"Meat toxicity"? That's a new one on me. I'm unaware of any problems with consuming large amounts of meat; provided, of course, that's it's good meat.
CW (conventional wisdom) warns off of meat because meat has fat, and CW holds that fat is bad. I don't find fat to be bad -- in fact, it's my main source of energy. Therefore I see no problem with eating as much meat as I like.
One problem that can arise from a diet of exclusively lean meat is "rabbit starvation". It's uncommon, but can occur (particularly in times of environmental stress) if there's not enough fat in the diet. Since you're eating vegetables and fruit, this will not be an issue for you; you're getting carbohydrates which are providing your calories.
For a sense of scale, I had half a pound of beef brisket at lunch yesterday, two-thirds of a pound of ground beef at dinner, and a handful of jerky during the day (somewhere around 500g). For a while recently, my partner was eating approximately 300g of dietary protein each day, almost exclusively from meat -- and that was part of the (medically-directed) process to heal fatty liver disease.
