Diet to gain muscle/weight

I am trying to gain weight by gaining muscle. I have a pretty low body fat percentage, around 6%, is it healthy?
I have a weight-lifting routine and what i worrying is my diet.
Can you please suggest me a diet that is suitable for me? thanks.

You are still at the beginning of your puberty and will gain muscle as you get older. You are growing as you wrote so you are tall for your weight and appear thin. Your weight is normal for your age. Suggest you eat 3 meals a day, with snacks between meals, and try to eat a Heart Healthy diet which will give you the nutrients, vitamins and minerals your body needs, and help with possibly preventing future disease states. Heart Healthy diet which is a moderate fat diet and a moderate fat diet means = using polyunsaturated (omega 3, corn oil, nuts, etc) fats and monounsaturated (olive oil, canola oil, peanut oil, etc) fats, no saturated fats (high fat snack foods, butter, fat spreads) and no trans fats. Eat low fat meats (chicken, fish, loin of pork) or non-meat sources (soy products, nuts), low fat vegetarian combinations (rice & beans, pasta & beans, low fat cheese & pasta), low fat and substitute dairy products (1% milk, low fat/fat free yogurts, low fat soy milk/soy yogurt), use plant oils, non trans-fat margarines, and eat a lot of fruits and vegetables. Eat daily high fiber breads and cereals (oatmeal). That is great you are doing weight training. That will help you gain lean muscle mass which does weight more and bulk you up. You can also try yoga exercising which is strengthening your body gently from inside out. Suggest drinking either nutrient dense drinks (in addition to eating your meals) such as ensure or make your own milkshakes - soy yogurt, soy milk, and frozen fruit blended together; or milk, ice cream, and frozen fruit blended together for extra calories, protein and nutrients to help increase your weight. Thank you for your question.
