Questions

Three things people ask about these numbers.

How accurate is this?
Mifflin-St Jeor lands within roughly ten percent for most adults. It is a starting point, not a measurement.
Why is protein capped?
Past roughly 0.85g per pound of body weight there is little added benefit, and the calories are more useful elsewhere.
Do I hit these exactly?
No. Hit protein most days, stay in a reasonable calorie range, and let the weekly average tell you whether to adjust.
