What's the most accurate way to measure body-fat at home?
Some byopsias.
What is that?
What's the most accurate way to measure body-fat at home?
Not exactly the sort of testing one does at home.mvsf1 said:A biopsy is a medical test involving the removal of cells or tissues for examination. It is the medical removal of tissue from a living subject to determine the presence or extent of a disease.
You could also detect how many fat the tissue has.
Not exactly the sort of testing one does at home.
Also biopsy is by its nature very site specific and not particularly accurate unless the site is representative of the body as a whole.
i'm sure the seven site skinfold is more accurate than the three?
But anyway, like above said make sure to have somebody with experience and also repeat 3 times or so to see how reliable the tester is.

Validity of Six Field and Laboratory Methods for Measurement of Body Composition in Boys
Lisa Parker, John J. Reilly, Christine Slater, Jonathan C.K. Wells and Yannis Pitsiladis
Objective: To determine the validity of the following six body composition methods against a reference method (three-component model): air displacement plethysmography (BODPOD); estimation from body density using BODPOD; skinfold thickness using the Slaughter equations; bioelectrical impedance, both leg-leg (TANITA) and hand–foot (Bodystat) approaches; and total body water.
Research Methods and Procedures: Forty-two healthy white 10- to 14-year-old boys (mean age, 12.9 plusminus 1.0 years) were enrolled in this study. Measures of body fat percentage and body fat mass derived from the three-component model were used as the reference method. Validity of all of the other methods was assessed by comparison against the reference by calculation of biases and limits of agreement.
Results: Mean body fatness measured using the reference method was 16.4 plusminus 11.6% and 8.7 plusminus 7.0 kg. Estimates of fatness from total body water had the narrowest limits of agreement relative to the reference (+0.9 plusminus 5.0% body fat; +0.5 plusminus 2.9 kg fat mass). For all other methods tested, we observed large biases and very wide limits of agreement.
Discussion: This study suggests that the validity of newer field and laboratory methods for estimation of body composition is poor in adolescent boys. For applications where high accuracy of estimation at the individual level is essential, only reference methods would be acceptable.
