I got a three point skinfold test done at a local gym and also used a bioimpedance device several times and took a rounded average. Both readings around 14%.
Bioimpedance devices are incredibly inaccurate.
The validity of how accurate the three point skinfold test is dependent on how good the technician is.
The majority of those who administer skinfold test don't know what they are doing.
A good technician will use a tape measure and pen when performing the skinfold test. The tape measure is used to find the precise site to calibrate.
The tester will measure at least twice to find the right spot. They then will mark the stop with the pen and use the skinfold caliepers.
If your technician followed this protocol and was experienced, you may well be 14%.
If your technician did NOT follow that protocol, they did NOT know what they are doing.
IF you are 14% body fat at 165 lbs, that means your Lean Body Mass is 141.9 (165 X 14% = 23.1 lb of fat. 165 - 23.1 = 141.9 lb of Lean Mass).
To get down to 10% body fat, you'll need to lose 7.3 lbs of fat. (141.9 lb Lean Body Mass divided by 90% = 157.33 lb body weight. 90% would mean you'd be 10% body fat).
The problem is that you rarely lose ONLY body fat when you lose weight. From what I've seen, if you do a good job, your weight loss will more than likely be 80% body fat and 20% muscle.
That means that your probably going to have to lower you body weight to 155 lbs.
With that said, what is the reason for wanting to drop down to 10% body fat?
