im 24, 5'10 and weigh about 145 lbs. ive always been athletic, and always have lifted to keep tone. i am however, skinny, and i want to put on around 15-25 lbs of muscle mass. i have never really had a proper meal plan, and have always just eaten whatever i want. im looking to gain muscle (and the inevitable fat that will come along with it), and would like to get a healthy, effective plan....i know what is needed to achieve this, but i dont know what foods to get the proper calories and protein from. i would be supplementing with whey protein and would like a plan with this factored in. if anyone could give me a basic, healthy diet plan i would be very appreciated. thank you.
