Protien drinks were not designed to be meal replacements. If you were to substitute protien drinks for meals, you would starve to death. Once and a while you'd be OK to do so but on a regular basis, you might as well not be eating at all (well, that's overstated but you get my point).
A better choice for a 60 mile an hour meal is an actual MRP. Even these would barely qualify. They will go further than a regular protien drink as they do have some carbs and other goodies that will mimick an actual meal.
Use the protien shakes as they were meant. Post workout and to get your protien intake up. Use MRPs as they were meant to be used too.
Then you'll have few problems or worries.
Yeah, better choice would be the tuna. Real food over shakes ALWAYS!!!!
