For everyone who dont know: You have to adjust for example your weight in the health app. Because the apple watch literally will need it to calculate the calories you burned correctly. So just adjust every week your weight in the app. (

the comment I was looking for

[@TheHeadincharge]

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).

[@KeCasgrimola]

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.

[@warpig6349]

I still rely on my Apple Watch, whether close to accurate or not I went from 230lbs in late February and to 148lbs now in September. I’ve been pretty happy with what my watch has been tracking so far

[@Eatsuk33]

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

[@sublimetulii23]

I lost 80 lbs in 8 months while wearing an Apple Watch Series 7 & learned quickly that the watch was inaccurate because I weighed myself in the morning & at night. I just now set my calorie goal to be 1,600 & know that I actually burn more like 1,200+ calories which is my true goal anyways. While I know it’s inaccurate, it still keeps me driven to reach that number, which has still made me healthier & more active & to be honest I’m completely ok with. Monitoring my sleep habits at least gives me some kinda data that I can go off of that I know when I had a good night’s sleep versus when I didn’t & has changed my sleeping habits to be better. I wish there were more accurate wearables, but for me it’s helped achieve my goals & live healthier so I can’t complain that much.

[@humanbeans7952]

Exactly. The point is not to get too caught up in the data, just using it to increase awareness of overall fitness

[@Pb44104]

I also did this 175lbs tracked all calories in and out, it’s off 20% or so for me. If my move goal is 800 and I do it everyday, even if I’m getting 500, I’m doing something everyday day when before I didn’t do shit. I think the key is that the exercise is not part of the diet, your deficit should be based on little to no exercise and exercise just speeds it up and is a fun healthy thing to do. You can lose massive amounts of weight with very little exercise, an exercise plan for weight loss is very hard, easier to just find ways to not eat than burn it off.

[@MarkJanner]

A professional told me don’t count the calories you work out losing just count the calories you consume and ignore what you lose if you want to lose weight and it worked I use my Fitness app to count calories lost 100 pounds less than a year. it worked the best advice I ever got.

[@notthatserious480]

I’m on a cut right now and I use a calories tracker app. But I always leave an extra 300 cals on the table after each week to account for caloric discrepancies in nutrition labels and calorie expenditure 👍

[@monkeymind7014]

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 :)

[@arbernuka3679]

300 for the whole week ? i Leave 100-200 every day for the same reason lol

[@griffduncan]

You can still use the watch as a consistent barometer. I.e., at the start of my diet I was eating 2300 calories + whatever apple gave me from my daily workouts. I kept monitoring my weight and found 1900 calories + whatever weight loss my watch gives me is the sweet spot. I’ve lost 13 lbs in 2 months doing that

[@Duci1989]

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.

[@mpayne199]

Are the Apple Watch calories you displayed the “Active Calories” from the workout or “Total Calories”?

[@EvGBeats]

It looks like it’s total from this.

[@kristof46]

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

[@kate-ne]

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.

[@shubham_srt]

just started watching this video, already want to comment thanks for this, it has been a question in my head too for a long time!

[@JayRock_2019]

I’ve usually always take my calories burned with a grain of salt, I just love tracking workouts in general to see trends in my activity and focus on areas I can improve. I love being able to see my paces on long runs, HR is definitely something I wish was more accurate though without having to buy a chest strap.

[@kylek29]

I've noticed the difference in calorie algorithms myself, each brand has its own set of values -- Fitbit tends to be on the "low side" (compared to other devices, not a lab) when estimating calories, and a lot of that seems to come from their look-up table where they use the exercise assigned (e.g. Ice Hockey has a different value than Power Walking) to adjust the rate of burn. Garmin skews higher and aligns with things like Wahoo and Polar. One thing I'm not positive about, but I suspect Fitbit's algorithm might be EXCESS calories you burned over basal metabolic rate, whereas some of the others appear to be cumulative. When you subtract your expected BMR from some of the higher ones, they tend to align with Fitbit. Best approach? Use this as a "relative" metric. If the watch says you burned +1000 calories above average, you were probably more active than usual .. or operating a jackhammer (tends to throw them off).

[@matthewmatzner4930]

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.

[@charleahar]

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.

[@wideopenmx850]

I noticed my garmin epix heart rate measurement would jump all over during workouts…probably due it moving around on my wrist too much or changes in angles doing push ups etc. I synced my Polar H10 chest strap to the watch and after doing that it was perfectly consistent throughout the whole workout. Having consistent heart rate data the whole workout is key for the watch to do it’s calculations correctly.

[@ShervinShares]

yes! and height + weight

[@KerryRasch]

I think people need to realize that you needed a whole lab and hundreds of thousands of dollars worth of equipment for your accurate results. The fact that a 49mm device that goes on your wrist is a couple hundred calories off is still an amazing feat of tech. Anyone who seriously thinks that an Apple Watch or a wearable is going to give you science lab results is out of their mind.

