Protein

The tables below are a guide to how much protein to eat each day.

It’s recommended that post-menopausal women eat 1-1.2 g/kg/day or 1.2-1.6 g/kg/day if they are trying to build muscle. The benefits level off after 1.6.

The calculation is slightly different for someone with a body mass index over 30 and is based on height and a correction factor so please make sure you use the correct table.
