But, I wasn't sure how it measures my body fat%.
Here's what I found...
"A small and completely harmless electrical current is passed through your body. The electrical current passes more quickly through fat free tissue like muscle than it does through fat or bone tissue. So...
The amount of resistance to the electrical current relates to how much fat-free mass a person has and their body density. Here's the first challenge...
Like all body fat tests, body fat scales don't actually measure your body fat percentage. They determine your body density. The examiner (or the scales) then uses a formula to calculate body fat percentage based on body density. Here's the key...
These formulas just predict your body fat. Unfortunately there is no one formula that accurately predicts body fat for the whole population. Differences in age, gender, ethnicity, body size, and fitness level all have a significant affect on the results.
Most scales can account for some of the basic differences such as age and gender, but take the actual body fat percentage they give you with a pinch of salt. What does this all mean for you?
Well, whether body fat scales measure your "true" body fat percentage or not doesn't matter! As long as they can accurately monitor changes in your body composition over time, that's all you need.
Your body position, the amount of water in your body, your food intake, skin temperature and recent physical activity can all adversely affect the results of body fat scales. So...
To achieve accurate, consistent results, you must standardise the way you perform each test. That simply means making each test with your scales as similar as possible. "
Ok.... but still I want to know if my fat is under OK zone.
By the way, I should disclose my fat % here... it is 29% >_<
Most of the tables I could find on-line say I am very close to the borderline between "Average" & "Fat"!!
29% sounds a lot especially when I compare it with my boyfriend's... 8.8%!!!
My goal is reducing it to 25%. Good luck to myself...
You're making me feel guilty for eating unhealthy stuff. By all means we don't eat much fast-food/junk food, but we do eat lots of chocolates, homemade cakes and meat etc kyaaaaa.... And I don't want to even think of how much fat I've harboured over the years. So out of shape for years already and worse now after baby T____T
