If there’s a dataset available for daily weight and caloric intake, could TDEE be calculated using some simple math?
Potentially something like a regression for calories vs weight delta, with the intercept of zero being TDEE?
Yep. There are sample spreadsheets linked here: https://www.reddit.com/r/Fitness/comments/4mhvpn/adaptive_tdee_tracking_spreadsheet_v3_rescue/
