My mother shopped at a small town grocery butcher store. She’d ask how much meat she’d need to feed X number of people. When I ended up dating his stock boy, he’d ask my mother if my boy friend was coming to diner and tell her she needed 2 lbs more if he was. Most of my life it’s been a running joke that teenage boys will eat one out of house and home. The regulations are shear insanity.
Guidelines that fit a 4 ft 8 in freshman girl are not going to work for a 6 ft senior football player. It’s plain common sense. The morons that came up with this should be out of jobs post haste.
It’s done to prepare them to have just enough food not to quite starve; but can still work as slaves. Cuba does this.
