what kind of exercise? keto works fine both with endurance sports (running and biking) and strength training. Most people blame glycogen while it's usually an electrolyte problem. Keep your electrolytes in check and you will be able to do any kind of sport (as long as you're fat adapted, which can take a while).

Mostly cardio. Maybe I should be upping my sodium intake?

See Virta Health recommendations, they have a lot of information on electrolytes management on their website.
