Interesting thoughts. Something that has been on my mind as well. I was initially a HF/LC "champion so to speak among my friends etc. I lost lots of weight, got my type 2 diabetes under control (my own doctor says reversed) and overall improved my life. But when it came to my workouts (krav maga) I always felt something was lacking. Through some more carful reading, glycogen hit me. What are some of these people doing for activity? If you do heavilly glycotic exercise (crossfit,martial arts, HEAVY lifting) while trying to low-carb, your gonna have a bad time.
For myself, I don't do keto as often (kinda happens by accident now) and eat way more starch (sweet potatoes, potatoes, plantains) and my actions @ krav have gotten much more explosive and quick. I have come to think that keto is just the gateway to retrain a broken metabolism,
then slowly re-introduce carbohydrate depending on activity.
Everyone just needs to experiment.
