Hume Pod
The smart body composition scale, $229
The Hume Pod (Hume has also sold it as the Body Pod) is a body composition scale with a handle. You stand on four weight sensors and hold a hand grip with electrodes, so the 8-frequency bioelectrical impedance (BIA) signal runs through the arms as well as the legs. That is what makes segmental readings possible: separate figures for the right and left arm, the trunk and the right and left leg.
What each scan reports: weight (9 to 400 lb in 0.1 lb steps), BMI, body fat percentage, fat mass, muscle mass, skeletal muscle mass, visceral fat, total, intracellular and extracellular water, protein, bone mineral content, basal metabolic rate and heart rate during the scan, plus the segmental breakdown.
Hardware: 12.7 by 12.7 by 1.1 inches, a 2.8-inch display, Bluetooth, and a rechargeable lithium-ion battery that Hume states lasts up to a year per charge on average. Hume states up to 24 user profiles, each with its own Hume account. 1-year warranty from Hume Health.
How BIA readings behave: body composition figures from any BIA scale are estimates calculated from electrical impedance, height, age and sex. They shift with hydration, meals, exercise and time of day, so the useful number is the trend from scans taken under the same conditions, for example first thing in the morning before eating.
