Different genotypes have different levels of dependence on animal protien. They found specifically in India a pathway that made plant protiens better used. So what too much meat is varies by person. I think 1.5lbs of beef a day is probably more than enough for anyone. I did that for a year and my blood work was fantastic but it was definitely excessive to my needs.
I was rounding 1.36lbs (raw) of grassfed ground beef (85 / 15)mixed with diced hatch chilis and 2 mashed sweet potatoes. That was just lunch. I lost 30lbs that year, my tryglycerides recovered from my soylent months as well.
