That's a crazy diet.

Feeding a teenager going through a growth spurt a healthy diet is no joke, and even harder when they’re athletes. Anything that gets them to eat whole foods instead of junk food to fill that gap is far from crazy. Twelve eggs is on the order of 700-800 calories anyway, it would barely get a third of the way there.

Eggs are a cheap meaty protein. Meat is healthier, but more expensive. (Unfortunately, a side effect of that diet is--if sustained beyond growth spurts--it trashes your cardiovascular system.)

Worked great for me. I was on swim team and did weight lifting and got shredded.
