I’ve always wondered this exact same thing..
If you’re consuming sugars during a workout then you’re not exactly training fasted... And seems like you love spending time in the gym, I understand age might have to do with the higher volume and avoiding injury etc but I can do an arm workout that will have my arms feeling like noodles in 15 minutes... I would train fasted as well and will continue to do so once I’m able to train 100% again, but I also believe that whole “catabolism” thing is absolutely over pushed and over stated.. It’s horse shit.. The body isn’t going from states of catabolism to anabolism every other hour throughout the day depending what you’re doing, ESPECIALLY if you’re on AAS or TRT, that’s a 100% fact, that takes malnutrition, exhaustion/stress and TIME to happen.. If anything you’re targeting fat easier/faster when you train fasted... I know the whole “everyone is different” crew is going to attack me on this but doing Intermittent Fasting and training DC Style fasted gave me amazing results and I was my leanest at the weight I was at, and gained tons of strength... No catabolism issues with me, oh and I didn’t eat right after training, sometimes I’d eat 6-8 hours later...