[@michaelcruz6454]

I’ll say this… when I was eating 2400 calories daily… my watch was saying I would burn about 23-2400 daily…. And my weight stayed stagnant … when I weighed 80 pounds more And was only eating 1500 calories and it would say I was burning 2500 calories , I lost weight… I wanna say from experience it’s accurate enough to see trends and make changes for weight loss

[@robinx8993]

hey, thanks for this video. can you see how accurate calorie counters are at restaurant? Like at Chick-Fil-A!!!!

[@ShervinShares]

Calorimeter vs Chick-Fil-A

[@jeremiahromagnoli7389]

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)

Shervin, just curious, is the reported Apple Watch calories the Active Calories or total calories? Apple Watch reports both when you select a workout type.

[@kristof46]

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

[@rikadreamer]

I want to thank you so much for this information. I was using my Apple Watch to figure out how much I burn versus how much I eat to lose weight. I was always frustrated on why I wasn't losing. The answer was that Apple gave me a higher calorie burn rate versus the actual amount. I know people say never eat back your calories... But I love food. So I learned it's best if I take off my watch and focus on calories in. You've got yourself a new subscriber!

[@KarstenSVideo]

The question is, which numbers got compared? There is a basic consumption that the body always has, even if you are not doing anything. Then there is the activity energy, which is additionally consumed during activity. With Apple, both values are added together for the period of activity. You can see this especially when you have spent different amounts of time on the identical activity. If the values from the other measurement system only show the activity energy in isolation, without including the basic consumption, the values cannot be compared as it was done in the video.

[@Sergygo]

How does this compare to a HRM chest strap? And how much more accurate are they?

[@Lizestechreviews]

Honestly, alls I need is a rough estimate. I don’t need it to be exact. It becomes a problem when you are eating a certain amount of calories BASED on that number. It becomes the differential between a calorie deficit, maintenance, or surplus. And at 100 calories in either direction, over time, you will either lose weight or gain weight if you eat based on the number on the watch.

Correction. Most people do NOT spend hours in the gym every week. MOST people do NOT go to a gym or even EXERCISE. I use watches to time my rest periods in between sweets while doing resistance training AND the duration of my cardio sessions. Regarding calories I only look at the trends as to whether or not I'm steadily increasing the number of calories burned.

[@jaredstrauss617]

On the cycling test did you have a power meter connected to the garmin?

[@willsgaming1481]

For the apple watch, I just multiply total calories burned by being active by 0.8 to get a rough estimate of how much i expended because I am trying to maingain. I don't want to gain a bunch of fat but im trying to avoid being in a calorie deficit at the same time, I know i cant exactly be at maintenece everyday but +50 or -50 calories over maintenece works as long as your consistant. If my apple watch says i burned 1000 move or active calories and its time for dinner, I just assume I burned 800 knowing it could have been as low as 700 or as high as 850 and to me it has helped me maingain and not gain any fat and add that ontop my bmr + thermic effect of food which ballpark but pretty accurate, if I did bmr + activity, I would lose weight because thermic effect of food isnt included in the bmr caculation.

What you didn’t take into account is that most of those watches have combined HR. The watch is off because the wrist mechanism isn’t touching the screen correctly. You should do the same test with a HR.

[@95mandem]

Great video but one big thing you missed. From my experience the Apple Watch calories and distance are useless on a treadmill but way more accurate when doing an outside run with gps as Apple Watch doesn’t know your speed or distance on a treadmill. It therefore cannot match your speed to a valley burn. I’m pretty sure the calorie burn it gives is based on your estimated speed. Also I have found that my Apple Watch closely follows (within 5%) the calories my gyms exercise bike displays. The bike is calculating based on pedal speed/ torque while Apple Watch only has HR info. Pretty impressive if you ask me.

This was a great video, I’ve always wondered just HOW accurate my phone/watch was and from what I’ve seen, it’s not very 🤣 the person who cracks how to get it very similar to the lab results will be a very rich person indeed!

"Take everything with a grain of salt... or pepper. I don't know whatever you like dude." This is peak humor. I got back into working out over the last few months and noticed that the Apple Watch always way over estimates my calories. I still enjoy seeing those high calorie burn numbers as more of a dopamine boost to keep working hard. I treat it more as gamifying my workout (what was my score) than actual scientific value. I don't use the calories burned to make any decisions on how I eat, I just eat 2,200 calories no matter if it's a workout or rest day. If you're starting, don't get hung up on the workout numbers just push yourself hard when you workout, eat mostly Whole Foods, and the results will come! Can't wait to see Shervin blow up!!

Keep working out!! And thank you 😂

[@ldproc0]

Outstanding information. Thank you.

[@ShervinShares]

You bet!

[@georgemichaelides4500]

with Cyling the equation is rather easy, if you have a power meter the calorie burn is almost a 1-1 ratio of Kj

[@MrDlinch]

Apple Watch report total calories burnt and active calories used - you need to pay attention only to active and it is usually twice less of total amount it calculates.

The good news is that most tracks are consistently inconsistent so pick one and measure that way. Just know, they’re all in accurate. However, you can use them to work harder. 🤷‍♂️🤙

Been watching the channel for a while and rewatching vids, you use the polar chest strap, id like to see you use the polar wearables
