This is the most worrying part by far. 6g is the recommended daily intake, 9g a day is considered far too much on a long-term basis. 39g? I wouldn't want to try it.

You'll fail at either choice, so for the sake of not putting all that **** in my body, I'd rather attempt the marathon.
I'm pretty sure the poundsaver cheeseburger is a double-cheeseburger. You might be best spending a few pence more for 26 regular cheeseburgers.
I think it's possible, and think you should try.

It might help a bit but probably more from the point of view of reducing the volume of food than for reducing the salt intake, the McDonald's buns will contain salt and probably a fair bit of it.
