Methodology & FAQ

What is the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is the energy spent at complete rest. TDEE (Total Daily Energy Expenditure) adds your movement and exercise to that baseline.
How accurate is the Mifflin-St Jeor formula?
It is currently considered the most accurate formula for estimating calorie needs in healthy adults, with a margin of error around 10%.
Should I adjust macros manually?
Our presets provide a balanced start. Bodybuilders often increase protein (40%+), while endurance athletes may skew higher towards carbs (50%+).
