Frequently Asked Questions
What macro split is best?
A balanced 30/40/30 works for most people. Higher protein suits muscle building. Higher carbs suit endurance athletes.

Yes. The calculator works best when protein%, carb%, and fat% total 100%.
Should I count macros or just calories?
Calories determine weight change. Macros determine how you feel, perform, and recover.
