Frequently Asked Questions

Frequently Asked Questions

How much protein do I actually need?

For body composition goals, 0.7–1g per pound of bodyweight (1.5–2.2g per kg) is the evidence-based range. Higher protein is more important when cutting (preserves muscle) and less critical when bulking.

Are macros more important than calories?

Total calories determine weight change. Macros determine body composition — high protein preserves muscle during a cut. Both matter for optimal results.
