How can I intake more protein and more calories without eating a huge amount of food throughout the day, all day long? It's almost impossible for me to get in 3 meals a day, and small snacking all day isn't possible either. So what are some ways I can get in extra protein without heavy shakes/smoothies? Or some meals/snacks that have a lot of protein and/or calories in them, but aren't a huge amount of food (if that makes sense)! Thanks for the help in advance!
