Protein Intake Calculator: limits and things worth knowing

• The official minimum (around 0.8 g per kg) prevents deficiency; it is not the amount associated with optimal muscle retention or growth. Research consistently supports 1.6-2.2 g per kg for people training.
• Older adults generally need more, not less, because of anabolic resistance — the same protein dose produces less muscle-protein synthesis with age.
• Distributing protein across three or four meals is more effective than concentrating it in one.
• High protein intake is not harmful to healthy kidneys, a claim that persists despite the evidence. Existing kidney disease is a genuine exception requiring medical guidance.
• General information only, not dietary or medical advice.

Is it private and secure?

Your privacy is built in. Protein Intake Calculator runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
