I Tested Apple Watch's Calorie Burn (vs Sports Lab) 

Shervin! Quality content as usual! I'm stalking the internet for the best deal on a does everything fitness watch. Training for a triathlon and want something to aid in run pacing, hr tracking, switching between sports easily. Looking for value but there's just so many frickin choices. Tell me what to get and why please! Money is not a big deal but I don't like wasting it on stuff I don't need either! I'm subbed ❤

If you did a test while walking that would have been awesome. Walking would give you a good baseline. You really can't mess up tracking walking.

Please also do it with samsung I want to which is better I have series 8 and my friend watch 4 classic which is better

hopefully this will inspire more videos like this!

On multiple times I’ve been looking for a video on a specific health topic and 5 out of 6 times Shervin did it!

I recommend watching "Quantified Scientist", he tests these regularly

@@Dev-Austin he doesn't test calorie tracker accuracy. I watch him too.

@neuroresilience true, I stand corrected.

So…. Wear all??

More wearables the better 😂

the comment I was looking for

This makes sense actually based off the error range of these devices. Additionally, it is probable that if you were to add up all of your workouts from the week and compare actual calories burned to device calories,any of these devices would be pretty close (except Apple Watch which seems to be heavily biased in one direction).

if you’re goal is to lose weight the priority is not to overestimate expenditure. So just take half the number it says you burned! Worst case scenario you get a slight bonus deficit which will help balance the innacurate calorie labels of products. You shouldn’t expect to burn a lot of calories in the gym anyways, calorie management is the main way you lose weight.

Thank you!! Means a ton

Same here. This Video is great for showing the accurarcy Problems of those watches but they are still Good for us in Terms of pointing in the Right Direction :)

Wow, congratulations on your transformation, I've had a similar transformation and I had lost about 40 pounds, the problem you'll face now is your body will try to get that weight back by making you binge eat, have a high protein diet so you don't feel much hungry and stay this weight until your bodyfat genetic setpoint lowers down to 150lbs

⁠​⁠​⁠​⁠@@Eatsuk33how long does it take until my bodyfat genetic setpoint to lower to the weight I want to maintain?

How so fast? so much?

​@@martinblazek1090 I don't really know, but I'll say a year or so after that you'll not crave so many calories

​@@Eatsuk33iv had this exact problem. I proper struggle with it.

Just trying to get better!

Glad it was helpful!

i'm honored, it's comments like yours that keep me going

yes! and height + weight

My pleasure!

This is an astute comment and quite frankly the biggest component to this whole topic that was woefully missing in the video. I’ve been religiously using an Apple Watch since it first came out which was right before graduate school for me and I’ve observed many different things with it and other watches. I’m an exercise physiologist and a dietitian so I have a deeper background with this topic than most and I’ve came to some determinations that this video did as well when discussing it with experts but he missed some things. The equations are either poor, don’t use weight, VO2 max, etc. so they’re not going to be calibrated to each person, that’s a HUGE flaw. Also, these watches sometimes use “active” calories or “total” calories like apple who tells you what the different totals are whereas some do this but give you the “active” calories only which makes it much lower than the total calories. There’s no such thing as “active” calories, that’s dumb and isn’t how things are done with exercise research. We just take some means of measure like oxygen intake/co2 output or heart rate and base our calculations off that and potentially your weight depending upon which variable we’re using. I use ACSM equations and others and just use the watch data to get a decent heart rate average for the duration of my workout and put it in cells of a spreadsheet and have a more accurate equation that uses my body weight, VO2, etc. to get much more precise measurements based upon MY BODY rather than whatever the watch is using to make its calculations. There’s error in all of this but my method uses my bodies variables at least to help better predict it though it’s never going to be as good as gas exchange measurements done in a lab as this video pointed out. Overall I think this video was great, but missed a few of those small things that some people don’t know about these different watches.

I had an experience with a treadmill run where my fitbit read my heartrate as 195-210 for over 15 minutes. I got a runner's high, so I pushed myself a bit, but I felt genuinely amazing after the workout. The heart rate reading and the experience just don't match up at all.

That's the plan!

@@ShervinShares And you are growing sooooo fast !!

Thank you!

Calorimeter vs Chick-Fil-A

That's not going to be useful information. Calorimeters account for all of the energy stored as heat in the food, but they don't account for the heat that gets wasted during the act of utilizing the food's energy, ie. the thermic effect of food. Food labels generally use food specific atwater factors that do account for an approximate estimate of the food's thermic effect, which means the calorie count on the food label should be lower than the calorimeter reading. And neither, by the way, account for the fact that the average human only absorbs about 80-90% (as low as 30% or as high as nearly 100%) of the calories they eat, the rest is wasted and excreted in the form of urine and feces--although there is no way to uniformly account for this as calorie absorption varies wildly from person to person based upon genetics (for example, I have celiac disease which causes fat malabsorption), lifestyle differences (incl. avg calorie consumption, physical activity, fluid intake), and the composition of your diet (principally fiber intake and degree of food processing)

i'm honored, thank you!

thank you!

You bet!

Exactly! Did the same and went -8kg in about 8 months, but with a couple diet breaks. Now I notice I've stagnated for the last 3-4 weeks so I will just bump the base calories down by 200 (I was on 1800) and that should theoretically start moving the needle again, slowly.

yup very fascinating!

that would be cool!

Thank you!!

Glad you like them!

he used total and I am not sure if it is good or not. Total should be used when you think about it but on the other hand this can be not that accurate because your resting calories are estimated only. So maybe showing active calories should be a way

thank you so much!

It looks like it’s total from this.

exactly. I am curious but I don't see any respond here

I wondered about this too. I only pay attention to my active calories burned and not total calories. Apple Watch will also tell you that for certain workout types, you're going to be estimated to burn calories at the same rate as a walk (which is what climbing workout says which is what I do), so it's fair to say that those type of workouts are totally just estimates. Would also have been interested to see less cardio comparison and a strength-focused workout.

Thank you! That means so much!

thanks!

probably not, the heavier the watch, less accurate will probably be, because of the movement and less stability in the arm and less contact with the skin

This!! /\

thank you!
