Diners, Drive-Ins, and Dives, Food Network, Monday, 10 p.m.

The unhealthiest show on television is living up to its reputation this week, when expert over-the-shoulder commentator Guy Fieri comes to Boston Burger Company in Davis Square in Somerville. The centerpiece of the segment will be the Mac Attack, a half-pound Angus burger topped with creamy homemade mac n' cheese and bacon. It's admirable that Boston Burger Company tries to hit all three major food groups in one dish: Beef fat, cheese fat, and pork fat. Guy Fieri, as well as Adam Richman from Man vs. Food, either has some superhuman gene in his blood cells that destroys all his incoming cholesterol, or he's going to have a heart attack very soon.
