alt Hacker NewsWorth noting that like amino acids there are essential fatty acids as well, and most people have poor nutrition there... red meat isn't "only" saturated fat, but a fairly balanced fatty acid profile. You can have too much, but in moderate cuts it isn't too bad.
I usually suggest around 0.5g fat to 1g protein as a minimal, higher if keto/carnivore.
That's true, although fish has a better balance of essential fatty acids than red meat. Although, oddly enough, wagyu has a (much) better fatty acids profile than other types of beef, so you can justify the occasional wallet splurge on health grounds!
