I could've. I went through about a gallon of 2% or skim milk and a loaf of bread's worth of meat and cheese sandwiches each day, along with whatever was for dinner and a few snacks. I wasn't purposely doing GOMAD or anything, that's just what I normally ate.
I'm not entirely sure I've ever thanked my parents for feeding me during those years. I should do that, just to make sure.
Many if not most male teenagers should be able to do exactly that. Maybe the present generation is not active enough.
I know I wasn't a particularly athletic kid (80s and 90s), but I know I ate tons and tons and was always skinny. I was active, as was normal back then. When I started training (ok, exercising) and actually trying to gain muscular weight, I ate so much my parents complained and told me they'd be happy to be rid of me just for not buying my food anymore. I ate 2kg of meat per day, and this was far from all I ate.
Yes, you should. Good idea. Me too.
I can't speak for Santana's intent, but Dr. Kellogg's marketers did us a dis-service when they subverted the term "cereal" to mean processed breakfast product doused in milk for today's vernacular.
As for Sean Herbison's teenaged eating conquests, I wasn't quite as accomplished, but my mother appreciates that when I was craving extra calories as a teen, I'd just scrub off a potato, stab it with a fork a few times, and nuke it in the microwave. I wish I could hand that 90's kid a copy of SS and a squat wrack.
