Im 20 years old and as of tommorrow i decided to give up meat and dairy products, i already lift weights so im looking for a diet to keep me healthy and to maintain and build more muscle mass so what i came up with is this. (bear in mind i am gluten intolerant) Carb/protein sources - Brown rice,Lentils,split peas. Proteins/fats - Almonds,cashews. Orange vegetables - Sweet potato/pumpkin/carrots etc Fruits - Just about anything. Vegetables - Broccoli,cauliflower,Green peas,cabbage,brussel sprouts. I won't be eating soy ether or soy products like tofu etc. Any additions to the lists or advice is much appreciated, Cheers .
