Answer:
Gaining muscle weight & strength is possible without additional protein intake. Just look at the many vegan athletes! For muscle growth with moderate protein intake, I’d suggest you focus on the best sources of carbohydrate and fat at optimal ingestion times.
Right before your workouts, a simpler carbohydrate will fuel muscles readily so they can do the greater work required to stimulate muscle growth. Lower-fiber fruits (e.g. applesauce, grapes, melon) and starches (e.g. animal crackers, white bread, saltines, pretzels) are choices to consume in the hour preceding exercise and in the half-hour following exercise. For your regular meals, concentrate on higher-fiber complex carbohydrates like whole grains, potatoes and vegetables which break down slowly and provide sustained energy.
Consider incorporating medium chain triglycerides, known as MCTs. This type of fat is readily absorbed and metabolized so it may offer an alternative fuel source during longer workouts. Food sources include coconut, palm kernel oil, and dairy fat, particularly sheep and goat’s milk. As a supplement, a tablespoon of MCT oil contains 115 calories and 14 grams of fat, similar to cooking oils. Gut tolerance dictates that you should start with a teaspoon and increase dose slowly, reaching no more than 4 tablespoons daily. A modest 6-gram MCT dose in combination with other factors was used with success to treat muscle wasting in frail elderly*.

Consult with your medical care professional before using a dietary supplement or starting on an exercise program, especially if you have been diagnosed with a medical condition.
