Never heard of it.
I'd get the eyeroll if I even offered to take my wife to the movies. She hates going to the movie theater, which is fine by me.
Although my wife still gives me the gears for taking her to the "Lone Survivor"
I read that DeCaprio spent the night in a bison carcass and went on a raw meat diet while preparing for the role.
I've never bothered to look up his personal beliefs or practices, but actors at that level are frequently required to take drastic steps in order to get into character, be it getting incredibly jacked in a crazy short time, gain 60 pounds of fat in an incredibly short period of time, or chain smoke cigarettes which often includes practicing chain smoking during preparation. I haven't seen the movie yet, but if he is indeed a convincing character, I would not be one bit surprising that he took some drastic measures. Reportedly, the entire cast of the the movie The Grey actually ate wolf meat both in preparation and during filming.
Gaining/losing weight is one thing.
As an attorney, I have a real hard time believing the production company's lawyers would allow them to have requirements for the actors such as eating raw meat or sleeping in a buffalo carcass all night (presumably in the cold if the movie trailers are any indication) to get into character. It makes for a good story, but it is just not realistic in today's society. Can you imagine how much money that company would have to pay out if DiCaprio died because of hypothermia or because they made him eat raw meat? Nobody is going to take on that much liability for a movie that might flop at the box office and only net a few million in profit.
You are assuming that the production company forced him to do this

Leonardo DiCaprio has taken things to the next level for his role in The Revenant. To prepare, the actor not only camped out in the wilderness: he slept in an animal carcass, ate raw bison and went for regular swims in frozen rivers.
“I can name 30 or 40 sequences that were some of the most difficult things I’ve ever had to do,” he told Yahoo Movies. “Whether it’s going in and out of frozen rivers, or sleeping in animal carcasses, or what I ate on set. [I was] enduring freezing cold and possible hypothermia constantly.”
Check out the movie Man in the Wilderness with Richard Harris... This is basically a re-make, more or less...
