Pay attention to what I said. You clearly didn't.
I said:
" Also, one slice of pizza is being compared to a big - mac - I don't think anyone considers one slice of pizza a meal. To get the same protein you would need about 2.5 slices of pizza, and then the2.5 slices of pizza has"
etc etc. I multiplied the pizza numbers by 2.5 to compare it to the big mac's equivalent amount, so that you are now comparing 2 entities with the same amount of protein.
So I never said that one slice of pizza has 625 calories, I compared like with like.
You DO realize you have to do that, right? To compare two things in this fashion you need to normalize something, and since the writer was talking about protein, I talked about protein.
In the same way, if you were comparing macaroni to as a main course to battered fish, you would not take the values for one individual piece of macaroni and compare it to a large piece of fish.
For main courses, we could compare things on a per calorie basis, per g of protein or any other basis, but you cant compare a slice of pizza to a big mac without altering the quantity.
