Facepalm

A 200Lb adult needs a minimum of 140g of protein daily to remain healthy.

The standard recommendation is about 0.8g per kilogram of body weight. So 200 lbs is 91 kg, which corresponds with 73g.

There's some more recent advocacy for more protein, especially for active or older people, but that's talking about more than just the minimum requirements to be healthy, and more towards optimizing for performance.
