Re: What can I do? Son and Dad diet?
Your intentions are good, but if you mostly survive on cereal, you might become anemic. It sounds like you need more different types of food. Your family won't be able to call you anemic if you start eating nutritious food with iron in it.
You could try telling your dad that food with lower GI (slowly released energy) keeps you going for longer. Junk food and caffeine gives you quickly absorbed energy but the "crash" is worse because it burns off quicker. Junk food also doesn't have as many vitamins, minerals, and good quality protein.
