Protein Target: Your protein target is the grams of protein to eat daily to build or preserve muscle. Clinarix sets it at 1.6–2.2 g per kg of bodyweight — higher in a calorie deficit (to protect muscle) and slightly lower in a surplus. A 78 kg adult typically needs ~155 g of protein per day.

ƒProtein target (g/day) = bodyweight kg × factor · factor = 2.2 (cut) · 2.0 (maintain) · 1.9 (bulk)

How the Protein Target works

How is the protein target set?

We multiply your bodyweight by an evidence-based factor: 2.2 g/kg when cutting (muscle is most at risk in a deficit), 2.0 g/kg at maintenance, and 1.9 g/kg in a surplus where total calories already support growth.
