Fasted training

Hi guys, what’s your personal experience on fasted training at high intensity! I’ve found for myself I perform better in the morning/lunchtime before having anything to eat! Did Mount Goode+2 this morning and had only a banana after the 2nd interval (18 minutes @threshold)! Previously when tried to eat 3 hours before the ride I feel sluggish and tired and hungry and can’t wait to get off the bike, sometimes I even fail to finish! I’d really appreciate any views on the above!!
Thank you!!
