I never eat anything before training. Literally any amount of food feels like it slows me down. I just take my morning supplements with a preworkout shake and get to it. I don’t think it’s great for everyone, most people I know prefer eating before training. In theory, it makes sense. No blood supply or energy going to breaking down food leaves more for the workout. Plus I think it has a favorable effect on neurotransmitters. More dopamine and norepinephrine versus serotonin with food. I’d say give it a go. If you don’t like it, try aminos, a protein shake, or small snack beforehand. You’ll just have to try it and see.
