Apple Watch resting calories

My Apple Watch is estimate for my resting calories or BMR is different each day. To my understanding, the BMR is supposed to be a constant number unless there are changes in your weight. They aren’t just slight changes either, I’m talking hundreds of calories of differences day to day. My active calories seem accurate enough

Apple Watch total calories difference Does anyone know why the total calories on certain days can differ from other days, even if the activities undertaken and the active calories burned are practically the same? It’s not even close, it’s grossly dissimilar. I obviously suspect the 14 Feb calculation is the accurate one, but it’s annoying there’s such a difference, unless of course there’s some metabolic reasoning to this - willing to hear any suggestions! Thanks.

My Apple Watch Does not estimate resting energy I have an apple watch series 7 with OS 10.3. I like being able to track my total calories (resting + active) however, every few days my watch does not estimate my resting energy during the night when it is charging. Normally, it estimates my resting energy when it is charging and when I am not wearing the watch. See images for examples of normal behavior and missing data. On both occasions, my watch was chaing during the night. Any ideas how to resolve this? tia [Re-Titled by Moderator]

Basal calories are those that your body burns during a day without any activity. Although the rate (kcal/day) may be constant (which depends on age, weight, sex, etc.) the total basal calories for each day will depend on the time you rest, sleep, and are active for that particular day.
