Calorie Requirements for Muscle Growth.

Calories for Muscle Gain.
Protein is important for building muscle. But you could eat 100% of your calories from protein, and you won't gain an ounce of muscle if your daily total calorie intake isn't greater than your daily calorie output.
To build muscle, you require a balanced diet that provides approximately 300-500 more calories than your maintenance calorie intake level. (You can determine the actual amount of extra calories you require to gain muscle without gaining fat by checking changes in your body composition measurements.) All the protein you require to build extra muscle will be contained in this amount of food, provided your diet is balanced properly.
A diet that provides 10%-15% of calories from protein ‘IS ALL THAT IS REQUIRED TO GROW MUSCLE’. Don't believe it? Consider this: Infancy is the time of a human's life when growth is the most rapid, and when protein needs are the highest. Yet, human breast milk contains only 10% protein by calories (versus about 30% for cow's milk).
This is more than adequate to meet the needs of a growing human infant who doubles its weight in 6 months and triples its weight in a year.
You aren't going to grow new lean tissue nearly as fast, (0.5-2.5 pounds a week) so forget about stuffing yourself with protein...just eat a balanced diet. Besides, when your protein intake is too high, you crowd out other calorie-dense foods from your diet that are needed to provide energy, and that spare protein for growth. Why do you think people lose weight on a high-protein diet?
Also, instead of eating more calories on rest days, you could just rest more than usual. That way, you'll create an energy balance surplus to grow muscle while sticking to your normal maintenance intake level. And, if you continue to stick to a maintenance intake level on workout days when your calorie expenditures are much higher, the energy balance deficit will begin to draw down your body fat levels.
Just remember: Exercising to build muscle without feeding yourself a proper amount of a balanced diet is like painting a picture with no paint on the brush. You're just going through the motions, and there's nothing left to show for your effort.
