Rather than an actor doing a take, this is a person on camera who is sitting there thinking about everything they are saying and how it is going to be interpreted. Women starve themselves on the show and before the show to get skinny. They aren’t going to wolf down a steak. The guy, likewise, isn’t going to eat a ton. They both probably eat after.
My wife has said before that she wouldn’t be able to eat on that show.
Not everyone can eat like Tom Cruise eats a rib in The Firm. Sorry, the gif wouldn’t link, but if you click here, you can see the joyous moment.
