Tracking heart rate for weight loss?

Hi,
I was considering buying the Fitbit Inspire tracker. Does tracking heart rate (on the Fitbit Inspire HR- more expensive) make any difference? Also I will want to start weightlifting so I’m wondering if it will track weights or just cardio? Any advice would help thanks
See photos for features of each watch (blue is added features on Inspire HR)

Tracking your heart rate might be useful for cardio, but is not necessary to lose weight and is not particularly useful for increased accuracy in calorie counting. I run, and I like data, so I have a Fitbit with HR tracking. I think it's great, so I'm not trying to discourage anyone from buying cool tech. I just want to be clear that it doesn't matter at all with regards to weight lifting, and only benefits the cardio junkie who enjoys graphs by providing that data. Even for folk with reasons to keep their heart rate in a given zone - this isn't a medical device, and you shouldn't trust your life to it. Added data is the only benefit.

Thanks a lot! So can I track calories burned by weightlifting if I buy the Fitbit Inspire?2 -
I have the inspire HR and I love it. I used to have the Flex 2 which I also loved. If you are looking for something to motivate you to move more the Flex 2 is budget friendly. But I’ll admit that I wish I bought the Inspire HR sooner. It has more data, and I like that. I wouldn’t say that it has anything specific that helps with weight loss more than any other device that motivates you to move more. But I am enjoying wearing a wristwatch again after depending on my phone for the time the past several years. I like the fitness data from the heart rate monitor and have seen improvements in my cardiovascular fitness score over the past few months. Both are waterproof and I wear them in the shower without issues. I also like the sleep data.1

No. No device will be accurate at tracking calories burned during weight lifting.

So... how can I track calories burned during/after weightlifting? For example if I want to lose weight/tone up and start weightlifting, how will I know I’m having calories out over in?1 -
You can track your heart rate with the Inspire HR. Tracking your heart rate is not the same thing as tracking your calories burned. The Inspire and the Inspire HR are two different devices. Of the two, only the Inspire HR will track heart rate. Both will give quite similar calorie tracking numbers, which will be determined primarily by the number of steps you take, and potentially by the intensity of the arm swing that accompanies that step (as measured by the internal accelerometer.)2

If your calories out is greater than your calories in you will lose weight.
The only tech you need to know if thats happening is a pair of scales.

Calories burned weight lifting are an estimate. You can do that without a device by entering “strength training” on myfitnesspall under cardio then enter the number of minutes.2

But if I do 30 minutes lifting 2lbs or 30 minutes lifting 20lbs, I will burn a different amount of calories?

So I will only know if I’ve lost weight in the long term? How will I know how many calories IN on one day after I’ve done weightlifting? What happens if I don’t know how much I’ve burnt exercising that I then overeat and gain weight0 -
My n=1 assessment is that from a data reliability standpoint using an observed TDEE approach is better than MFP's estimated NEAT + "measured" exercise approach. I've tried two different chest strap HR monitors and an Apple watch metrics and none have been as accurate as back-calculating overall TDEE using my daily weights and intakes.
Over the last 14 days I'm down 1.04 lbs by rolling 10-day average and my expected loss from this period based on my net calorie deficit over those days when compared to my observed TDEE was 1.117 lbs... a difference of 6.57%. I of course logged 100% of this time but was unable to weigh portions for 100% of entries due to a small fraction of meals prepared by others where portions were estimated.5 -

Here is an article that explains very well the difficulties of calculating weight lifting calories. https://www.sparkpeople.com/blog/blog.asp?post=you_asked_how_many_calories_does_strength_training_burn
Logging your food accurately using a food scale and correct entries from the database balanced against what your bathroom scale says over a period of several weeks will show whether you are in an energy balance, or at surplus, or in a deficit. Choose an appropriate rate of loss and activity level when setting up your account, for best results.3 -
@steveko89 I think I agree that the TDEE method is probably preferable to people who primarily do strength training exercises. I don't know if there is greater accuracy in that approach for those who prefer easily estimated cardio exercises, such as running - especially if one considers a long run once weekly of 10 miles or so, which is likely to burn upwards of 1000 calories. For runs under an hour, TDEE might be workable.0

In my experience it takes a little trial and error to work out where your maintenance calorie limit lays, but once youve worked that out you know that to be under that you lose weight, and over that you gain.
Keep track of your food and activity as well as you can (again, my experience, doesnt need to be to the nth degree) and you will learn where these lines are drawn.
Weight loss is a long game. It can fluctuate daily, down to simple things like bowel movements or water retention, so I personally never saw any benefit to worrying about losing weight per 24 hours.
I set up the app to lose 2lbs a week. If I lost 2lbs that week I was on track. If I lost less I needed to tighten up how I was recording my food. If I lost more I saw it as a win.
I also looked at that weight loss as an average. I found some weeks very little movement, then the next week a big drop. So if it was 8lbs over the month then all good. be that 2lb, 2lb, 2lb, 2lb or 1lb, 1lb, 1lb, 5lb.
Its a tortoise and hare thing, remember the tortoise.
Incidentally, I dont believe weight lifting burns a particularly high number of calories. It works absolute wonders for your body composition, and is great while losing weight to maintain muscle mass and lose more fat*, but as a weight loss tool itself there are better exercises (for burning calories).
*Purely hypothetical numbers, I dont have the actual stats to hand. If you lose weight with no weightlifting the weight loss will be (for arguments sake) 50% muscle and 50% fat. Weightlifting stimulates muscle growth/retention, and so losing weight while lifting will skew that balance more to 40% muscle and 60% fat.2 -

I get what you're saying and I can't disagree there are some limitations to the methodology but if one's exercise and activity is fairly similar week-to-week having one day where there's a higher expenditure than others isn't particularly statistically significant in terms of changing the average, maybe 100-200 calories which could easily be compensated for by some iterative observations. I'd also consider it an anomaly for someone's weekly routine to be centered around a single 1000 calorie expenditure.1 -

Instead of logging cals burned from strength training, I changed my activitly level from sedentary to light active and that gives me 150 or so extra cals /day which would cover cals from lifting and recovery from lifting. If after 4-6 weeks the results are different than expected, adjust cals up or down accordingly6 -

Yes, but not much more, as lifting doesn't burn a lot of cals anyway7 -

After 4-6 weeks, did you lose as much, more, or less weight than expected.4 -

Sure but you can do it with dice too.
How much accuracy does the Fitbit promise, what's the maximum error? What are you getting for your $$$?1 -
I personally think that the NEAT calculation that MFP uses way over estimates my calories burned. I prefer to use the output from my FB Ionic, I personally feel as though it is a more accurate estimate. Please note that for both I used the word "estimate". Neither is going to be perfect, but it can certainly be a good guideline.
Overall, I like using a FB with a HR monitor because I am a numbers geek and like to track EVERYTHING! The more data that I collect, the more accurate I'm able to measure various things.5
