How your protein target is calculated

Your target is your body weight in kilograms multiplied by a grams-per-kilogram range. The range depends on your goal and how hard you train: a person who exercises lightly needs less than someone lifting five days a week, and people cutting fat need more to protect muscle.

The result is a range, not a single number. Anywhere inside it is a sound target, so pick the end that fits your appetite and budget. Protein supplies 4 calories per gram, which the calculator uses to show how much of your daily energy it covers.

Tips to reach your target

Plan snacksYogurt, eggs, tofu or a shake close the gap on busy days.

Frequently asked questions

How much protein do I need per day?
Most adults need at least 0.8 g per kg of body weight to avoid deficiency. Active people, people losing fat and people building muscle often do better at 1.2–2.2 g per kg.
Is too much protein harmful?
For healthy people, intakes up to about 2.2 g per kg are generally considered safe. People with kidney disease should follow their doctor’s advice.
Should I use body weight or lean mass?
Body weight is simpler and is what this calculator uses. If you carry a lot of body fat, a target based on lean mass avoids overshooting, so check your lean mass with the Lean Mass Calculator.
How should I spread protein through the day?
Spreading it over 3–5 meals of roughly 20–40 g each works well for muscle repair, but reaching your daily total matters most.
Do I need protein powder?
No. Whole foods can cover your target. Powder is just a convenient way to fill a gap.
