And as Martin says, for better performance, you can stick your carbs postworkout where they do very little harm to fat loss. That can be a good strategy for keeping performance reasonable without sacrificing insulin sensitivity or the predisposition to fat burning that LC and IF give you, since the carbs are going to preferentially go to glycogen storage.
As for reduced performance, I like a fast and furious fat loss cycle accepting some reduced performance. That doesn't work so well if you have a lot to lose, however.
