My 17 year old son has been lifting weights, running and taking dietary supplements like protein powders and vitamins before and after his daily regime. I encourage him to eat nutritious foods as his primary nutritional source as opposed to the supplements. He doesn't understand that until those pesky testosterone hormones kick into action, he won't get his six -pack that he is killing for, even if he eats my veal parmiagiana!
His female counterparts in the high school cafeteria just don't eat....at all. They might sneak a piece of fruit and hide it under the table. But at all costs - NO ONE WILL SEE THEM EATING.
How have you dealt with teen eating peculiarities personally, or if you have credentials in this arena, we would surely appreciate your feedback.
