Diet and fertility

Michol
I've read on Glow (and several other places) eating breakfast can increase fertility. I'm not really a breakfast person and when I eat the foods I like for breakfast (carbs-waffles muffins and so on) I get really tired and almost drowsy. 
Does this happen to anyone else? 
If so what do you eat for breakfast? 
(I'm not a fan of eggs & sausage). 
Thanks!
