Something they didn't mention, but is important, is consistency. For weight management, a scale doesn't need to be accurate, but it does need to be consistent. This is definitely also a factor in measuring calories. If the wearables are consistent in their readings, they still provide useful data.

Yes consistency is more important. You can have an accurate tool that cost a lot and is bulky but doesnt matter if you use it once in a while since theres so much variance between the measurement. If you have a lower accuracy measuremnt but more consistent that can collect a lot more data in time, you can at least improve on based on the trend.

YES. There's really no reason to wear a backpack worth of equipment going around if your goal is to track weight progression. Whether your goal is to gain muscle mass or lose weight, it's just not feasible to go for these equipment that provide max accuracy. The reason why smartwatches are so widely used despite its obvious inaccuracies is they are what they are, just a watch. Easy to wear and forget about. Gives you consistent estimates which you could then measure your weight daily and adjust your diet/exercise according to results. That's always going to be the best way to go, not wearing 20lbs of equipment lol. 😐

Well if I’m actually burning more calories than my watch is telling me, I’ll take that as a win because it’s way better than the vice-versa.

Mine's been telling over 3000/day almost everyday the last week or so. I'm feeling pretty special.

I tested Samsung Galaxy Watch 5 Pro and a Polar H10 on a treadmill. Same Time same Velocity. The data was almost identical. Only 5 kcal off by the Watch 5. Its incredible that a watch with only optical sensors is 99% accurate to a ECG Cheststrap.

doesn’t matter as long as you stay consistent with your goal, use whatever number as a baseline and adjust as needed. Eat more to gain weight eat less to lose weight. Of course its more complicated than that but in general thats how you do it

Excellent video, I didn't find anyone else who talked everything about this subject!

This is very interesting, as a person that works with these things for a job I know that they are not that accurate but at least for energy expenditure I think it is good to have some sort of bench mark and for it to be actually lower than what the real expenditure is (as measured in the lab) - this way if you are going off of that number to inform you how much you should be consuming you are still on the side of slight energy deficit, and yes that's for the freaks like me that actually track calories and macros.

Great study. What's the smartwatch used on that?

All right, very interesting. Wonderful presentation. Thank you.

Good running technique that does not harm the body. Nice to see. You get rid of less energy if you lift your legs more, but if you are looking to burn calories, the style is perfect.

my garmin keeps it good enough for me to have lost 60 pounds based on a daily caloric intake/defecit. i'm good. also, if your actual calorie burn from the leg device is higher than your watch, wouldn't that be counterproductive to weight loss? if you think you have less calories than you actually do, and your weight loss method is caloric, then you will intake less calories going by the watch right?

So, I'm a big guy, and I had the problem of all of the trackers over-estimated my TDEE because of assumptions they make about body composition. Someone who is 6'5" and 400 pounds can't just double the numbers for someone who is 5'9 and 200 pounds, because small errors in how they factor in body composition will be magnified when you just double everything. I didn't specifically try a garmin, though, just a samsung phone and a fitbit, and garmins look nicer (and should be for the price) - maybe they did their math better.

Too minimalistic, it needs more parts and robotic sidekick to shout out when you are running to calculate calories accurately.

What proof is there that his device is more accurate? This was just 3 sets of numbers from different devices, any of which could have been the closest to accurate.

I kind of assumed it wasn't based on the title. I just figured something's is better than nothing. A ball park estimate was better than a shot in the dark so to speak.

Reporting error rate for smart watches, when 1 smart watch brand was tested on 1 person is a bit of a stretch, especially considering each company uses a different combination of HR sensor and software...

These equipments are very convenient to use compared to just a watch on your wrist. What a time to be alive!

It really depends on how you use the data the watch spits out. I use mine to compare to other workouts I do during the week. Calorie count is just another metric.

