A body fat meter is a widely available tool used to measure the percentage of fat in the human body. Different meters use various methods to determine the body fat to weight ratio. They tend to under-read body fat percentage.
In contrast with clinical tools, one relatively inexpensive type of body fat meter uses the principle of bioelectrical impedance analysis (BIA) to determine an individual's body fat percentage. To achieve this, the meter passes a small, harmless, electric current through the body and measures the resistance, then uses information on the person's weight, height, age, and sex, to calculate an approximate value for the person's body fat percentage. The calculation measures the total volume of water in the body (lean tissue and muscle contain a higher percentage of water than fat), and estimates the percentage of fat based on this information. The result can fluctuate several percentage points depending on what one has eaten and how much water one has consumed prior to the analysis.

Famous quotes containing the words body, fat and/or meter:
“The whole body of what is now called moral or ethical truth existed in the golden age as abstract science. Or, if we prefer, we may say that the laws of Nature are the purest morality.”
—Henry David Thoreau (1817–1862)
“Holly Golightly: You know those days when you’ve got the mean reds?
Paul: The mean reds? You mean like the blues?
Holly Golightly: No, the blues are because you’re getting fat or maybe it’s been raining too long. You’re just sad, that’s all. The mean reds are horrible. Suddenly you’re afraid and you don’t know what you’re afraid of.”
—George Axelrod (b. 1922)
“His meter was bitter, and ironic and spectacular and inviting: so was life. There wasn’t much other life during those times than to what his pen paid the tribute of poetic tragic glamour and offered the reconciliation of the familiarities of tragedy.”
—Zelda Fitzgerald (1900–1948)
