Not at the rate that we consume it. But having beef, chicken and pork once per week? Definitely something that is healthier for our bodies, the planet and the livelihoods of these animals.

I reakon this is the way to go. Some meat, better quality, better lives for the livestock. A steak once a week sounds ok to me.

Post physique.

More seriously, though, a steak once per week as your only meat isn't sufficient protein. Unless you want to faff about with vegetable combining.

Definitely? The reality is that there is no high-quality research which establishes the healthiest weekly frequency of meat consumption. We can't say whether it's 0, 1, or some higher number. The studies so far have generally been too short, relied on subject reported data (i.e. junk), used proxy metrics only loosely correlated with overall health, had small effect sizes, and failed to control for confounding variables (i.e. healthy subject effect).

Let's have some humility in this area. There is very little in human nutrition that we know for sure.
