I did the same thing in my early 20's. Was hitting the gym very hard and hit Wendy's up on the way home every single goddamn day.You can get decently healthy food at fast food you just have to try a bit. And like you said sodium is generally the killer for most. I remember back when I was trying to gain muscle and didn't want to buy powder I'd just eat at Wendy's for lunch basically every day getting 2x Jr Bacon Cheeseburger w/o mayo + chili. I forget the actual protein off the top of my head but it was like 30g or something. The fat/calories were pretty in check the only killer was sodium. This was back when all this was on the dollar menu so I'd eat for 3 bucks.
Except... I was getting the triple cheeseburger, large fry, chicken strips, large soda and occasionally nuggets. Did I mention I was huge and diabetic by the end of that?
