CICO doesn't mean that every diet that works counts calories. It means that all diets require the calories you consume to be lower than the calories you burn. Including keto. Can some diets impact how many calories you burn? Sure. Not really to the extent that you need to worry about it, though. Can some diets be effective but unhealthy? Of course. You can follow CICO and lose weight by eating nothing but twinkies[1]. That doesn't mean it's healthy. At the end of the day, your lazy keto diet allowed you to consume fewer calories than you burned. You just didn't have to keep track.
