exercise is beyond important which my wife and I do in spades, but the crazy thing is what happens when you fix the diet at a foundational level. For example, my wife has MS and due to carnivore alone (lion diet specifically), she is off both anti-depressants and generic adderal (common for MS patients). That alone is worth whatever silly risks are associated with lack of vegetables (and having gone over a year on this, I'm not sure what those risks are)
