I go to the gym early, 5am so I grab an iced coffee for a little caffeine jolt. By the time I get home at 6:30 I'm STARVING. I'll have something small like a 1/2 cup of ricotta or cottage cheese with cinnamon until it's a decent hour to have some real breakfast. Supposedly you aren't supposed to eat before cardio, it's better to do on an empty stomach but not sure what you can do if you don't go to the gym first thing in the morning.
