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. 😐

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.

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.

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).

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.

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.

Every product is a compromise. This leg sensor is utterly useless for commercial products because it can’t possibly be used for a mass market consumer device. 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.
