As it happens there’s an XKCD about it.
Larger animals are more energy efficient, and require fewer calories per pound than smaller ones do.

It depends on its age, activity level and metabolism. A warm-ish blooded active predator is gonna need way more than 1 human a week. It’ll be wandering its large territory looking for meals, not charging after candy bars.
A large adult is also likely too slow to catch a running human; one quick turn, inconvenient obstruction (huge tree, boulder, invincible hut) could result in a leg-breaking accident that the T-Rex would know better than to bother with. A young or adolescent animal would be way more dangerous though.
