Protein Intake Calculator – FAQs

How much protein do I need per day?

+

Active people generally do well on 1.6–2.2 grams of protein per kilogram of bodyweight per day. Those dieting to lose fat benefit from the higher end to preserve muscle.

Can I eat too much protein?

+

For healthy people, high-protein diets are safe. Intakes above roughly 2.2 g/kg offer little extra benefit for muscle but are not harmful, provided you stay hydrated.

Does protein timing matter?

+

Total daily protein matters most. Spreading it across 3–5 meals of 20–40 g each modestly improves muscle protein synthesis compared with one large serving.
