Belly fat, my friend, is a testosterone buster. And it's secretly turning you into a chick. Excess body fat makes a man look more curvaceous than cut and, if he's really unlucky, gives him a lovely pair of man-breasts to admire in the mirror. But that's not all.
Divide ground chuck into 4 patties, using your thumb to create a small well in the center of each patty. Liberally season the patties on both sides with kosher salt and fresh cracked pepper. Lightly butter the cut side of each bun, and add to the grill for 60 â 90 seconds, or until just toasted and browned. Add hamburger patties over direct heat and grill covered for 3 minutes on each side for medium rare plus. Remove from grill (or top with cheese to melt) and rest 3 â 4 minutes before serving.
1 Arrange the tomatoes and lettuce leaves on an attractive serving platter.  5. When ready to cook, brush and oil the grill grate. Place the burgers on the hot grate, onion side down. Grill the burgers until cooked to taste, 3 to 4 minutes per side for medium-rare. To test for doneness, insert an instant-read meat thermometer through the side of a burger into the center. The internal temperature should be about 145Â°F for medium-rare or, if using commercial ground beef, cook it to at least medium, 160Â°F.
