bioelectrical impedance accuracy reddit

Ideally make sure when you take the reading is consistent (like 7am every Monday morning). BIA estimates body composition using equations that calculate the difference of electrical conductivity among different tissues (e.g., bones, adipose, muscle, cartilage) 17. 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. Bioelectrical impedance analysis (BIA) is a relatively simple, quick and non-invasive technique, to measure body composition. Aim: The aim of this study is to compare total weight, % body fat (% BF), fat mass (FM) and fat‐free mass (FFM) measured by bioelectrical impedance analysis (BIA) and dual‐energy X–ray absorptiometry (DXA). 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). Trainer and B.S. There are various ways to measure the percentage of body fat, and some are more high tech than others. Really I'm just kinda curious how far off this diet may be throwing these measurements in comparison to what I was before I started. The problem I see is that, in the real world, these protocols aren’t followed and this will throw off the measurements completely. James Krieger, "The Pitfalls of Bodyfat “Measurement”, Part 4: Bioelectrical Impedance (BIA)". Basically, BIA is quick and easy. New comments cannot be posted and votes cannot be cast. Such scales work with the help of sensors underneath your feet that use bioelectrical impedance… 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. The purpose of this review is to examine the theory and assumptions that may limit the use of bioelectrical impedance analysis in such individuals. If strict hydration protocols are adhered to, BIA is actually reasonably accurate. A … Pretty much everything that’s been said so far is true. doi: 10.1097/MD.0000000000019103. Eighty-two female volunteers ranging from 19-67 years (31.96 ± 1.39) enrolled Keto likely makes these readings even more inaccurate. G-SH, HC, and S … Bioelectrical Impedance Analysis (BIA) BIA is able to make an estimation of body composition (e.g. Accuracy augmentation of body composition measurement by bioelectrical impedance analyzer in elderly population Medicine (Baltimore) . My fitbit aria uses bioimpedance and told me I'm at 10%. Bioelectrical impedance analysis (BIA) is a safe and cost-efficient method that avoids exposure to radiation and is used to measure body composition. 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. 2020 Feb;99(7):e19103. 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? Accuracy augmentation of body composition measurement by bioelectrical impedance analyzer in elderly population. I have this scale, its only accurate to track your weight, thats it. The partic- I've lost 3% body fat in 5 months which meets my goals (slowly cutting while getting back in shape). Most of the accurate methods for measuring body fat are limited to the research laboratory or are extremely expensive. I got one of these awhile back to somewhat monitor my body fat percentage, way before I started the Keto diet. But is it accurate? Body fat (adipose tissue) causes greater resistance (impedance) than fat-free mass and slows the rate at which the current travels. Bioelectrical impedance (BIA) can potentially meet these needs but its validity in active individuals is not well established. My styku scan read that my BF was at 9%. If strict hydration protocols are adhered to, BIA is actually reasonably accurate. How inaccurate are "Bioelectrical Impedance Method" body fat monitors while on Keto? Press question mark to learn the rest of the keyboard shortcuts, "The Pitfalls of Bodyfat “Measurement”, Part 4: Bioelectrical Impedance (BIA)". The error rate got as high as 8%, and that’s for detecting a change over time. And the more data points you have, the more accurate the average will be. I know it's not accurate, but is it consistent enough to track changes? BIA can vary widely with changes in hydration. It is based on the difference in resistance when an electrical current is conducted through fat or lean components of the body.

The readings can be overestimated by around 40% for men, 55% for women, according to wikipedia (citing an exercise physiology book). Yes and no. The problem I see is that, in the real world, these protocols aren’t followed and this will throw off the measurements completely. 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. 2011 Apr;25(4):1040-5. doi: 10.1519/JSC.0b013e3181cc224a. The electrical impedance (Z) consists of two components, resistance (R) and reactance (Xc). Medicine. Accuracy can also vary depending on various factors, including gender, body type, and age. The Ketogenic Diet is a low carbohydrate method of eating. 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, and 12% body fat. 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). So if it says you have a body fat of 20% might actually only be at 14%. You’ve been losing fat. Again, you can see BIA had the biggest spread of all the methods, even bigger than BMI. Percentage of body fat is strongly associated with the risk of several chronic diseases but its accurate measurement is difficult. So one could lose 4% body fat, yet BIA might show an increase in body fat of 4%. Thanks a bunch!
