Episode notes
BMR Misconceptions
- Greg Knuckles mentioned an example of people assuming their BMR is too low during aggressive calorie deficits.
- They base this on online calculators, but actual BMR can vary significantly.
BMR Equation Inaccuracy
- BMR prediction equations have large error margins, up to 300-400 calories.
- Most people assume these equations are accurate, but studies using Bland-Altman plots reveal significant discrepancies.
Sex and BMR
- Men generally have higher BMRs due to size and body composition differences, not inherent metabolic differences.
- When body composition is controlled for, BMR differences between sexes mostly disappear.
