Question for my strong friends: training fasted or not?

Context: had a long conversation with a friend who does CrossFit competitions. He says training fasted is terrible 🤣

I feel like it works great but I don’t want to discount his advice either. Maybe there’s a middle ground?

He says that I should take a banana, oats, protein and creatine right after training. I have creatine during training but I eat for the first time 6-7 hours after training.

(If you don’t train don’t answer please)
