Not sure if this thread goes here or not, but it directly links to Diet and Nutrition.

Does anyone have one of these scales that tell you your bf%? If so, are they accurate? How much do they cost? And are some better than others?

It is about $40 for a body composition test at my gym so I thought I might check out one of these scales so that I can keep track every week. Your help with this would be great.

No they aren't accurate. Drink a few glasses of water and watch your bf mysteriously change. Also, do a search.

Forget the scales. Waste of money. Get some cheap calipers.

It should change when you drink a glass of water. If it isn't fat, what is it? LBM. That is a sign that the scale works.

For accuracy the scales are not great, but for consistancy, they are fine. They are a means to track your progress and they do it quite well, actually.

No, its not a sign its working. When you drink water, you change how the electricity is conducted through your body, so you'll get wildly different numbers based upon how hydrated you are.

Also, my understanding is that with the scale BF% tests, the current goes through you legs, so it is also inaccurate based upon where you carry your weight.

I've heard your numbers will be thrown out of whack if the soles of your feet are wet. Dunno if it's true.

Wildly different readings?... Yet the second paragraph shows signs that you have never used one. Have you used one personally? What were these "wild" readings you speak of?

Yes, feet need to be dry.

yes, I've used one for wrestling certification before, and it was a terrible experience. I was supposed to wrestle 189, but for some reason I had registered at 9% bf when I was NO where near 9% (more like 18%), and I had to jump through all sorts of hoops to get another attempt at being certified. This was 5 years ago, but I doubt that the technology has changed much since then.

When it comes to electronics, 5 years is a lifetime.