I'm a scientist that studies thermodynamics of chemical reactions within the body. The most important factor is the delta energy value, meaning the change in energy values, rather than the absolute energy value. What this means is that measuring the change in your calories from one day to another could be a better use for the watches. Limitations: With that said, when you get more fit, your body will become more efficient with energy usage, so you'll actually use less calories, and this complicates the use of the delta value (after all, thermodynamics is for systems in equilibrium, not when they are non equilibrium). Conclusions: use it as a good reference and to motivate you to keep exercising, rather than quantify your body's energy usage.

Did that breath measurement mask restrict breathing compared to not wearing a mask? That might affect calorie burn.

I think it takes in to account your basal metabolic rate too

this video is quite dated, even at the time that it was produced. For example, the Fitbit will also use body composition in its calculation. Older versions of Fitbits struggled with calorie burn for exercises such as stair climbers and bicycles where your arms were relatively stationary. However, that has changed and they are far more accurate. That said, if you are looking for something to give you an accuracy down to the calorie, then that is simply absurd. I started tracking my daily calorie intake, usage, and weight for a 3 month period. Over that period I calculated an error of only 138 calories per day, (4%) and the majority of that is due to rounding up calorie intake.

My wife has a fitbit and I have a garmin. We train together, eat the same things and we're only a year apart in age. My garmin gives me way higher calories burned then her fitbit. We never take calories seriously because it's all in the math of the company's algorithms and they're idea of measurement. It is a good tool to keep motivated though.

Watches are only meant to be a guide to give you an average, which is clear to me because I’m a pretty thin guy and after a bike ride it says I only burn about 30 to 40 cal which is inaccurate, because I know with my body type I’m burning way more.

If your Apple Watch says you burned 300 calories the answer is Yes. If you believe the Apple Watch is underestimating the caloric burn the answer is still Yes. If you believe the Apple Watch is overestimating caloric burn......Yes.

My bixing sessions often say I've burned 900 to 1k calories. Be nice if that number was low.

i find it a little hard to belive that such light workouts of 5min lead to calorie expenditure in the hundreds. For example the stair climber one, it seemed like a fairly light exercise, and that amount of calories burnt meant that in an hour she would be burning something like 1600 kcal, wich is probably over her bmr. The fittrackers are unreliable(in my experience by considerable overestimation) but this sistem doesnt seem that accurate either.

Ok, but is anyone else glad that it underestimates? I've seen a couple other studies that all seem to align with the ideal that watches are more likely to underestimate than overestimate.

can we try with an apple watch instead

The research paper states: “The Smartwatch was an Apple watch series 1 (42 mm)” Also, the main problem was inaccurate and missing (!) heart rate data. I saw data of the Apple Watch Series 1 compared to the data of the Apple Watch Series 7. It has improved A LOT. The data of the series 1 was very spiky with a lot of gaps due to inaccurate IR sensor measurement when moving the wrist or holding things. This doesn’t happen anymore (or much less) on newer Apple Watches, but still on other smart watches. You can also use the ECG function of the watch for a much more accurate measurement. Btw, the researches were also using ECG. Apple now uses similar approaches to approximate body movement on newer watches. I guess this experiment is outdated (at least for newer Apple Watches).

From the running it is albe to use the measured metrics GSP, respiration, HR oscillation ect along with my bodyweight to much more accuratly mesure my V02 MAX. Once it has that information its much better at estimating calories from HR. Using gym equipement with power measments and thus accurate cal burn, my garmin is pretty close.

I’ve worn an Apple Watch since they first hit the market and haven’t lost a pound. In fact: during the pandemic I gained about 20 pounds like many other people. I was too lazy to hit the gym.

Did anybody actually believe that to be even close in terms of accuracy?

Well to be more precise you should wear a chest strap HRM as it is more accurate. This is a crucial piece in the algorithms used by smartwatch makers.

You can’t really compare this research tool to smart watches on the market. You are making a straw-man argument here. Engineers who made the smartwatches clearly knew that it won’t be as accurate. Maybe if the Stanford researcher made an actually “wearable” sensor that was more accurate than Apple Watch or Galaxy Watch this would have much more meaning.
