moniczkafromirl,
That is certainly not the experience we want you to have with your Apple Watch, and we will do everything we can to help you. Based on the information you provided in your follow-up post, we recommend the troubleshooting steps via the link below since your Apple Watch is not accurately tracking and calculating your calories.
Calibrating your Apple Watch for improved Workout and Activity accuracy - Apple Support
Please keep in mind that you can calibrate your Apple Watch to improve the accuracy of your distance, pace, and calorie measurements. Calibrating your watch can also help it learn your fitness level and stride, which improves accuracy when GPS is limited or unavailable.
With that being said, to perform the troubleshooting actions recommended by the article above, please read through and complete the steps in the section titled "Calibrate your Apple Watch."
We're recommending these steps because they directly address the issue you initially reached out to the community about, which is Apple Watch not accurately tracking and calculating your calories.
If the original problem persists after trying our suggested troubleshooting steps, provide us with specifics on what you see for more help, and we will continue from there.
Thanks for using the Apple Support Communities.
Cheers!
