The deal is your body needs carbohydrates to ride at any type of intensity.
If your goal is to plod around as slowly as possible for random amounts of time, low carb/keto may suffice.
If your goal is to actually go out and push a little bit on the pedals, you need some carbohydrates. It's about as basic a nutrition/metabolism issue as there is, and yet threads like these still pop up because people buy into these ridiculous premises that are either completely fabricated or heavily misleading.
