If you've properly worked to failure the next day you should be sore. Your muscles are still repairing and adapting so it's still important to consume excess calories albeit with a focus on proteins that can be broken down into amino acids to repair and build new muscle fibers.
All of this is predicated by the intensity of your training. If you're doing something like training to failure then you can eat 18-24 calories per pound of body weight. It seems and feels unnatural at first but it works and eating a daily excess is mandatory for muscle mass and strength development.
