Can I be in if I don't actually weigh myself for a few weeks yet? Previous uneasy relationship with scales and numbers so would prefer to wait until my clothes feel reasonable before inflicting it on myself!
Re: body fat. This is pretty much totally lifted from my exercise physiology lecture notes (sorry Trevor) but explains it well I think! Have added little notes....
Methods of assessment:
-Densitometry
-Hydrostatic weighing (very accurate but not widely available...only specialised
university research centres etc)
-Skin-fold thickness technique (4 or 7 site most common)*. Accurate when done
by somebody experienced. Most accurate to get them to do the follow-up
measurements too....
-Waist to hip ratio
-Bioelectrical impedance (Measures amount of current flow through tissue. Fat- free tissue has greater conductivity = less impedance than fatty tissue)...but not
very accurate really. Used in those Tanita scales etc. Errors depending on
hydration status etc...and read somewhere that the scales tend to only measure
lower body fat-shudder.
-Other lab techniques - Radiography, CT, MRI, DEXA. DEXA is the technique
they use for bone scans. Apparently it's as accurate as the hydrostatic
weighing but don't think it's licensed for that indication so forget it!
