Hi, I don’t really have any experience with intermittent fasting, and I’ve heard many differing opinions on the topic. However, I can speak a bit from my personal experience. When I was in college, I sometimes had 6 am cross-country practice, and I was never hungry that early.
However, I tried working out without eating beforehand a couple times and always felt like my performance suffered. I personally need at least a little bit of fuel to have a good workout in the morning, but I also know some people who prefer to just eat a big breakfast afterwards.
I think it really comes down to personal preference, but the most important thing is to make sure you are fueling well to stay healthy and strong. You can always experiment with a few different options, and see what makes you feel best.
A few of my go-to pre-workout foods in college were a piece of toast with peanut butter or a banana for something light. If I had a little more time, ~90 minutes before working out, I would have a bowl of oatmeal with peanut butter and fruit. If you’re doing cardio, carbohydrates will give you energy for your workout!
