Ok, lets try a different example:

John and Dave both eat the exact same 3 meals every day, for 30 days. When they both come home, they both do exactly the same workout. After the workout John has 50g of whey protein powder @ 110 calories, whilst Dave has 110 calories worth of coca cola (~290ml).

Now, given that protein helps muscle growth, and the more muscle you have, the more calories you burn, who loses the most fat after the 30 days?

You are mixing two variables here. If you get 100 calories from orange juice vs. coca-cola, then yes, they are the same. If both John and Dave are receiving enough protein prior to the coca cola/whey protein, then they will burn the same amount of calories as well.
