Frequently Asked Questions
What is a normal BMR?
Typical values are 1,200–1,600 kcal for women and 1,400–1,900 kcal for men, depending mainly on body size, age and muscle mass.
Can I raise my BMR?
Adding muscle mass and staying active nudge it up slightly. Crash dieting drops BMR temporarily, which is why very low calorie diets often stall.
