To show how this can introduce huge error into pure calorie counting, I used my own data to calculate target calorie ranges using either a true low fat (30g fat per day) or ketogenic (70g carbohydrate per day) dietary pattern. (nourishbalancethrive.com)
Starting weight x 11 = Baseline calories Baseline calories + 400 = Caloric need Caloric need — 750 = Target calories Why didn't they just say subtract 350 from your baseline? (ellenratliffrd.com)
