the body. Herein, we evaluate the accuracy and reliability of multifrequency bioelectrical impedance analysis (BIA) to assess skeletal muscle mass (SMM) in the colorectal cancer … This is something I’d do if I was trying to cut bf% It’s excessive, but I like excel. Again, you can see BIA had the biggest spread of all the methods, even bigger than BMI. 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. And the more data points you have, the more accurate the average will be. Even the trend is wrong as it fluctuates a lot. In BIA, a weak electric current flows through the body and the voltage is measured in order to calculate impedance (resistance) of the body. 2016 Jul;36(7):663-70. doi: 10.1016/j.nutres.2016.04.003.
