How accurate are those calorie burn estimates from my activity tracker?

I've been running for 5 years and recently started tracking my calories more closely, but I'm finding that the estimates from my activity tracker feel way off. For example, during a long run, it says I burn 800 calories, but I think it should be higher based on my heart rate and pace. Has anyone else noticed discrepancies with their devices? How do you adjust your tracking to compensate for this?

Lowkey, those calorie counters can be hilarious sometimes. i remember once it told me I burned 900 calories after an hour of light lifting. Bruh, I wish! I mean, lifting is great, but it ain't cardio, lol. I feel like they just inflate the numbers to get people hyped.

Activity trackers often struggle with accuracy, especially for calorie burn. Factors like your weight, metabolism, and even the way you run can significantly impact the numbers. I remember doing a 10-mile run, and my watch calculated around 800 calories, but based on my heart rate and exertion, I felt like it should've been more. After doing some research, I found that some trackers underestimate calories burned in higher intensity workouts. To balance this, I usually estimate my burns manually using formulas based on my weight and pace.

Facts, the numbers can be wild. Like, my tracker says I burn 500 calories lifting, but I'm just trying to vibe and maybe get 200. I just eat what feels good and don't sweat the discrepancies too much. At the end of the day, it's about how you feel and progress, right?

I totally get that! My tracker says I burn a lot too, but I've found I have to adjust based on my own observations. You can't always trust the numbers. Sometimes I look at how I feel after a run, and if I feel drained, I know I probably burned more than what the device says. Have you tried using a heart rate monitor alongside your tracker for a more accurate read?

I used to rely heavily on my fitness tracker for calorie estimates, but I've learned they can be pretty off. When I first started, it said I burned 600 calories during a moderate workout, but I felt like I was working way harder. Now, I combine my tracker with a manual log to adjust my intake based on actual effort levels and how I feel post-workout.

I recommend cross-referencing your tracker with something like Cronometer or MyFitnessPal. Both let you log activities and calories more accurately. Using different sources gives you a better picture. Also, don't forget to listen to your body. Sometimes, what you feel is more important than the numbers. If you're feeling strong, then keep pushing!
