A while ago my wife bought a Hume scale. You pull a handle with sensors up from the base, stand on the scale while holding the handle, and it gives health data far beyond what a simple weight scale does. That said, I’ve questioned the accuracy, and it definitely took some time to adjust, or should I say acclimate, to what it was reading about me.
The thing that really didn’t seem right at first was the heart rate, now with my Garmin watch to compare, I think it is about a heartbeat or two per minute above accurate, but that isn’t a drastic difference. The other thing I wasn’t sure about was body fat percentage, but I just did a scan at my gym that tends to be more accurate and it was pretty close there too.
One stat that all 3 sensors, the Hume, my watch, and this gym scale, all tell me seems to be accurate but the information is useless, and that’s BMI – Body Mass Index. The stats shared with me are 25.3, 26.0, and 25.2 BMI respectively and the Hume app says,
“25.3
High
A ratio of weight to height squared, widely used as a general health screening tool. It is generally regarded as an outdated measurement for health as it does not differentiate between muscle and fat. We have included it here for users which find it useful.
ⓘ Your rating is scored against medical and scientific benchmarks established for people your same age, sex at birth and height.”
And my watch bluntly says,
“Average BMI 26.0
Reducing your BMI to 21.9 can help lower your Fitness Age.
To help achieve this goal:
• Focus on both diet and exercise.
Cutting calories has been shown to be most effective for weight loss, but both regular exercise and calorie maintenance are important for keeping the weight off.”
However, further down in the description of BMI my watch also says,
“Keep in mind that BMI may not be a useful metric for everyone. Highly trained and muscular athletes, for example, may report high BMI numbers even though they are very fit.”
I don’t know if I’d call myself a ‘highly trained and muscular athlete’, but when my Hume app tells me that my body fat percentage is 14.8% and the fancy gym scale says it’s 14.6%, I’m definitely not cutting calories and trying to keep weight off… in fact I’m hoping to gain another 8-10 pounds this year.
All that said, I’ve learned that BMI is not a measure I plan on concerning myself with. And while it’s flattering to have such a low body fat percentage, I wouldn’t mind if that went up a bit while I focused on gaining more muscle. And so it’s good to have data to track but I’m not fixated on the numbers as much as the trends I’m seeing, as these numbers fluctuate.
I’ve learned that my diet does affect my weight and when I’m active I need to maintain my calories and especially my protein. I’ve learned that sleep affects my ‘health score’ and that sleep really is important for my strength, recovery, and overall health. And finally, as mentioned, trends matter more than concerning myself with daily numbers.
I’ve enjoyed tracking these and more data points on my Hume scale and Garmin watch, I do wish theses apps spoke to each other and shared data, but both put product loyalty (buy our watch AND our scale) over customer convenience. What I like is that I can see how my stats are trending, and while I do pay some attention to the numbers regularly, I’m not preoccupied or worried about them… which I think is healthy.
