Eh. If you're an American, maybe. They're a real outlier and it seems like bro science to me.

Canada recommends 0.8g/kg/day.

A diet put together by Lancet and friends comes out to 82g/10MG, which works out to 1.11 g/kg for an 80 kg man who eats 2600 kcal/day. So their recommendation is obviously below that, and therefore not 50% higher than 0.8g/kg/day.

The UK recommends about 55g/day for men and 45g/day for women, which is under 0.8 g/kg.

Australia recommends about 0.8 g/kg/day.

France recommends 0.83 g/kg/day (section 2.2.1)

Some of those guidelines are old (if that matters), but some of them aren't. The EAT-Lancet diet was designed quite recently.

Even if the American numbers are right, just swap the white bread for whole wheat bread and you'll hit the target. It remains dead easy to get adequate protein no matter what guidelines you use.
