Mukwonago - By 7 a.m. Monday, senior Nick Blohm already had burned about 250 calories in the Mukwonago High School weight room.

He grabbed a bagel and a Gatorade afterward; if he eats before lifting, he gets sick.

That was followed by eight periods in the classroom, and then three hours of football practice. By the time he headed home, he had burned upward of 3,000 calories - his coach thinks the number is even higher.

But the calorie cap for his school lunch? 850 calories.

"A lot of us are starting to get hungry even before the practice begins," Blohm said. "Our metabolisms are all sped up."
