You probably don't know this, but I've been on a keto diet since 2011. The past 5+ years have been strict carnivore (no cheat days). So using fat as fuel has been my way of life. I don't need to read any more books or listen to podcasts - I get it. 😂 Preloading carbs has been an improvement pre-workout while cutting. I didn't feel the need for carbs when I was maintaining. It's different now and I'm listening to my body. I'm not telling others what they should do, so no need to take issue with my comment. I'm sharing my experience.
